69 T-bird Engine Overheating When Get On Highway
Apr 23, 2012
I have a '69 T-bird. The engine temperature is always normal when I'm driving around the city. When I get on the highway, though, and go 80 mph for just 5 minutes, my engine overheats. I replaced the thermostat but that didn't fix the problem. The radiator and water pump work fine (as far as the mechanics can tell). We checked the engine, too. Compression is good on all cylinders. Also, it passed a block test (there isn't any oil in the coolant).

My 2002 VW Jetta GLS 1.8T 5-Speed is over heating
Car is still over heating after replacing the following:
- Head gasket
- Coolant fan module
- Geba Metal Prop Water pump
- Full timing belt kit
- coolant fan switch in Radiator
- Bleed the system of all air blow hot air
So Driving the car around town is ok, doesn't over heat, but as soon as I take it on a highway it over heats. I drove it 50 kms out of the city and it over heated, let it cool down and added water. got it back home. Oil light flashed on as I pulled into driveway, turned it off right away. no external oil leaks. Checked coolant, Oil in coolant. also the coolant was boiling, the level was raising up and lowering. I have been reading the forums for a few hours and the oil in the coolant sounds like the oil cooler gasket. Ok so the fans are running and it still over heats. The old metal propeller water pump was very hard to turn so I replaced it with a Geba Metal water pump. no leaks at water pump. Could it be possible that the Oil cooler was causing air to leak into the cooling system causing the coolant to boil? And then when the oil cooler "o-ring" finally failed it dumped oil into the coolant?

Alright, car's overheating, but generally not at under ~55mph or so. When I hit the highway and accelerate, the thermostat climbs and hovers 3/4s of the way to red. But only sometimes. Sometimes, often when I'm going down a hill, it will swings down to normal. Once it's gotten hot, if I take it off the highway and am idling or driving in the 15-40mph range, the temp gauge will spike. But only sometimes. Sometimes I'll hear the fans kick in while it's idling/overheating. The temperature will go back to normal, and then rise again and stay there or spike (seemingly randomly). It's never reached all the way to the red, but it toes the line. And I take the darn thing into the shop and it refuses to overheat.
I've taken the radiator reservoir out and there seems to be green fluid (antifreeze/coolant?) in the water (have flushed it repeatedly)...and over the course of several weeks, the water level itself will go down. Both fans and the thermostat have been replaced in the last 6 months. Additionally, the timing belt and serpentine belt have been replaced within 5 months, as have affected pistons.((S/N--RPMs are really....low? ~2500 @ 75mph? but don't seem to correlate w/temperature. would they effect it?)
I took it into my shop and they said "we ran all the tests and couldn't find anything wrong." Cool? I'm at a loss..

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 2001 Subaru Outback Limited with 135K miles on it. In the last year, I had two complete head jobs (the second because the new water pump failed while on the highway). In addition, I have had multiple water pumps, lots of thermostats and a new radiator installed. The last thermostat is an OEM. The car had been running fine for about a month and now overheats after about 30-40 minutes of combined, but mostly highway driving. At first, the gauge would rise to about 3/4 and then drop after about ten seconds, but now it goes to almost red and drops to 3/4. If I blast the heat, it will drop pretty fast. My mechanic told me that while diagnosing an earlier overheat issue (just before the good period), he noticed that the gauge would rise, but the computer temp would remain stable. He tried a new sensor, but said it made no difference, so he returned it. What is left to replace?

I had overheating problem on the highway. Towed car to Automotive Clinic - They said I needed new radiator and hoses, so I installed. Couple weeks later, overheats again, this time said I need new head gasket, so I go ahead. Soon as I get back, my car overheats AGAIN. Now back in the shop, and they told me the head gasket blew again...they have taken all apart, and now say they can't find out whats wrong. The coolant is leaking, but they don't know why...it failed hydrocarbon testing. What can it be?

I've owned this Civic since new, now at 153K miles. This is a recurring problem that I've been having for over a year. First symptom was there would be no heat coming from the heater at idle with the motor well warmed up. Add some rpm's and the heat returned. The reason was not enough coolant in the system, filled up radiator and all OK. Then it happened again and there is coolant in the overflow tank, but pull the radiator cap and no fluid under cap. Fill radiator and all OK, but it kept happening. I replaced the OEM radiator cap with a new "Slant" brand for an '03 Civic. No better, no worse.
Last week I had a significant overheating event while on a highway. I pulled into a "Dollar Store" parking lot, went into the store and bought 50/50 coolant and shop rags and let the car cool off for 30 min. When I pulled the cap, it was a steamy mess and I let it cool some more. Eventually I put in the coolant and finished up the drive with no more overheating. The overflow coolant container was at the "full" mark all during the overheating event.
At this point I took it to my trusted mechanic. My mechanic determined that the overflow tank was clogged and he blew out the line. So, I hoped all was fixed. But I don't think so. With the car cool this morning I pulled the radiator cap and got a swish noise indicating some pressure release. The level of coolant in the overflow contain hasn't moved. It still seems coolant is not being pulled from the overflow container back in to the radiator when the car cools off. I blew into the radiator top (where the cap goes) and that did produce lots of bubbles in the overflow tank. It seems it is no longer plugged - but why isn't the coolant behaving properly?

I have a honda civic 2000 and recently I noticed that it overheat only after exiting a long drive on highway. The car does not overheat for my normal daily commutes (within the city).
I tried the following:
- Checked coolant on bot radiator and overflow tank.
- Changed the thermostat- No leak on the ground in the garage where I parked the car overnight
- No noise to lead to an eventual issue with water pump
- Radiator fan is kicking ok
- Had a mechanic do the chemical test for the head gasket: negatif
- Found that there is air in the cooling system:tried to burp the system 2 times but air is still in the coolant system. Not sure where its coming from !!?? Might be that this could be causing the overheating ?
- Found a crack on the manifold and changed the manifold then tried to get rid of the air (burping the system): no success. The air is still not removed completely.
- Changed the radiator cap.
What can I do next to diagnose the overheating condition that happens only after exiting long drive highway?

2003 Hyundai Elantra.
Driving on the highway and thought I heard a belt squeal. Looked at temp gauge, overheating in the red. Stopped car. Antifreeze on passenger side sprayed around, hard to tell from where.
Waiting a while, put a good amount of water in it as there seemed to be no anti-freeze left. Drove a bit more and it started going up on temp gauge. Pulled off highway on an exit, temp gauge went back down before I could pull over.
So I continued on the highway. The temp gauge would go back up to 3/4, then I'd put it in neutral to cost to a better place to stop, and the gauge would go back to halfway.. continued this for several miles to get home. Never overheated again, but kept getting "hot"(3/4) and dropping back down to normal (1/2)...

I have a 1994 F-250 that we have changed the thermostat, radiator, water pump, cap, hoses, and installed a spring fan. New heads. Hot heat in the heater. It runs normal at highway speed for around 10 or 12 miles and gets hot. pull up and idle and the temp retracts. Even the block has been blown thru. What could possibly be the problem?

My '97 Honda Civic overheats when driven at high speed on the highway for more than an hour. I've changed the thermostat and the radiator fan, but it still does it.

I drive a 2000 Dodge Dakota Sport w/ 4.7L V8 engine. I have been dealing with an overheating problem for about 6 months now and have nearly exhausted all hope of correcting the issue. It has been in the shop on 4 separate occasions and seen 2 different mechanics. The radiator has been replaced, the thermostat and thermostat housing have been replaced, the radiator fan works properly, hoses have been replaced and no subsequent leak has been found by either mechanic, they haven't mentioned the possibility of a blown Head Gasket (nor has the typical "milky residue," shown up in my oil cap). Each time I got it back from the shop the problem was fixed for about two weeks, then returned and slowly got worse.
It overheats in idle (with the fan running), on the highway at high speeds, and while driving slow. Sometimes it only gets about 3/4th to the red (usually when its cool at night) and sometimes it will hover just below the red; while I'm doing everything I can to keep it from hitting red (defrost on, revving engine). Some days it takes a little while to get hot and some days it happens very quickly. I'm tired of sinking money into the vehicle but as a recent grad I don't have the money for a new truck at this point. Suggestions included heater core clogged, water pump gone bad, fan clutch.

I took it in to repair shop and they checked all belts and said its all good but I still hear noise. Sure hope it's not the transmission as it only has 44K miles. Car is Sentra 1.8 - 2006.

I went out to our driveway (just a couple of hours ago) where my Ex was parked and I heard some bird chirping coming from under the truck. I looked at the Ex and I saw these 4 little birds right under the rear axle flapping around on the driveway. I immediately picked them up and ran inside the house and handed them over to my wife.
I went back outside and looked the underside of the Ex to see where the birds came from. Here's where they nested just above the rear axle.
Here they are after getting feed by my wife with some pureed meat (per google) since we really did not know what to feed them. They ate like crazy even had some bowel movement after 10 -15 minutes. We tried calling the local Animal Control but they are close on Sundays. We will try again tomorrow and for the mean time we'll try to keep these guys warm, fed and comfy. Per research they need to eat every 15 -30 minutes.
That's their actual nest I pulled out from the truck. I wonder how long have these birds been living inside the Ex? You see the Ex gets driven only on weekends sometimes longer.

I have a 2003 f150 with a 4.2 v6 2wd and about 116 on the clock.
It has this annoying, faint squeek whenever i hit bumps in the road. Sort of sounds like bird chirps. I cannot reproduce it if I bounce on it while parked.
One rainy day I tried to show a friend and it would not make the sound it seemed. Therefore I think its exterior, although it almost sounds inside.
Today I sprayed down all the rubber joints under the front end with silicone spray. It still squeaked while driving afterwards.
I should note that a ford dealer claimed the ball joints were worn and needed to be replaced. Although, would a ball joint make bird chirp type squeaks while driving at most speeds (20mph - highway speeds)? It does not intensify or change at any particular speed.
My understanding is that a bad ball joint would grind when turning the wheel or clunk while traveling over speed bumps or something similar.

I hear a strange UFO like, bird like chirping noise coming from the rear of the car. The chirps increase and decrease in frequency but with no regularity and do not match engine rpm or vehicle speed. It will do it at idle or highway speed but gradually disappears. It comes and it goes when it wants to.

I drive a used 2012 Nissan Sentra that I purchased six months ago. Today is the first time I've ever had problems with it. I was driving down the road this afternoon and it started making a noise that's very hard to describe. It sounds like it's coming from the dash and is comparable to birds chirping or a computer-like/electronic noise. It kind of sounds like R2D2 hijacked my car! It also started making a scraping like sound from the back wheel. I thought I was dragging something under my car, but there was nothing there when I checked. When I started it again later, there was a squeak when I backed up that was either underneath or the rear right wheel side. The sounds only occur when the car is moving.

For close to 6 months I drove around with a squeak that sounded like a bird chirping coming from my dashboard windshield area. I tried listening everywhere while driving and could never pinpoint the squeak that was driving me crazy. For whatever reason, I adjusted the rubber bumper stops for the hood and the chirp went away. I had to post this just in case there were others with the annoying squeak.

I've done everything imaginable to stop my adorable Saturn Sky from overheating. I've replaced the water pump (it needed it), I've replaced the entire fan assembly (ultimately not sure it needed that), had top end cleaned, then rebuilt.
The fan is not coming on when the engine gets hot. BUT, if I pull over and pull out then push back in the fuse for the fan - VOILE! the darn fan kicks in. It may work again for a few days, or it may stop again 5 miles down the road. But I can always get it running again with my little fuse "reboot." When I go to pull the fuse, if the engine is hot, I hear a clicking like a relay trying to open and close. But, there's not a fan relay on my model.
I'm almost at the point of just installing a toggle switch to manually turn on the cooling fan.
