Problems overheating. Have replaced thermostat and the housing for it...fan clutch and water pump. Its still overheating especially going uphill when RPM's are higher. How can I check to see if there is a radiator blockage?
View 1 RepliesI have a 2004 Jetta 1.8t. 160k miles. Bought it recently. It's been overheating on me. Mainly on the freeway while having the RPMs higher than the small streets. I don't see any leaks. I'm not losing any coolant. But I do smell burning coolant. I don't see anything smoking though. I changed out the coolant temp sensor. I have a thermostat but haven't gotten to it yet. Just wanted other opinions before moving on. There is some sort of little motor on the radiator with some coolant hose connected to it. When turning off the car, it stays on and buzzes for a good 10-15 minutes before stopping. I'm not sure if that has anything to do with it. I don't even know what that thing is or called.
View 14 RepliesMy wifes 2008 Eddie Bauer Explorer V-6 recently started having an erratic idle and we've started noticing it while at higher RPM's. Its almost as if there is a cylinder that misfires but no engine light is coming on. The car stumbles like it is going to start to die, then the idle jumps up and smooths out. A little while later it does the same thing. The car has I think 74,000 miles on it and has never had the plugs or wires changed. I change out the fuel filter roughly every 24,000 miles and did it recently in the spring. Any places where I should start looking? Could a misfire not trigger the check engine light?
View 3 RepliesI have an 02 Explorer XLT with 164K miles. I am the original owner. Recently the passenger side of the engine compartment has developed an annoying squeak. The pitch is associated to the RPM of the engine. The higher the RPM the higher the pitch of the squeak. It seems to be louder near the underside of the front then near the top. I replace the serpentine Belt Tensioner and that did not fix it. The belt looks good, no cracks or frays, and I sprayed some belt dressing on it but it made no difference. What do you recommend I try next ?
View 8 Replies2002 ranger edge 3.0 5spd. Truck idles perfect, but when you get rolling and higher rpms feels like the engine is missing. loos of power and shakes. I replaced the usual, plugs and wire's, seemed to work for a bit but came back. I cannot get any info on the scanner and have checked all the fuses. I am thinking coil pack but don't understand why it idles perfect and only misses under acceleration. No check engine light on.
View 14 RepliesOn highway, at higher speeds (50-70), I notice that the vehicle's acceleration will pause and the rpms will bounce a bit. Best description I can give is that it feels as if someone were constantly pinching and releasing the gas line. Short revvv...revvv...revvv. The vehicle doesn't lose power. I get where I am going. And it only occurs up at these higher speeds.
View 12 RepliesOk, I have a 95 F150 5.0. It's sat for 6 months with the engine taken apart. I just finished putting everything back together with a new alternator. Well, I pulled a bone-head move and forgot to connect the harness when I fired the truck up. Other than not charging though, it ran fine. When I connected the harness, it began to chirp and shudder at low RPMs and squeal and vibrate at higher RPMs and it over heated VERY QUICKLY.
So hot the case was too hot to touch and the pulley smoked the belt. The engine didn't even have time to get up to operating temperature. I've had the alternator replaced twice, and this last one tested good putting out 14.5 volts. The work I did on the engine was to replace the valve springs, install a direct drive timing gear, replace a spun harmonic balancer, bypass the smog pump because it froze up, new distributor, a new ECU and O2 sensor.
I have a 2002 Ford Explorer and besides the seemingly oh-so-common annoying crack in the tail gate, I have another issue I consider to be major. Recently, on a short trip to the store, I hit an incline in the road of a slight degree. At this point I noticed the RPMs going wildly up and down and ultimately the truck died. I tested this out on a few drives and what I've noticed is that if I'm on a flat surface, the truck seems to be okay. OR if I do hit an incline, either lifting of the gas or powering through it seems to work...although neither of which is a long-term solution. I just lost my job a couple weeks ago and the idea of taking it to a mechanic scares me as I'm very limited on savings. I don't really know where to start.
View 6 RepliesMy 4.65L V8 Explorer has an issue in low gear - RPMS rev high but car doesn't shift up.. eventually "catches" with a jerk but the OD Light started flashing and the Systems Screen reads Check Transmission. Light goes out and message goes away after turning car off and restarting. Had one Tech look at it - he said second gear is toast and need full transmission rebuild. Another Ford Tech looked and could just be solenoid needing replacement and advised to have a transmission service (not a flush) done....
View 2 RepliesI think it's possessed! My sisters vehicle, a 2002 Explorer with a 4.0 V-6, automatic, 2 wheel drive will just shut off. At first it acted like it would vapor lock. But it would start right away. then the a while later, (several months), it got where it would drop rpms and the engine shudders, sometimes not dying.
When this first started, the throttle body was cleaned, a new air filter installed, fuel pressure checked. Everything checked out and for a few days it ran fine. Then it started all over again. There has never been a code thrown. All of this goes on only when the ambient temp is above 70 deg.'s. below 70 deg.'s it runs perfect.
Last week it went to the mechanic again and a new crank speed sensor, fuel pump, and diagnostic done. He could not find anything wrong any where. Took it for a test drive and it dyed on the mechanic. Still no codes. What the problem might be? Every Mechanic that has looked at it has gave up, one even saying, " it's possessed."
I have a 2006 F550 mini bus, that I just had the head studs done, egr delete and air intake changed. Last night we took it out for a run to test it since we just installed a new fan clutch. We can here the fan kicking on and off. The problem is, we drove it say 60 miles, up and down a mountain, had no issues. We got out and ate for about an hour, and then drove it back the same way. This time on a slight upgrade my check gauges came on, and I seen the temp rising. I let off the fuel, and it dropped back down. So the rest of the way home I was easy on the fuel and made it back with out heating up again.
Today, we took it for a ride and at idle before we left the ECT was 172, and EOT 170, as we drove I watched the temps. Climbing up a fairly steep mountain, we were doing about 65mph, for about a 5 mile climb. During the climb my ECT was 201 and EOT 226, at the hottest point it was ECT 204 and the EOT was 226.
I am assuming it could be a possible water pump and or oil cooler. Reason I am thinking the water pump, is because after it over heated, I noticed if I let off the fuel quick after running I would hear a noise like a puffing sound. It was the coolant shooting out of the degas bottle. It did this several times when letting off the fuel quick, which I think was the pump was allowing the coolant to be pushed back in from the heat.
I already ordered a new pump, which if bad could also cause the oil not to cool as the pump is not pushing enough coolant? (Also I only lose coolant if it gets to hot)...
I have a 2001 excursion 7.3 4x4 with the 6.0L trans cooler. It is over heating when heavy, uphill towing is under way. I am guessing that my computer has been reprogramed at some point and more fuel is being injected than the radiator is designed to cool. I know my trans cooler is clean. I have tried cleaning the radiator and intercooler with a garden hose. I am considering a hood scoop or some sort of vents in the hood. When it over heats I turn on the heater and open the hood and the engine temps drop in just a few minutes so I believe that the engine needs more cooling or I need to slow down a bit on hills. Any other cheap fixes to get more air in to cool things under the hood more?
View 1 RepliesI found recently that my 04' Prius' engine easily goes higher rev than before (based on engine sound pitch). It happens mainly when cold start, go up hill. After warmed up and on flat road, it goes back to normal. Overall, still in great condition at 211K. MPG stays at 46 on meter when temp is around 45F with 50% highway drive at 100 miles/day. I suspect the serpentine belt slippery or something. What do you think? I think the belt is original. I bought it used at 104K.
View 4 RepliesMy Subaru want to stall when it shifts from a higher to a lower gear when driving up a grade/hill. Also does the same thing when pulling out from a stop sign or traffic light. You need to pump the accelerator to get it going.
View 1 RepliesMy ac seems to get cooler at higher rpms. I looked online and it appears to be the orifice tube...
View 3 RepliesI have a 05 Sprinter 6 cyl gas HD that overheats a little at highway speeds over 60mph and then the rpm is limited so the van slows down to the 50 mph range even if I floor the gas peddle, I usually pull over turn off the engine and let it cool down for an hour and resume the trip. It only does that when going up the mountains while the van is loaded or on extremely long trips. Ive taken it to two mechanics both could not reproduce the problem. It has 250k...
View 6 RepliesI have a 2006 Ford F150, king ranch, 4x4, super crew 135k miles. I bought the truck and shortly after noticed the miss under a load at 40-60 mph while in OD, or at higher RPMs at WOT, but never a CEL. Well 3 months went by and I couldn't take it anymore so with lots of research I decided to change the plugs. Ran seafoam through 2 tanks of fuel prior to this job to break up the carbon in hopes of none of the plugs breaking.
All 8 plugs came out with no issue and I replaced them with the Motocraft SP 515s (old ones were very nasty and brittle, most likely the original). I put copper anti seize on the end that goes through the channel in the head, however none got on the end near the electrode, and also on the threads. Put it all back together and it had the worse misfire an pretty much not drivable....flashing CEL and codes p0308, p0355, p0356. So I decided to buy 8 new coils as well, got all 8 of them on and now the truck is drivable but the miss is still there (no CEL).
Feels like maybe just one cylinder and I believe I got it pin pointed to cylinder 8. I put a vacuum gauge on it and unplugged the injectors 1 at a time and cylinder 8 is the only one that there is no change while unplugged. So I switched out the coil thinking maybe I got a bad one, still does it. My COP electrical plug has 12v Constant and also confirmed with an led it is getting signal. The injector is ticking or pulsing as i confirmed with a mechanic stethoscope. What am I missing????? Today when I get off I plan pulling the spark plug, checking for carbon tracking, check compression, check actual visual spark, and pull and clean the injector.
1999 F350 7.3 Super Duty surges when going uphill with a load. The only time we drive it is when towing the horse trailer - also has a camper on.
The truck doesn't physically surge, just the RPM gauge goes up and down and along with it a humming noise.
Also, What conditions should I engage the towing button on the end of the gear shift? I've heard several answers. Should it be engaged when towing or off?
My car leaks water/coolant when off, the other day it was overheating but it had plenty of water in it, it seems to struggle when going up hill, also when i use blinkers sometimes it makes a loud buzzing noise and wont work, happens sporadically...

View 5 RepliesI have a 03 F250SD with ~145,000 miles on the 5.4L. Just recently I have been having what seems to be a miss, or possibly a dead cylinder. I thought it might be a dirty MAF, but I cleaned it and have the same problem. The miss is more noticeable at the higher RPMs. I am checking the plugs today. So any solution? I refuse to take her to the shop and having another man up in her manifold.
