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!

Any updates if the timing was set properly?

Dude, check your radiator cap. That is one component that is often overlooked. If it's not holding pressure in your coolant system, the boiling point goes down and causes overheating. On one of these recent overheating issue threads I posted some links for coolant leak down testing. Check out the 2 links I provided in that thread.

Its called a leakdown test....Check it out

You recently showed me once again how somebody that doesn't know how to do regular maintenance on his car will cry about how "unreliable" a dsm is. Maintenance is key to any performance oriented vehicle. I haven't had any reliability issues with my gst. Want to take a wild guess as to why that is?

And drain that water out of ## cooling system ASAP. Water has a lower boiling point than antifreeze, well when mixed with water anyways. I believe just pure antifreeze may have a lower boiling point, if my mind serves me right.

No one is crying, I'm just ranting. I been working on restoring this DSM for a few months now and I had it running for about a month now. I do my own maintenance, I also have people who help me do this. If you have nothing positive or helpful to say, keep off the forums and chew the foreskin off your father's cak.

I did figure it out this morning. One of the thinner hoses are flimsy and soft, it kept breaking open after awhile so it isn't anything major. Just need a new hose to rectify this problem. Thanks for reading.

 

[LambdaJoker]

Well you did come about saying how dsms are unreliable which isn't true. And me telling you to properly maintain your vehicle isnt helpful? I'm just lookin out for a fellow dsmer since were a dying breed. And I do believe the second part of my post contained some useful information.
We can get into a piss contest, but for what? For you getting offended at my statement about maintaining your vehicle?

 

[97gst_spyder]

I run tap water in mine...180-190 all day in 95+ degree heat. Not saying that you should run straight water but its been working like that for a year now...

 

[50trimgst]

Idk know how you can say a Dsm is reliable.

Reliability isnt measured in a motors ability to work under perfect conditions. Relable means how many things can go wrong before this thing stops working. A car that can run with a broken knock sensor is more reliable then one that cannot. An engine that breaks over every little problem is less reliable.

Antifreeze has a higher boiling point than water due to the intermolecular forces of attraction that are present. It also has a lower freezing point due to the same effect. Antifreeze is ethylene glycol which has a higher viscosity than water, thus a higher boiling point. If you mix the two together in 50/50 ratio the boiling point of water will be slightly higher than 212 degrees Farenheit. It all depends on how much antifreeze to water ratio you have.

Damn thats a great explanation! Thanks!

I concur.

My antifreeze got hot enough to burn through a rubber hose while just idling. I'm pretty sure that the hose is just worn out at this point.

this made my day.... oh man did i need this...!!!!

I got this from the June 2000 Underhood Service magazine in the new coolant chemistry article by Larry Carley.
Straight eg (ethylene glycol) antifreeze should never be used in an engine because it may allow the engine to overheat. Likewise, straight water should never be used because it provides no freezing, boiling, or corrosion protection.

hahahahaha i agreee. made my day as well.

 

[dboyle23]

You have to have a mix of water AND coolant to not cause any problems.
Water transfers heat MUCH better than coolant, but it has a low boiling point and a high freezing point. So a mix of both gives you the best of both worlds, a liquid with good heat transfer and good resistance to freezing and boiling.

 

[Mschooley]

Okay, so here's the deal I had a motor built for my car and put in so I got brand new rods and pistons and had my crank remaned and had a waterpump with low miles put in so the water pump aint bad and I don't have a blown head gasket or bad head.

I replaced the thermastat, radiator cap and my fan is working correctly. My guage doesn't read overheating but my coolant bubbles n my overflow bottle. Also have an issuie to wear it feels like it has no power if I full throttle it kinda like a boost leak and it studders up till about 3k rpms. Any ideas?

 

[Absit]

Bubbles in your overflow is probably because you didn't fill your cooling system properly.
And do you have a boost leak?

 

[deweese46]

that is what it could be or the radiator could be bad.What mods do you have done to the car so we can try and find a reson why it might be acting crazy when you mash the gas

 

[240man91]

I would say air for the overheating to, or mayb a temp sencer if the gauge dose not read hot but it is. An dose it idle hi cause i have seen one where the temp sencer was bad an the gauge wouldnt read right so it caused the car to stay in cold start mode an made it run bad an idle hi an over heat. in th i.c piping stock? An is the bov stock, if so how old is it

 

[Lambiablo]

Under what conditions does this occur? After driving the car kind of hard or most of the time. Also, if the power issue is only until 3k or so, and goes away thereafter, then it is unlikely that it is a boost leak.

 

[Mschooley]

I was thinking there is a boost leak is why its accelrating like that I'm not sure exactly. I have a hks bov and it is recirculated has full hard ic piping with a front mount. Thanks for the replies ill try and burb my cooling system tomorrow

 

[Lambiablo]

I once had a strange overheating issue that only really came up when it was really warm outside. However my gauge would register a little hotter than usual. Then occasionally when I would get on the throttle it would try to get really hot and the coolant would boil for a couple minutes. I believe it was a combination of the front mount blocking airflow to the radiator as well as a larger turbo and tubular manifold. I even bled the coolant system and pressure tested and found no issues there.

 

[Mschooley]

Basicly how I can think to describe it, kinda feels like im trying to brake boost. Like it spools the boost all the way up to 10 PSI but its not going any faster, but if I half throttle it, I can pick up a little bit but no where to where it should be. It runs all bogged down under 3k doesnt idle ####ed up or anything though. I honestly cant think of what it would be if its not a Boost leak cus everything is brand new except for the Transmition my motor has like 140 miles on it right now. When I got off work I put actual coolant in it instead of water I drove it around for awhile and parked it no bubbling this time. One reason I think maybe it was boiling is becuase of the fact that my overflow container is a glass beer bottle and it had water in it instead of coolant. Water boils at like 100 c coolant boils at like 190 or something like that.

Id also like to add the car did sit for like 5 months or so with old gas in it. Could that be an issue maybe?

 

[deweese46]

It could be try flushing your fuel system and injectors and try agine

Check to make sure that your timing marks are correct, if it's a tooth off it could cause all sorts of problems
