Ford F-150 - 1997-2003 :: V6 Slowly Overheating In Hot Weather


Jul 2, 2007

I have an 1997 F150/4.2 V6/220,000 miles/4x2. During hot weather (over 90F) the engine slowly overheats. While driving on the interstate (from Indy to Fort Wayne), the coolant temperature shows normal on the gauge. Slowly the temperature gauge creeps up to close to the red area. I am running the A/C.

When I switch the heater on and the heater fan at max, the temperature gauge drops pretty quickly to a normal range. I switch off the heater and the A/C back on, then it takes 30 minutes for the temperature gauge to start rising again.

When I open the hood when the gauge shows close to the red area, the upper coolant hose has a lot of pressure (can not squeeze it), which would mean that the thermostat is open and the water pump is working. Also the fan is running fast.

The coolant was changed out a few weeks ago and the coolant level is at normal level when the engine is cold. At lower ambient temperatures, there is no overheating. I am puzzled what the problem can be. I am thinking of a restricted coolant flow.

Ford F-150 - 1997-2003 :: Truck Struggles In Warmer Weather But Not Overheating

I've got a 2001 F150 and lately, since the weather has warmed up, I've had a problem. After a few minutes on the road, the engine seems to be lacking power and is running hard. It also seems to shake a bit too. It's not overheating and the gauges don't show signs of high temp. My drive to work is 40 minutes and by the last 10 or 15 minutes it seems to be OK. ... A month or so ago when the weather was cold, I had problems keeping coolant due to leaks but that problem seems to have diminished. I don't know if any of that is connected to the original problem or not.

Ford F-150 - 1997-2003 :: 1998 - Can A Heater Core Slowly Go Bad

I have 1998 F-150 and the heater core was replaced 18 months ago. All was going well until about 2 weeks ago I noticed under heavy acceleration I would smell antifreeze. The smell would clear up and would not re appear for a day or so. Finally the other day when it was 8 outside I got in the truck and got about 5 miles from the house started up a hill and it was like a fog machine was mounted behind my dash the windows fogged up almost immediately so I figured great the core went bad again. Now the temperature has warmed up the last couple of days and there is nothing no fog in the cab the heater works fine just an occasional slight smell of antifreeze. Before I go through the trouble of tearing out the dash is there anything I should check I already checked the connections on the firewall and they were fine.

Ford F-150 - 1997-2003 :: Parasitic Draw / Battery Is Slowly Discharging

With the hood open and the hood light bulb pulled out, measured the parasitic draw on their truck? I checked mine because it appears my battery is slowly discharging if the truck sits 3 or 4 days. I got 0.24 amps which seems in line with running the clock memory and the computer. I have a feeling the battery is shot even though it is only 3 years old. When I bought the truck it had a ton of yellow fuzz on the terminals. That is cleaned up and with it running I get about 14.35 volts at idle so it is charging. 0.24 draw??

Ford F-150 - 1997-2003 :: Brake Pedal Slowly Going To The Floor While At A Red Light

I have a 2000 SCrew KR F150. A couple of weeks ago I noticed the brake pedal was slowly going to the floor while at a red light. I pulled over and popped the hood checked the fluid reservoir. It was full, so obviously no wheel cylinder issues or fluid loss. I haven't had a chance to tear into it yet.

Have a '02 f150 and thinking the heater core slowly dieing. Have noticed for several weeks a nice line of water leaking onto the passenger side floor. Do you have to take off the entire dash to get to it? Will be doing replacement myself as the dealer or shop would probably kill me on labor.

Ford F-150 - 1997-2003 :: 1999 - Rough / Jiggly Ride Even When Moving Very Slowly

Here is the critical info...1999 F-150 2wd supercab, 4.6 litre, Automatic, 138,000 mi

Recently, I had the upper control arms, upper ball joints, and lower ball joints replaced. They also did an alignment. Since then, the truck has had what seems to be a rough, jiggly ride. I can feel every little imperfection in the road, even when moving very slowly. I've also noticed that my doors sometimes rattle now (they didn't before the work was done). On the highway, sometimes it seems that a tire will get into a bouncing condition which can continue for quit awhile. It is also harder to keep the truck centered in the lane.

I went back to the same place that did the work and told them to double check everything, (which they did, found nothing wrong).

To try to fix this, I have...
replaced the shocks (new ones are bilstein)
balanced the tires
rotated the tires
checked air pressure (32 psi)

I don't know if the following facts have anything to do with anything, but... When I look at the upper control arm attachment points, there is a metal plate that is (I'm told) to keep the camber in the factory setting. This plate was removed on one side to adjust the camber away from the factory setting. Also, I don't see how the castor is controlled? Is there an adjustment for that. Can castor be to blame for any of this? Can cheap parts (control arm, ball joints) be to blame?

Ford F-150 - 1997-2003 :: Rough Shifting In Cold Weather

I have a 1999 Ford F-150 XLT, with the 5.4 and a 4spd auto. 172,XXX miles on the clock and i have owned it starting on April of 2014.

Tonight driving home from work, it took some time on the highway (4 miles) to shift into top gear. When you lift off the gas pedal after reaching the speed limit, normally the truck will shift from 3rd to 4th no problem. When I let off the pedal, there was no gear change.

It took sometime for it to shift up. When downshifting on the exit ramp, there was nothing abnormal. Where I live it is 19 Degrees Fahrenheit and this is the beginning of the cold snap that will last well into mid-January of next year.

Ford F-150 - 1997-2003 :: Intermittent Misfire When Weather Getting Hotter

Ok I've been getting a intermittent misfire on my truck for soem time now. It ran great all winter but now its getting hotter it intermittently misses. Last summer I replaced all the coils. And the coil inquestion now was replaced since last summer with Motor Craft Coil. I have red the check Engine Codes a d here is the freeze Fram data

DTC :P0351
Fuel System I : Closed Loop
Calculated Load: 71.37%
Engine Coolent temp: 199.4 F
Short Term Fuel Trim Bank 1 : 3.91%
Long Term Fuel Trim Bank 1: 0.78%
Short term Fuel Trim Bank 2: 6.25%
Long Term Fuel Trim Bank 2: 0.78%
Engine RPM :1613.25
Vehicle Speed Sensor: 4.35 MPH

What might be my problem? Since The Short Tem Fuel trim from bank 1 and Bank two are vastly different could that mean my fuel injector is not working correctly?

Ford F-150 - 1997-2003 :: Battery Maintainer In Cold Weather?

A problem with having a 12 volt battery maintainer hooked up to your truck when not being used for a few weeks? In this cold weather the new battery keeps drawing down while not in use and is slow to turn over after 1 1/2 weeks or so? I think the maintainers charge at about 1.5 amps. I wonder if that can keep up with all the parasitic draws: PCM, radio presets & clock, remote door lock system, and factory security system and keep the battery topped off as well?

Also, is there any problem with putting a charge on a battery when the cables are still hooked up to the trucks electrical system with either a maintainer or a full size charger, Example: screwing up the PCM?

Ford F-150 - 1997-2003 :: Pedal Slowly Begins To Fade Towards Floorboard When Holding The Brakes

I have a 2003 F-150 4x4 with cruise control and 4-wheel disc. When I am at a stop light for a while, when holding the brakes, the pedal slowly begins to fade towards the floorboard. I have replace two master cylinders, the original and a reman and then put on a new Motorcraft one...all providing the same problem. I have been told by dealerships that it is my imagination or that this is a "normal" problem. Having my truck roll at a stop light while the brakes are applied is not normal.

Ford F-150 - 1997-2003 :: 2001 - Surges In Hot Weather And Losing Power

2001 F150! It does this weird little surge, burping and farting away...but only in ambient heat. The engine never gets hot, it never over heats. What have we done? A full tuneup with new plugs and boots, oil change, new air filter, gas filter. It did it again...took it back in and had the fuel pressure checked, fuel injectors are fine...it can't be the fuel pump, it runs great unless it is hot weather. It has twice blown the P0171 system lean bank 1 code and has gone away after the tuneup and again after the new o2 sensor. It runs great, except in hot weather, starts surging and losing power...

Ford F-150 - 1997-2003 :: Hard Start After Sitting In Hot Weather - Code P0443

I have a 1997 f-150, V-6 absolutely base model, a shade under 80,000 miles. I'm the second owner, and the truck was previously garaged most of the time but now sits out in the driveway. The truck has developed an issue where it will be increasingly hard to start (crank crank crank, intermittent cough) after it sits out in hot weather, which is a problem here in Southern California. When the problem is really bad, it can take all day to get it started (try, wait a bit, try again, etc.). When it does finally catch, it sometimes backfires, idles rough for a few seconds then runs like a champ. I can turn it off and restart it immediately, I can let it sit for an hour or three and restart it, but if it sits out in hot weather it gets increasingly hard to start.

I've scoured various forums, and I've tried every solution I can find. Cycling the key to get fuel in the rail, opening the hood to cool off the engine cavity, trying to start it before it gets hot outside, etc. The truck *is* throwing code p0443, and scouring other forums I think that's either the evap canister purge valve, which my last mechanic replaced, or possibly the charcoal canister, which has not been replaced, but I don't know if that could be contributing (the truck was throwing that code before the hard start developed).

Ford F-150 - 1997-2003 :: Vibration / Grinding Sound Coming From Truck When Moving Slowly And Making Turns

I have a 2003 Ford F150 with a 5.4V8 Triton 4X4. The truck is about to roll over 200K here soon. I am feeling/hearing a vibration/grinding sound coming from the truck when I am moving slowly and making turns, either left or right turns. Seems to happen more so on left hand turns. I have changed all power train fluids and filter, and still does it. I do not feel or notice the vibration/grinding when I am going straight or at highway speeds. It is only when I am moving from a stop and making turns. How to diagnose, find out, repair, fix this issue?

Ford F-150 - 1997-2003 :: 2001 - A/C Overheating Within Minutes?

'01 F150 XLT 5.4L EFI 207,000 miles

I've had this truck since '03 @ 45,000 mi and have loved it ever since. It hasn't failed me yet, until now. Living in TX with no A/C is the pits,

He first replaced the large hose assembly (with a non Motorcraft part) due to a pinhole then recharged the system. It cooled great until the pressure pop off valve (or whatever it's called) blew all the freon out.

His first suspicion was the fan clutch, which was replaced with a motorcraft fan clutch. Next he used his a/c machine to evacuate/flush/recharge the system - problem persisted. Lastly, he cleaned the radiator and condenser fins and recharged again. The system still overheated and lost the freon.

While the freon is in the system it cools like never before but after driving it, parking for a while, then re-starting it overheats within minutes.
