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!

its boiling into the reservoir, what do you mean by pushing coolant?

Blown head gasket, the pressure in the combustion chamber is leaking into the coolant ports most likely,pushing the coolant out of the system

Even though you did a leak down test you could still have a leaking head gasket, did you do the leak down test with Radiator cap off?Same with a compretion test you could come back with good numbers even though it's got a small leak in the H/g

Also you said you over heated then it keeped over heatin' after that You could have slightly warded the head from the first time then fixed what caused it.... but it would'nt matter at that point

Head gasket.

 

[92laserboy]

well the raditor isnt clogged because we have flushed it 4 times but for the heater coils we havent checked them to see if it was clogged and the water pump is good and we will check the thermostat

 

[v8s_are_slow]

When is it overheating? At idle or slow speeds? Does it overheat at highway speeds?

Just because you flush the radiator doesn't mean it's not clogged. It can get clogged and need to be taken to a radiator repair place to get it all cleaned out. Just because you spray a waterhose on your car doesn't mean it's gonna get all sparkling clean. Needs soap and scrubbing. Get my point?

Not to say it wouldn't be something like a headgasket or something but giving some extra ideas. And what about the fans?

 

[jdunbar10]

he has the fans hard wired in to where they always run

i did that with slim fans

kinda sounds like the head gasket but yeha till you do a leak down test i think that would be best place to start

 

[donswan]

I would really check the heater core or the head gasket. A leak down test is easy to do if you follow the link up above.

I had an overheating problem with my car and it was spewing out of the overflow bottle...I was told head gasket so I replaced the head with an upgrade and the headgasket with a cometic..used studs as well...anyways i got it all back together after replacing all of that plus a couple of thermostats and flushing the rad a bunch of times...took the car out after new head and gasket and it still overheated on me!!! i spent like 1600 in parts and it turned out to be the rad was clogged!!!so i could have bought a new rad for like 150 and hit the road but i learned the hard way...Get a temp gun and make sure that the rad is the same temp all over....when i would let the car get to operating temp the top rad hose was burning hot but the bottom one was cool...so....good luck

If you have bubbles, that means there is air getting in your system somewhere. Are the bubble small champagne type bubbles that look like foam as they build up?

Yes, but are the fans rotating the proper direction??? Are they pulling air in? Or pushing it forward?

 

[jdunbar10]

ah very good question,

but since he is running stock fans i would assume they would be pushing

 

[gsx7707]

if bubbling when you take cap off you definetly have a blown headgasket

 

[Captain D]

A bad head gasket can cause the engine to overheat. Bubbles in the overflow or in the radiator with the cap off is caused by the piston pushing gases into the coolant. Black powder in the coolant or black stains inside the overflow is caused by exhaust gases mixing with the coolant. If the head gasket is bad you need to stop running the engine and replace the gasket because a severe overheating condition can cause the head to warp and/or block to crack.

 

[92laserboy]

yeah i have stoped driving th car because i dont want it to get any worse but i will check the radiator to see if it is clogged

 

[v8s_are_slow]

You can still get water thru a clogged radiator. But it won't flow well like it should. So just seeing if water goes in and comes out doesn't always do the trick. May need to take it to a radiator shop....or just see if you can borrow someone's to see if it helps with the issue. Have you checked for the head gasket being the issue? You're not giving much info in regards to your problem. We don't know when it's overheating, what all you have checked, etc. Oh well.....

 

[garrek11]

your best bet it too make sure you don't have a head gasket leak or heater core and if you don't i suggest you get a new radiator.

 

[Ill-EagleTSi]

well my engin is still over heating we have put the following on a raditator cap,thermostat,we ran straight water through it befour which was not good but now we are running coolant through it 50/50 and the reservoir bottle and the tube that goes in that bottle has steam coming out of it making the coolant bubble out of the bottle we have the fans straight wired to run all the time and it is still running hot it is getting to be a pain and would the throttle body have to anything with it overheating but i need some help badly

It is your Head gasket. I just went through this exact same thing

 

[91turbodsm]

Hey guys I desperately need your help. My car has been overheating for the longest time now. I made a thread over on dsmtalk and I will post the link here. The link over there has alot of updates through this whole process, so I figure it would help you guys help me diagnose the problem. Here is the link:

Wiring Punishment racing fans in a 1g - DSM Forums: Mitsubishi Eclipse, Plymouth Laser, and Eagle Talon Forum: DSMtalk.com

Here is an update to follow that thread.

UPDATE: So I had the headgasket done after the mechanic telling me the leakdown test pointed out the HG to be the culprit. So I take it out and run it with the ac on full blast as cold as it will go. I run it up one of our mountains here, and it goes all the way over the the second the last line before over heating on the right. So I come down the mountain pretty much just coasting. When I get to the bottom the needle is standing straight up and down. I then proceed to go like 2 or 3 miles to my house. By the time I get to my house my car is almost in the red again. Its right at the second to last line on the right. So I park it, pop the hood, and hear a loud whisteling/hiss from somewhere. I also notice the upper radiator hose is swollen and flexed upwards, I think due to it bieng about to burst. As of now the car is just sitting there. And yes both fans work, the car is running 10 30w fully synthetic oil. Really the only thing left in the cooling system is the water pump, but the car is not dropping any fluid anywhere.

Ideas on what could be the problem??

On a 1g there is a long transfer tube that the upper radiator hose connects to and the other end connects to the waterpump. It building up that much pressure is a sure sign of a restriction somewhere in the cooling system. Normally i would say radiator but after reading your posting on DSM Talk I am leaning towards the transfer pipe clogged or restricted the connector between the water pump and the transfer pipe collapsed or restricted or the water pump gasket slid or moved out of position during installation.

With it shooting coolant out with that much pressure the path from the thrmostat housing to the water pump is somehow restricted or the gasket for the water pump is blocking the coolant flow.

Thats my two cents worth.

 

[91turbodsm]

So your talking about the metal water pipe that people usually dent when they have a turbo with a big compressor housing? If that is the one your talking about then it connects to the lower radiator hose. You think that might be clogged? Or you think the water pump might be mis alligned?

Also if that is the pipe your talking about how would you test if its clogged? Also, what in the hell would clog that pipe? I dont know if anything of anything that big that would go into the cooling system and clog it up.

If the water pump gasket was missaligned wouldnt it leak water/AF? I am not dropping any fluid at all.

even though the HG was just replaced, i just wanted to point out that i have had that happen on my car with a bad HG. leaks from cyl 3 to 4. i found out in leakdown test. it shot straight out of the thermostat housing just like that even with a thermostat in place. but it only did it when the thermostat was open. if i were you i would have the system flushed and checked, and take it to a different mechanic because it honestly still sounds like a HG. maybe under high rpm the water pump could do it if the thermostat wasnt in but otherwise i dont see where this type of pressure would come from other than the HG. is this guy using the old head bolts to try to torque down your head? if they're stretched it will most likely cause the head to not seal right. just an idea though. and my .02 cents

 

[91turbodsm]

Well tonight when the car cooled down, I took the cap off and revved the motor. When I did this, nothing happened. This is also with the thermostat in.

On top of the overheating issue, my problem is, is that i have CEL and I dont know why. Also, the car sounds like it has a timing problem. The mechanic retarded the timing on my CAS "so I wouldnt overheat." Now the car just sounds wierd. I mean it still boosts hard but it idles like crap. But I am going to take it to the guy who tuned it originally so that hopefully he can fix all these problems. I am so sick of the damn car I just want to sell it. It is driving me nuts. I have spent over 1500$ in the past few months trying to figure out the overheating issue, and still nothing.

I will let you guys know how it turns out. If you have any more advise shoot it my way.

Oh and also the guy is reusing my ARP's that I had in their. They are definetly not stock, but hopefully they didnt stretch.

I spent 3000 on mine before i even got to drive it.

 

[91turbodsm]

Thanks for the link! The one about the AC makes sense. Because when I went up the mountain here, I had my ac on all the way, which in turn caused it to overheat. Then I turned it off and temp dropped back down. Then I also drove it around all day yesterday w/ out ac, and it didnt give me any problems.
