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!

Make sure you have the right spark plugs also. My gst had the same problem when I first bought it, and when I took it home to do the maintenance on it, I found the wrong spark plugs in it. Replaced them with ngk bpr6es's, and it boosts normally now.

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

You know I took me five minutes longer than needed to read your damn post. Spelling, puncuation and grammar are mandatory.

Plugs is a good point, anything other than ngk's and the car may not perform properly. I also once solved a strange boost issue simply by replacing the pcv valve, I assume is was sticking and it was screwing with the vacuum. Those are two cheap and simple options you could give a shot at.

Have brand new NGK spark plugs and wires on it they have a about 140 miles on them along with the engine. My manifold also glows orange at night even after short drives, Im guessing its cus im running rich. The other day my stock downpipe broke off after the flex part. When it was off seemed like the car pulled ALOT harder think maybe my exhuast is clogged up somewhere? any ideas how to fix that if so? My PVC is screwed in all the way and not sticking.

I was getting like 10 mpg as well i went through a whole tank of gas already with only 140 miles...
Thanks for all your guys help and suggestions so far I LOVE THIS SITE! haha usually can figure out all my issues

 

[deweese46]

Yes also true could be your plugs ngk are the best thing to run in it and it also could be your timing marks,his right one tooth off and it can cause alot of problems.Or could have been bad gas like you said from where it set for a while.

 

[DSM1G90]

Im guessing its cus im running rich

.. I call it running lean since you got more oxygen than fuel.... and lean situations can make things super hot.

 

[LambdaJoker]

Just because the spark plugs are new doesn't mean anything. They may be the wrong heat range. That's why I said to make sure they're the right ones. Which plugs did you put in? Not brand, but rather which heat range?

 

[Lambiablo]

Yes a glowing manifold on short easy drives generally means lean.

 

[Mschooley]

It stoped overheating must of been air in the system or something. Last night i reset my ecu started the car and it pulled like normal for about 2 pulls then it went back to running like shit. hmmm im stumped and the timeing is right on

 

[DSM1G90]

..best check your fuel mixture settings then. what do the plugs look like after a run like that .. all blistered white per chance? Try running a much colder plug then .. like an BPR7ES, or BPR8ES plug if the plug is all white and blistered from running too hot.

That's a super lean burn, if you ask me. Keep doing that and you gonna melt and bust something up real bad.

I have a 99 gsx. It had a Big t28 and greddy front mount long pipe kit and I removed those and installed a Big 16g and PR Frontmount and short route kit. Ever since it has been running hotter and Idleing up. I made a panel to go from the front bumper to rad support to "force the air thru the rad", Replaced t-stat, rad cap, and Pr full aluminium Rad. The cooling fans both come on. I was sitting at a red light and the temp gauge went up to 3/4 and I turned on the heater and started driving and the gauge came back down. I dont know what else to try?? I got a date on friday and need to get this fixed!!

 

[Absit]

Did you duct air from the FMIC to the rad or just from the bumper to the FMIC? Did you duct all around it or only one side?
How old's your coolant?

 

[bjmauck]

I put the duct on the bottem to the front bumper to the rad support. I used new coolant. But it overheated sitting still at the red light like cooling fans not pulling enough air. Its 97 degerrs in Ga too!

Try getting a cooler thermostat 160 degree temp instead of the 190 stocker. A higher pressure radiator cap will raise the temperature at which the coolant boils which would be good for your case since your running hotter, be careful though cause the pressure in the system will increase putting more stress on the hoses and such, if you have a spongy hose it might pop . Big Front mount=higher coolant temps. My car did the same thing now that i think about it. If it was heating up at a red light i would just hit the gas a little to raise rpm's and the coolant temp went down. Might have been the water pump or a clogged radiator, i sold it before i could figure it out though. If it does lower the temp by raising the rpm's a little, just set your idle a little higher for the time being untill you figure out the main problem. good luck !

These threads might have something that helps,
Do you have the turbo heat shield on? any wiring damage from underhood heat?

I have the lower t-stat and higher rad cap already! It idles up by its self to about 3k rpm

I have tublar manifold and 02 housing. the lower shield is on but not the upper. that was already on before the problem started tho.

 

[4G63KING]

Hmmmmmmmmmm

Re: Idle - Your throttle cable is probably too tight if it only happens when it's hot.

Will the slim fans Cool better than the stock? Ive seen lots of issued with them burning out so thats why I didnt get them.

I got 2 12 inch slim fan that are 800 cfm a piece. Im going to wire them where they both come on like regular and have a switch. Hope this does the trick

Cooling fans on! Still over heating!! Could it be a bad turbo somehow causing it to overheat?? I'm lost! I need some help on this. I can turn on the heater and it gets better.

Hi everyone, I'm new here , actually I'm new to the whole dsm thing. This tuesday I got myself a '97 talon tsi, FWD, motor and tranny were recently freshened up with new oem stuff, it also has t3/t4 turbonetics turbo with manifold, turbonetics wastegate, blow off valve, front mount intercooler (not sure what brand), Apexi full exhaust, Apexi boost controller and fuel management, walboro 255 pump, don't remember what size injectors, B&M short throw shifter, yonka (I think) coil overs, and Excalibur remote start. Car was dynoed at 285fwhp on 19psi 93 octane before and now sits at 10psi only (have no clue how to adjust boost controller and fuel management). Car is a blast to drive and currently serves me as a daily beater so I can keep miles of my mustang.
Yesterday I started having first issues with it. As I found out recently it has no coolant overflow tank and coolant line that supposed to go to it is simply dumped behind tranny, so yesterday I noticed that car runs hot, and there was steam coming out from that dumped coolant line. In fact I don't even know how to check coolant level, so I just topped coolant all the way to the fill neck ( took like 4!!! Qts) now I added cheap autozone overflow tank and ran that dumped coolant line to the bottom of it. I noticed that car still overused slightly when I sit in traffic, fan kicks in, runs for like 20-30 sec then shuts off, then turns on, then off again, and just keeps that cycle. WTF is that? And driving that low on coolant could I #### something up already? I roughly drove with low coolant for about 25-35 miles before it started overheating I think. I talked to my buddy and he said that overheating can be caused by bad coolant temp sensor, would you think?
Another problem I had is that on the same night when my car overheated for the first time, I could not start my car for shit, after cranking it for like 5 min on and off it did a eventually started and ran fine. Then I turned it off 20 min later same problem, then I got home turned it off, added coolant and overflow tank, then tried to crank it and same thing again! Today it cranks almost right the way, and once in motion runs like a champ. What could all those problem be, and could they all be related because of low coolant?

Have you checked for leaks. Obviously you are loosing coolant.
I would have not driven the car at all if it started overheating.
Is it mixing oil with coolant.?
How bad did it overheated.
I will rather daily drive the mustang than the Tsi. Imo.

 

[Kod]

Have you checked your relays? For the fan issue.
As the above user posted, is oil mixing with coolant? If that's the case then head gasket is shot.
Have you checked to see where its leaking? If it's metal you could try K Seal in the coolant, works great, personally never had issues with it and have used it on many vehicles with head gaskets leaking and what not.

I know on the ICS I think its what it is, there is a port on the throttle body and is known for clogging up which maybe your line is leaking there.

Yeah the leak was from dumped coolant line that supposed to go to overflow tank, that's fixed now, actually so far so good, it's starting right a way and stays cool. I don't think that relay went bad, other wise fan would not turn on at all. I will just pick up slim fan and place it where a/c fan used to be. Oh and my mustang is '08 with Eleanor body kit, stock motor but it's just to nice to drive it daily on ####ed up MN roads.
