Ford - Ranger :: 2000 - Overheating While A/C Is On - Replaced The Radiator Cap
Aug 8, 2011
For a while now I've been having issues with my truck overheating. Generally when I slow down, come to a stop, after driving a while. The other I replaced the radiator cap, as coolant was bubbling out after driving far. Thermostat was replaced. Radiator was flushed today as there was some rusty color build up. Added engine oil as it was VERY low the other day. So far I'm still getting the overheating issues and it seems to happen more so when I run my AC. I've noticed no significant leaking from anywhere else after replacing the cap. I'm thinking of either the water pump or the fan? But I dont know how to know for sure and I dont want to replace parts that I dont have to as a waterpump alone is $50-60.

I have a 76 f250/460 engine. I have replaced the hoses, belts, water pump, fan clutch, flowed the radiator and it still overheats.

Bought this truck at auction a few days ago. Started drive home and noticed temp gauge almost pegged full hot. Stopped and left it and pickup up later that day with trailer. Got home and started and ran it. Will not overheat at idle. Gauge fluctuates between full cold and 1/2 at idle. Rev up and temp drops to full cold. Drive around town under 35 and it stays between 1/2 and 3/4. Get on the highway and Pegs full hot. Replace thermostat and flushed system. Lots of rusty water and chunks of rust/mud poured out.
Upper rad hose is firm and hot. Lower rad hose is warm soft. Bypassed heater core and still over heats. I can run water hose from top hole on radiator and water crosses threw radiator and pours out the bottom so I don't think it's clogged. It's not the head gasket, I have no smoke, no milky oil and no oil in coolant. Fan clutch seems fine, I can spin it with the engine off and feel resistance. Truck hasnt boiled over while running hot so the gauge may be wrong. If it means anything the truck runs very rough and pulled up a misfire on cylinder #1 and had a iac code.

I have a 2000 Ex with 252,000 miles. Where it is extremely hilly (Ozark Mountains). I tow a 6400 lb travel trailer. What I am having problems with is the Ex is running extremely hot when towing and climbing hills. Not in the red, but damn close. No problems what so ever when not towing. No problems when towing on level ground. I know the Ex is working hard, but I want to keep it running cooler. I have flushed the radiator literally 20 times and have done 2 chemical flushes. Is it time to just replace the radiator? How many passes does the stock radiator have? What about a bigger water pump? I have the 5.4 motor, which I love so no bashing my little V8. It has all the power I need. I don't need to climb hills doing 90mph.

My 2000 Accent with 164,000km is not overheating but is dumping coolant into the reservoir so that the radiator is about a quart low. I did have a few problems with it overheating in the past month, but that was solved by thermostat removal (always above 80F here). I stopped before the overheats reached the redline and allowed the engine to cool before continuing, no known adverse performance during the overheats. No water in oil.
Failed troubleshooting:
Drained and replaced coolant x3
New radiator cap
* No thermostat.

I replaced a cracked radiator with a new one on my 2000 model B2500 a coupla' days ago, guessing at the refill, as I just got the truck and don't have a manual. Guestimate was pretty close, but I got some weirdness from the temp gauge for a bit. Temp gauge read cold (even though it was maybe sixty degrees outside) after idling for quite a bit, but would rise to operating temp if I ran the RPM's up a bit, then fall back to cold when I let it drop back down to idle.....never rose to above normal operating temperature, though.
I took a short drive down the road, stayed at normal temp, but dropped back down to cold when I parked it. Taking a peek under the hood, had air blowing out into the resevoir, bubbling like bathtub farts. All appears to be normal today, but I've gotta' take this truck for a roadtrip in a coupla' days and would like to make sure I ain't missed a step that'll send me hikin'.
What is the process of burping the radiator so's I can be sure it's all good?

My Camry seems to be overheating. When I'm driving the gauge maintains and reads 6/10, when the engine is idling, it goes upto 8/10, radiator fans kick in and then temperature goes down to 6/10 and keeps cycling over a period of 5 mins.
It's got 100K miles, water pump has not been replaced yet.
I checked the hose temperature; top hose 210 F, bottom hose 192, fans kick in when top hose is around 215 F.
I checked the engine temperature where the sender is installed and it was reading 205 F. Coolant level is OK. I burped the system. Previous owner told me, he had thermostat replaced by dealer.

I have a 2000 Ranger, V6 4L, and I believe my head gasket is blown, my radiator fluid goes straight to the oil pan. It has probably been leaking for a while, I did not realize it was leaking internally, I had been adding coolant for a few months but thought it was my radiator leaking because it had a crack in the housing, so I had that changed, but then a few weeks after that It gave out. I drained, and flushed the engine twice, and just parked it. My question is, should I just have the head gasket changed, or does it need a new engine because it had been leaking for a while and not sure what kind of damage it has done internally.

92 Toyota Pickup (22RE auto). New block, rebuilt head, new water pump at 300k about a year ago. Sounds strange I know but that's what seems to have happened. Ive never been able to get heat from the truck since Ive owned it so Ive been trying to fix that. I flushed the coolant out and replaced the tstat. I brought the car to a mechanic and he put a pressure tester on the cooling system and he said it wasn't holding any pressure. He also pulled off the heater core inlet hose with the truck running and no coolant was coming out. He thought there was a blockage somewhere but how to fix it. I figured I might as well try replacing the old radiator cap with a new one so I did. Once I did this, the first time the truck went out, it overheated and the radiator crimped upper seam (on the plastic) burst outward.So all in all...something is wrong.

156,000 miles, I've been pulling a 21ft bass boat in the summer for years with no issues. Now on hot days (over 78 degrees) it is over heating. Can't use AC and need to slow down to 60 mph in-order to cool her down. Never have flushed the radiator but I'm wondering if getting it flushed is a waste of time and if I should just proceed to replacing the radiator? For a couple of years now I can hear a roaring sound (like a jet engine) on really hot days, when I start out driving. Could this be a cooling fan? Seems like the power is restricted during these times. Really need to increase throttle to get going?

I successfully replaced the radiator on my 2003 Ford excursion (LMD, V10, gas). I filled her up with coolant and started her and turned on the air full blast.
Noticed though that she is now leaking somewhere between the engine and the transmission pan.Where and what to check?

I had to replace the temp gauge in my 1996 Explorer. I also replaced the sending unit. Now, it is overheating, badly. I replaced the thermostat, twice. Filled the coolant and removed the air in the system. It seems to get good water flow, and there are no coolant leaks. The radiator looks clean, and the cap looks ok. But, as soon as the engine warms up, it goes right past the midline on the gauge all the way to hot - at idle. It gets worse if I drive it. I have grounded the gauge and it seems to be working fine. What could the problem be?

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.

My 1992 Nissan Primera 2.0 slx is overheating, probably on its last legs. First time this happened the radiator overflow tank seemed low so I topped it up with glycerol and added some leak plugger to the radiator for good measure. The car drove just fine for 20-30km then it happened again. At the same time, and I don't know if this is relevant, the windscreen defroster, which should bleed warm engine air, now only gives cold.

Ok, I just bought myself some problems in the form of a '93 Celica GTS. (5S-FE)
Well, alright, that's a little dramatic. it just overheats. but here's my issue. it's got a new water pump, new radiator, and is still overheating. The guy I bought from says it's in the block, cuased by an attempt to plug a radiator leak with stop leak. He said it just had a minor leak in the radiator, so he put stop leak in it, and after that it started overheating. he's replaced the thermostat, water pump, and radiator since then.
My first question is, could he (and I) be overlooking something? could there be a clog somewhere easier to access? and then if there isn't, how should I go about cleaning out the block? are there areas I should check? anything I should do to try to unclog it? my current plan is to put cooling system flush in (he has some) and drive it home (about 55min. drive) with the flush in it, then empty it and hope for the best.

Will start with the back story, i have a 2007 G6 V6 that had a slow leak in the radiator. I kept it full and it only went higher than normal once but i noticed it right away and didn't let the needle peg at hot so I've kept it full, checking it every time I went somewhere. the other day on my way to work the needle pegged at hot and the temp light came on so i pulled over right away and shut the car off and let it cool for an hour and added some more coolant. started it up again and the temp stayed normal for a minute so i tried to get it back to the house when the needle pegged, i lost power and the check engine light came on. i stopped the car and called a tow and while waiting on the tow truck my battery died and all i had running was the hazards. the only thing I noticed was the leak in the radiator had gotten worse.
After I got it home and let it sit for 5-6 hours i got a jump from my neighbor and I noticed I wasn't getting any circulation, the reservoir was still full, the check engine light came on and stayed on, and within a minute or two the temp was rising fast so i shut it off and haven't touched it since except to check the oil which looks, smells, and feels fine and is at the proper level and didn't see any oil floating around the overflow tank. and while the car was hot I didn't see any smoke or steam coming from anywhere aside from the leak in the radiator, the water pump pulley was spinning fine, no whining or whirring sounds. i did notice that the plastic piece where the metal overflow line attaches to the engine was badly cracked but wasn't leaking.
I'm thinking maybe the water pump went out and/or the thermostat is stuck closed and caused the overheating issue. as far as the check engine light goes, could that cracked plastic piece cause the check engine light to stay on?not sure if there's a sensor involved in that or not. or could it be the low coolant sensor causing it as the block has no coolant in it?

I own a 2003 Saturn Ion I.
Recently I noticed that the fan on the radiator does not function, resulting in overheating when using the AC. I have tested the electrical wire leading into the fan motor and found that it is putting out 14.4 volts, indicating that the wire is functioning properly and that all fuses are intact. I also hand spun the fan to see if it would turn without resistance, which it did, indicating that the motor is not jammed.
These tests lead me to believe that I may need to purchase a new fan unit and install it. Additionally I have found that there is a dual fan option for my vehicle, and I was wondering if I should purchase that instead of the standard one fan?

I changed the radiator and thermostat, changed the coolant, and my fans work. however, whenever i take the car for a short drive, the temp goes up. I stop the car and shut it off, it steams near th coolant tank. it sounds like its almost boiling..
