Car Overheated / Overheating / Overheats [MERGED]

[NTRCOOL]

OVERHEATING? The issues and their solutions have remained the same- either you don't have enough cool air reaching the rad, there's a cooling system obstruction which is preventing coolant from circulating, or your head gasket has failed and is allowing coolant to be consumed or pushed away from the engine.

Discuss all possible overheating problems and solutions here.


OK,
I just left my house to go over to my GF's,and happen to look down and see my needle right before the red mark. This just happened out of nowhere. I stop the car as quickly as i can, and pour in some coolant(Coolant a little low). Still same thing. Welp im in the middle of the road, and HAD to get it home. Im only 5 min from my house. I decided to try and make it(I really had no other choice). Welp I drive no faster than 20mph, and the temp needle is BARELY into the red the whole way.And occasionaly to the left of it. Am I ok?? Do ya think any damage was done?? And im thinking either thermostat, or water pump. For each of those, whats a round about $$ figure to get replaced?? Any info you have would be GREATLY appreciated!

Well boys once again I want to thank you all. I checked my thermosensor as instructed earlier and it is bad. So once again this forum and member have saved me again, if it wasn't for you guys and me trying to work on the car I would have shelled out some serious $$$$ to the point I couldn't even afford this car. To all the newbies. Learn to work on you car the gratification is worth it. Again thank you so much for all the help...I bow down to all that helped.

the fans do come on.

he car ran great the past 2 days to work and back, and a few pulls.

but tonight, another lil tear was found, the upper radiator hose. heard it hissing like crazy.

so, i got 2 new hoses , a new radiator tonight i shall install in the morning, so lets see what happens.

so far that would be :

turbo coolant hose
lower heater hose
coolant bottle hose
waterneck to intake hose
upper radiator hose
all of them have cracked/lil tears which caused coolant to leak out.

this car came from oregon , where it never reached 110 like it does out here....

maybe thats a reason why ?

lets hope the radiator solves the prob.

if there is a sudden temperature change like that then i could buy all of your rad hoses leaking at the same time. changing the rad is never a bad thing to do.....but check one more thing for me, look underneath your car on the timing belt side and look up and around that area between the belts and the engine. see if you can locate your water pump. do you see any signs of moisture? or do you see any "white stuff" dried on to the metal, or powdery to the touch?

if your fans were coming on before, and your car still overheated, then you have a problem with a blockage, the thermostat, or the waterpump. since you've eliminated a blockage and the thermostat, then i would closely scrutenize the functioning of your water pump.

if there is any "white stuff" or ANY signs of moisture in and around the bottom half of the timing belt area or on the water pump, REPLACE THE PUMP immediately!!

if you see no evidence of a faulty pump, it doesn't mean it actually isn't. the seal might still be intact, but the blade might be shot and there won't be any water moving. after you are done replacing all of the hoses, and the rad, and the thermostat, and if the fans do still come on, and it STILL overheats......then just replace the pump. let us know how it goes man.. and good luck.....

I purchased my Talon for cheap a couple weeks ago because it was leaking oil real bad. Prev owner overheated it(bad thermostat). The leak is from the head gasket, right behind the exhaust man. between 3 an 4 cyl. It still has great compression(about 190 in all 4), no coolant in oil, or oil in coolant. sounds like this issue is pretty common.

 

[EvilAWD]

you know i have the exact same problem only thing is i have a fluidyne radiator some spal fans new radiator cap and thermostat from dealership and i still overheat. although only problem i do have is cylinder number one is at 120 while the rest are at 150. more than likely its going to be a BHG. does anyone else have any other ideas of what it might be?

 

[Cheks_Talon_TSi]

What about your oil pressure?? maybe the oil pump pass away or is blocked somewhere... or maybe your water pump isn't pumping what it should be...

I don't have any more clue about your problem... take a look on the water pump and oil pump. Good Luck!!!

[EvilAWD]

you know that might be a possiblility. as i was installing the new turbo on my car the wire for the oil pressure on my stock gauge disconnected. so i dont have a guage that displays the oil pressure. i should get that checked out. thanks

 

[sYnOnYx]

FIXED , atleast i hope.

i hard wired the fans to come on when i turn the car on.

and i must say it keeps the car alot cooler , mine was turning off after 30secs before.

been driving it like 3 days now , and it runs awesome...

Ok!, hope it works for you...

Good luck and let us know!

i took my car to the shop last week it was the head gasket and the head was warped and cracked and the valve cover was also cracked I'm going to get my car back tomorrow

 

[BenHenthorn]

Hey guys I'm back with an update.

I really don't think it's my water pump anymore. Now I see the water flowing but I think I see another problem. Even after I let it idle for about 20 minutes I see little air bubbles coming out of the radiator cap. Could that mean I have a head gasket leak? I'm more confused about this than before, the A/C doesn't even work after a few minutes of operation. What do you guys think it could be now?

 

[silvercoupe97]

Hey Ben, just an idea and question...before you installed all that stuff, did you put your water hose on the thermostat housing and let it flow to the bottom of the motor? The reason I ask is because you might have a blockage from debris. It doesn't have to be huge, just big enough to cause problems. Except for the thermostat, everything should be able to free flow through the block and radiator. Try the water hose trick if you haven't already.

Also, if you had a head gasket problem, you should see oil in your radiator fluid or radiator fluid in your oil.

[QUOTE by silvercoupe97] Hey Ben, just an idea and question...before you installed all that stuff, did you put your water hose on the thermostat housing and let it flow to the bottom of the motor?

What exactly do you mean by that? I did notice a little bit of black stuff in the radiator fluid but it looks like just a little bit of debris. I didn't actually see the water flow today, and it heated up really fast. But I saw it flow yesterday, and it took a long while before it heated up, so you may be on to something, I'd just like you to clarify on exactly what you mean. Thanks.

Lol, sorry about that Ben. After reading that quote it did sound odd, . What I meant was...put the water hose up to the thermostat housing and then have someone turn it on. Wait, back up. First remove the upper radiator hose that connects to the thermostat housing and radiator and the thermostat while the motor is cool/cold of course. Then hold your water hose on the housing or the radiator opening. You should get a free flow of water and left over coolant in either the housing or radiator (opposite of where the hose is). The flow from the opposite end isn't going to be like the flow from the hose because of the water's route through nooks and crannies but you should still get a decent amount of flow. Doing this will also loosen and remove loose pieces of debris in the cooling route. It might not solve your problem (hopefully it does though) but at least you will remove the possibility of debris clogging a route in the motor or anywhere in the coolant fluid flow...and if it does, you've just saved money by spending money on more coolant instead of an engine rebuild .

I really hope this works for you Ben..I hate to see a good car down.

 

[silvercoupe97]

Here's a little trick to the above too...
Put your water hose on the radiator opening or the thermostat housing and cover it up with your hand (cup it). This will direct more pressure through the radiator and motor instead of just running down the motor or radiator, don't turn the water hose pressure too high either..there's no need to do that

I hope that was easily understandable

 

[BenHenthorn]

Thank you for your input silvercoupe97, I'll make sure to try those things after my car cools down again. I just drove it around without the thermostat, which it actually did quite well, but it overheated when I tried using the A/C. It was fine up to that point and after I used the A/C it started to consistently heat up like it did before. I probably need to clean out the system, but for some reason I just think it's something else.

I see what you did there. The reason it stayed cool for so long until the A/C was turned on is because of the extra load and with a fully open flow...all that's going on there is the coolant "grabs" the heat from the motor and keeps it. That fast flow doesn't have enought time to get a cool charge from the radiator because it's just flowing past it in a continuous cycle. When you get a chance, push on the thermostat valve to be sure that it does move as it should.

Have you turned on the heater (turn off the A/C too) when it gets hot? If so, did you notice the temp level out and stop rising?...did it lower the motor temp?

Maybe change out your coolant temp sensor, another thought...could be cheap coolant with bad heat transfer?
That's all I can think of at the moment. Remember that the oil affects engine temp too.

 

[GSTurbo05]

Im not sure if its my car or my thermostat buuuttt my car temp is showing like its overheating and it all started this morning. The funny thing is when i made a left hand turn onto the freeway the temp went down to normal temp then came back up.I sont see no smoke but my cars fans run forever and i dont hear my water boiling like crazy neither.Could it be just a stuck thermostat?

 

[Goodguy162000]

Sure could... it's an $7-$11 dollar piece. Throw on a new one and find out. Easy enough.

 

[GSTurbo05]

THX but i found out the problem. EASY as boilover in my coolant. So i added coolant, it was so empty it almost took a gallon of coolant. Very hot out here in AZ im use to California

 

[93_GSX_AWD]

i am in need of some help. i have flushed my system at has a new raditor and new electric fan new thermostat. well ok heres there problem while starting up and driving its fine but after driving 50-60mph for awhile then going down to slow speeds like 20-30mph it starts to overheat it gets above the half point and close to the hot line. i have also hooked up a water temp guage too so i know it is for sure it is overheating it gets up to 230 degrees. while any help will do thanx for your in put

travis

 

[oldman]

new electric fan

Would that be stock or aftermarket fans? Are you sure you hooked them correctly and they're comming on when they're suppose to?

 

[BenHenthorn]

Ok, I just can't figure it out. I took my car to my DSM guy and he can't figure it out either. He tried to tell me that my intercooler was the problem and to get a smaller one or a sidemount one. But lots of people run big FMICs and don't have this problem. I'm all out of options unless I can squeeze out a few more ideas.

 

[93_GSX_AWD]

itsa new i got one 12in aftermarket fan on there with a adjustable thermostat. i have it set at 185 for the fan to turn on. i was thinking of putting another fan in there.

 

[ITSME4G63]

is your fan blowing towards the radiator or away from it?
