Ford F-150 - 1997-2003 :: 2001 - A/C Overheating Within Minutes?
Jul 9, 2013
'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.

Wife is driving my F-150 and the AC cuts out about 15 minutes into the drive. It may or may not come back on. Getting check engine light code cylinder D. Clear that out and AC again works for 15 minutes. Told I have a vacuum leak. Have the dash apart looking.

I am having overheating problems with my car, I had the car in the shop where they replaced the headgasket, got the head machined, got the radiator rodded out, checked the water pump, replaced the thermostat tried three different ones. The only way they could get it to run without overheating after doing all of this was to run it without a thermostat. I ran it that way for a couple of months, but it is getting colder where I live so I put a new thermostat back in it, now I am having the same problems, it runs somewhat OK while driving, it does not heat up right away maybe after 30 mins or so at city speeds, however at lower speeds it starts to heat up. If i put it in neutral and increase the RPM's the temp gauge will drop down.
After stopping I can feel the hose coming out of the thermostat housing to the radiator and the hose is cool, so for whatever reason the thermostat is not opening, I drilled an 1/8" hole in the thermostat to let any air through that may be in the system. When I refilled the system I opened the bleeder screw that is above the exhaust manifold until antifreeze came out of it then I closed it and filled the rest of the way.

I have a Civic that is overheating after even short drives (ca. 30 mins). Today the heat gauge went up to 3/4 after 20 minutes, and was still rising when I stopped. The radiator fluid is topped up, oil was just changed and is full and not cloudy. No white smoke has been seen out of the tailpipe. The following repairs have already been attempted. New thermostat (replaced 2X), new radiator, timing kit, coolant temp sensors (both), water pump, AC condenser, AC refrigerant. It is still overheating after all that. Why?

This is what its doing... Im starting to feel lost about whats wrong. I start it up and everything is fine. With in about 10 minutes it starts to bubble and spit out a little water then shuts its self off. And the gauge on the dash never reads above 190. And the fans don't come on unless i turn the ac on. And the ac still blows cold. The lower hose stays cold. I just replaced the thermostat and the water pump. But it changed nothing. Im thinking maybe its clogged somewhere. Maybe in the heater core or the radiator.

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.

I have a 2003 F150 4.6l triton v8.... I started over heating yesterday. Got home, let it cool down and found Oil in Coolant. No coolant in oil or transmission fluid. What could be wrong?

1999 F150, 6 cyl. 4.2L, 233,000 miles. My temp gauge went way high on the interstate so I assumed I had a bad thermostat. replaced it with a genuine Ford themostat, added coolant and here's where I'm at.
1. Let it idle up to operating temp. When it was warm, the heater was blowing cold air.
2. Thermostat opened up, top radiator hose was hot and full of coolant, still no heat in cab.
3. Took it for a ride on the hwy. Heat started to work in cab, temp gauge went way up. I slowed down and went home down a side road. Temp gauge went back to normal and stayed there. Only driving about 30 mph.
I don't get why I'm overheating at 60mph. My best guess is I have some sort of obstruction in the cooling system.

I have a 2003 F150 4.6 Triton V8.... My truck started over heating again after replacing the Thermostat and Water Pump later this summer.... Well I checked Coolant and I have Oil in the Coolant. I see Nothing wrong with the Tranny Fluid and see nothing wrong with the Oil.... What could be the problem??????

1998 F150 tries to start on its own. It starts and drives fine, then stop, take key out, wait few minutes then it tries to start on its own. I unhooked the battery cable.

Truck runs cool when driving around town about 177. Get on the highway and the temp goes to about 195, go up a mountain pass she climbs to about 210 and I feel that If I dont back off the gas the truck will overheat because the temp just keeps climbing. Go down the highway again on a flat stretch of highway and it drops to 195, get into town temp drops to 177 and even lower when i just let the truck idle.
Truck has a brand new 195 thermostat, fan clutch is only a month old, water pump is about 2 years old, this truck has had head gasket issues in the past but every year I put in the bars stuff and have not had a problem with it since, I started doing the bars stuff about 4 years ago. This is the stuff you flush the system first with not the pour in stuff. 1997 f150 4.6l

2003 F-150 Supercrew w/4.6 V-8, 2-wheel drive, 219,000 miles and very well maintained. I'm getting an intermittent overheat condition that I can't figure out. Coolant level is good and I just replaced the thermostat. My OBDII app showed it running at a constant 207 degrees (195 thermostat) after the thermostat. Appears to have good pressure at the cap. It ran great for 30 minutes at idle and then did fine for a five mile test drive.
The next day in the morning it overheated within 3 miles of the house (heat was on) and you could smell it. Pulled over and let it sit for 20 minutes and started back up and it stayed constant at 207 all the way to work (11 miles). It sat at work for about 7 hours and ran great all the way home (without heat, with heat, with air cond). Then this morning it did it again, overheating about 3 miles from home. This time I pulled over and shut it off for about three minutes. Turned the key on without starting and the temp was already dropping again. So I started it up and it continued to drop down so I drove to work with no more issues. This afternoon again went home and it never overheated.
I'm expecting it to overheat again in the morning. I'm gonna go live on the OBDII for temps during the drive tomorrow.

I own a 2000 F150 4.2L (I think off the top of my head) v6 XL model. For the past couple of years I've had an issue with overheating. So far I've had the following replaced:
Radiator
Thermostat
Radiator Cap
Water Pump
The intake manifold has been repaired, that was the first item to have some work done to it. The shop I took it to said the coolant hose that runs into the manifold was corroded at the entrance to the manifold. They stated there was no way to actually replace the hose, but they gave me two options:
1. replace the entire manifold or
2. cap the existing entrance port, drill a hole into the manifold next to the port, and run a new hose.
I chose the cheaper option which I suspect is part of the problem. Now to the problem.
I can drive around town all day long no problems even in 100+ degree Oklahoma summer heat. I left it idling on the side of a street for 2 hours during summer and no problems. The moment I get the truck to 55mph it starts to overheat. Not just overheat, but peg completely out in just over a mile after hitting 55mph.
Once I drop the truck down to about 40mph the temp starts to lower, but will fluctuate between normal and 3/4 to max.
What I need to look at? I've been told head gaskets, but there's no leaks and no water in the oil. I've been told to replace the engine, which if I could afford that I could afford a down payment on a new truck. It's a bit frustrating at best.

We had my son's water pump replaced in his 97 F150. It is now occasionally jumping to completely hot. If you turn it off and back on it returns to normal. The power to the engine is cut when it shows to be overheating. The check engine light has now come on.

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.

2003 F150, 5.4 FX4, overdrive light flashes. Took to a shop they said overheating issue, but I don't understand if it is a overheating issue why does I flash at 4 in the morning when I leave for work fter sitting all night and why does it stop when I do over 70 on the highway.

1997 F150, 4.2L V6 200k miles. Truck has been running fine. No CEL, or anything. Stopped and filled up the tank and within 10 minutes of leaving the pump, the CEL came on. Code is P0430.
I drive this truck 60 miles a day. It's shown no signs of any issues until the light came on today. Just curious if some bad gas could cause this or am I in for CAT replacement...

Ok this is actually on my girls car, a 2000 Altima. But i know all newer AC systems work the same. Cus its the same set up as my 98 f150. But the AC will work great for the first 15 mins or so then i notice the pump stops working(not cycling on/off) So i turn it off for 5 mins and then it starts working again and i hear the pump engaging, but it will only work for like 5 mins now. Could it be a bad pressure cycling switch or clogged condenser and gettn the AC too hot and it shuts down.
