97 f250 4.6l engine pegs the temp gauge after start-up. the oil pressure light comes on then after a few miles down the road anti-freeze blows out the pressure cap (15LB) then the temp goes down ,the oil light goes off and everything is normal. no its not the thermostat, i changed that and it still does it. whats up with that?
View 14 RepliesI just bought a 97 f-150 from my dad, there are some electrical issue's but the main one seems to be battery drain.
I have noticed with the truck off key in my pocket, the a/c doors keep trying to move and the a/c head has power to it.
I know the engine has been replaced, with about 20k on it.
The temp gauge pegs w/o getting hot, and it even turned over once while we were getting in the truck. Again key in pocket.
When I purchased my truck 1999 F350 about 5 years ago, I was told it was on its third transmission since the awesome 7.3 diesel engine has 200,000 miles on it. At first I noticed that going up a hill with the truck empty would cause the tranny temp gauge to climb to 250 degrees F. Nowadays when I tow my boat or carry my camper, the temp gauge pegs over 250 and the overdrive light flashes steadily when I do any hill climbs. I have had the fluid flushed several times, and I have a large fan powered oil cooler too. I also recently noticed that the tranny heated up when the truck is just idling in place.
I just got back from burning man and during the 800 mile round trip the overdrive light started flashing at least 6 times and the temp gauge read over 210 the whole time, with it pegging over 250 during hill climbs. No fluid boiled out but I am very concerned that damage is being done.
Is it possible there is a clog in a line somehwere restricting the flow of oil? Or should I replace the tranny?
Just about every trip i take my temp gauge pegs and dinger goes off and check gauges lights up in the message center. It eventually will go back to normal or if i shut key off and restart truck it goes to normal. im guessing it is the temperature sensor for the gauge but not sure?? If it is, where is the gauge sensor located?
View 14 RepliesProblem: The exterior temp. gauge is blank.
It used to fade in and out and I discovered if I pushed the button that switches from degrees F. to degrees C. it wold come on for a bit, but no more. It's just blank.
I think I've seen a thread on here about similar issues but I was unable to find it. I'm also not sure how to take the overhead console off yet. The console consists of ext. temp gauge, sun glasses compartment, and compartment for a garage door opener.
Some truck specs:
Year: 2001
Model: F150 Super-crew
Motor: 4.6L
Mileage: 250,000
Color: Silver
Original motor, second transmission.
I have a 2002 supercrew 5.4 triton. My coolant temp gauge is acting up. When it starts up its obviously in the cold range but when the truck begins to get up to temp, the gauge only goes up 1/4 full. What it can be?
View 4 RepliesMy '97 F250 5.4L is pumping coolant on to the top of the motor which is burning off causing it to smoke like it's overheated but the temp gauge is operating in normal range. I'm losing coolant but can't see where. It's not going to the ground. It just pools up on the top of the motor. I've already replaced the water pump in the last 2 weeks because of the same issue. It stopped for a few days but now it's back again. Bad water pump from O'Reily's or is there some other issue here? I've checked while the motor's running and can't see where the coolant is coming from and there's no coolant coming out of the bleed hole in the top of the new water pump. I need this truck up and running.

Salvage Flood Title, looks like engine been replaced. (Not so proud of him).
Anyway, vehicle seems to run and drive fine, however, failed emissions test.
P0125 Code pops up, Temp Gauge is not working, pegs all the way hot after truck is running, changed out Both ECT's in front of engine, one is right beside the other, I guess one goes to PCM and other to Gauge.
Now Gauge is reading all the way cold, let run for over 30 minutes and still shows nothing on Gauge...
I am looking at a 1997 F150 with a 5.4 in it, guy who owns it says if you drive it down the street the temp gauge climbs and then the truck goes into limp mode but if you check the engine temp under hood it is nowhere near overheating. Where I should start to look for a problem here? If this is too complicated I will pass on the truck, its not worth it to me to get this truck if it is going to be a nightmare. I have a 2000 with a 4.6 that runs great so this would just be a spare for me, but would like to have it because its in such nice shape.
View 1 Replies1998 f150 4.6 4x4 auto 180k .... Runs 100% other than a strange and inconsistent overheating issue.
On cold startup truck will warm up. Then the temp gauge drops to practically 0. After 15-20 seconds gauge shoots up to max and then falls back to normal after 15-20 seconds. Then it'll go back to driving normally. At some point it pukes.
I own a 1997 ford f150 V6 engine and I have problems with the electrics. I turn the key on and the engine starts up runs great but I then look at the gauges and not one moves at all the. No fuel when i have just filled up,no tep,no oil,no battery all read nil. I went a drive and the speedo reads 0 it does not move but the truck drives great. Could it be a fuse, does a fuse control the gauges, which one it could be. I have lifted the hood and under the hood on the drivers side there is a box with small and larger fuses.There is one that is very small and the colour is white that's blown. Would you no what that fuse is for.
View 1 RepliesWas driving my truck I have a 97 f150 4x4 4.6L, btw. The heater started blowing cold air and I looked at the temp gauge but it was showing lower than it normally does and then, after a couple of miles or so I looked at the temp gauge again. By this time I was in my driveway. And it was overheating it might have been that way before I looked at the temp gauge again. But any way I opened the hood didn't see any leaks, all my hoses were hot except the top heater hose. Also checked the oil it was full and coolant was too, what this could be? Sounds like a t-stat to me? But could be worse. Also forgot to mention that the oil had no signs of water in there nor the expansion tank cap !
View 3 RepliesWe have a 2002 F-150 4.6L 4x4. The engine went bad and we bought a new engine (remanned ATK). Had this engine installed and a year later it was bad and was determined it was a manufacturer defect so they sent a replacement engine under warranty.
We had this new engine installed. The mechanic fired it up and it backfired through the intake. They claim that the compression is good, the fuel pressure is good, and the timing is correct. Can they check these things when the truck is not running? The mechanic is completely frustrated with the situation...
Everything I read leads to a timing issue but they say they checked it so before I go in there screaming I want to make sure it couldn't possibly be anything else...
I have a 98 F150 Supercab 4x4 with 4.6 and an auto trans. I have 107,000 miles on the truck. Recently developed a engine "tick". Upon start up the "tick" is very noticeable. Seems to go away after its been driven a few miles and everything comes up to operating temp. I have checked the exhaust manifolds, all studs and nuts are still there. There are no noticeable holes that I could feel in the manifolds. Read some other posts here that have the "tick under load". Mine goes away once everything warms up. What to look at or for?
View 8 Replies2003 F150 5.4L Tow Package 140k miles... Had coils, all plugs/wires replaced two years ago due to vibe climbing hills. Now at startup in the morning for a minute or two during idle, the engine vibrates severely then subsides and runs fine rest of day. Doesn't do this every morning. Truck lives in FL. The issue is either temperature related or moisture related. Ford service has the truck presently and attempting to diagnose from an overnight stay. They already 'fixed' the problem last week by replacing #1 plug/wire and resetting the power control module (pcm) but two days later the problem came back. Tech said today that the plugs currently installed are Bosch (any issue with these plugs?)

I've got a 2003 f150 with the 5.4 and 128,000 miles with an engine tick. Its not an exhaust leak I know that for sure. It has came up in the last 20,000 miles. I've used motorcraft 5 20 w/ motorcraft filter. I've tried a kreen engine treatment with no change. Heres the description/syptoms:
-Slight clatter for 2-3 seconds upon cold startup (happens very rarely)
-top end ticking that is loudest and most noticable when warm (quieter when motors cold)
-not timing chains/tensioners etc because the noise is coming from the top end and most noticeable on the passenger side.
-at idle the tick is present-when you rev at idle, the noise goes away.
-Driving (or having the engine under any load for that matter) the noise gets louder.
-Anytime I accelerate, tow/haul, go up an incline the noise gets worse
-Sounds like a "whirring" sound from within the dash.
With all that said I am thinking the lash adjusters are getting noisy. I had a certified gm tech that has 40 yrs mechanic experience under his belt and builds prostreet muscle cars on the side look at it. He listened to it to it and that was his diagnosis as well as its not that bad so just live with it. The noise at idle doesn't bother me, its when im driving with the windows down. The noise drives me crazy and is a little annoying to me.
Heres a link to a video of the sound and keep in mind it is much louder now : Triton engine noise/tick - YouTube
Water temperature gauge doesn't work. Assumed the problem was the sensor so bought a new one. Installed it, still nothing registering on the gauge after I know the water is heated up (drove it for 45 minutes, heater blowing hot).
So crossed the ground on the sensor and the gauge shot to the top so gauge is working.
Pulled wiring diagram and that sensor is SUPPOSED to register 79ohms for cold and 8 ohms for hot.. So bought a 10ohm resistor from radio shack and attached the water temp lead to it and the gauge read correctly about 1/8 inch from the H mark on gauge. This confirmed for me that gauge is not at fault.
Next I attached the ohmmeter to the sensor itself, boiled some water, placed the sensor tip into it and it read 86 ohms, in freshly boiled water! So at boiling the sensor isn't anywhere near to tripping the gauge to even start reading cold! So I tested the old sensor that I was replacing and in boiling water it shows 94 ohms?
What am I doing wrong, is there an assumption I am making here in error? I want to conclude the new sensor is bad, but the old sensor reads nearly the same reading under same conditions.So yes maybe they are BOTH bad but that seems to be pushing probability.
If it matters this sensor is the type that is inline from radiator to heater core, not the type that is in the engine block, at some point ford changed their sensor setup but didn't change the schematic drawing. Which doesn't matter the only difference is the one in-line has a ground wire to it rather then grounding off the engine block.
Vehicle is a 97 Ford Ranger with the 2.0 liter engine.
I drive a 2001 Ford F150 4.6L , Miles at 175,000+ (a little more but no more than 176k)
Situation as it happened : Driving home from work for lunch, about halfway home I notice that my Oil Light is on and the Gauge has dropped to below the "L." Engine started making noise, best I can compare it to is to the sound of a diesel engine when it's idle. Immediately pull over after noticing this, shut off engine for about 5 mins, check oil, oil is fine. Turn truck back on, light is off, gauge is normal, and noise isn't as loud as it was before. Drive rest of the way home no problem. After deciding on driving the truck back to work (I know i shouldn't have but I have no other means of transportation, and I work at Autozone so I wanted one of my managers there to check it out) I turn on engine, everything is fine, no oil light, gauge is in the middle of the "H" and "L", only thing wrong was the engine noise, except like earlier it wasn't too loud or shaking the truck. About halfway to work, I come to a stop sign, Oil gauge shoots down below the "L" and the oil light come on.
As soon as that happens engine starts making same loud noise as before (diesel truck idling.) I push the gas to get past the stop sign, and instantly truck loses power in pedal and just shuts off. Make it to side of road, hasn't turned on since. Never had any problems with the truck since I bought it 5 months ago, changed the oil 1 time about 2 months after I bought it. I'm just hoping my engine hasn't seized up on me.
Not sure if this matters, but about 4 days prior to this, truck was making a rattling noise, almost like shaking a can of paint , under the front drivers side, in the suspension. Was told those were probably due to my sway bar link bushings being busted.
After some research on here and other websites as well, I have come to find out that this is pretty common in most Fords? Most people recommend changing the oil pressure switch, and others say it could be the oil pump? Was planning on changing out Oil Pressure Switch, and changing the oil filter/oil , and fuel filter as well. Not sure what else I could do?
Not always & seemingly at random. Just like at startup after battery reconnect.
Most searches come back only with incidents at startup only. Recommendations say battery &/or alternator. Battery is Optima Red that's been in there maybe 6-7 years and all connections are clean & reads 12.48 at rest.
Alt is a AC Delco new unit replaced 20k or so ago & reading 14.24 at idle with or with out any accessory drain on the system or RPM.
Troubling thing is a code for coil misfire on # 5 which put it into limp mode (I erased & so far hasn't returned) & some comm issues with the Inova 1403 that I'm using.
I'm having a problem with my 92 crown vic overheating the radiator and thermostat have been replaced, the temp gauge never goes near the hot range but the engine gets so hot it shuts down while I'm driving. I am a rural mail carrier so I use the car for about 5 hours a day, I have to stop and let the engine cool by opening the hood for about a half hour after driving for 1 1/2 hours. I am not losing any coolant and the fan appears to be working.
View 11 Replies02 6.8 4x4 excursion. When I start the truck cold, the trans temp gauge immediately moves to "running" temp. Not really sure how this happens, I'd figure that if the xducer was trash it would ride all the way high or all the way low. What's happening here? I'd sure like a functional gauge...
