Hey guys can't get the car to stop overheating

[gaehrings13]

Well i've tried it all thermostat, metal radiator, changed fans, and i'm pretty sure i bleed it correctly.....

I'm starting to think its the headgasket... ugh I don't know im tired now and thinking it can only be the worst.. Well read the story please! and tell me what you think.....

Well the car kept overheating and i couldn't figure out what it is, and the damn radiator blew up.... So I replaced it with a CSF metal one. Put water in and bleed the system. I still get the same problem and my autometer gauge starts to get around 210 degrees and when i put the AC on it starts to go over it and the AC starts to go away. So i went to look for a stronger fan and a friend of mine had a stock honda fan, wich i knew are very strong. I use to use my stock honda fans on my turboed Ls integra...

All of this is without a thermostat....^^^^^

When i was putting the honda fan i noticed that on one of the larger fans that i had was getting hot on the motor.... So i decided to scrap that one and use the honda one and the smaller one.... Tried it and it started staying around 180 200 degrees.

Well today I went to hang out with a friend and it starting doing the same crap.... So he said put a thermostat back again and it should work better. Tried this and it was staying cooler for a little long but eventually it will heat up again.. Right now it sits at around 210 if i turn on the heater it will slowly get cooler.. But man as soon as the AC goes on the damn temperature starts rising quick it gets to 212 degrees to 215.....

I checked the oil it doesn't look milky the engine isn't throwing any white smoke the coolant is very very clean... also it doesn't look like any compression is getting in the water, and it isn't leaking water from anywhere at all, especially from the sides of the head lol...

Lol now i need to tell you how i got the motor i have now.The engine was free and was suppose to be perfect thats what my friends said.... I put it in and it had a blown headgasket

No problem I change the headgasket and put everything the way it was suppose to be because a retard put that engine back together... So if you guys can help me I will appreciate it, I really wanna be sure it is the headgasket before i take anything apart.

Sounds like an airflow problem to me.

[gaehrings13]

air flow?

[JeromeS13]

air flow?

Yes, as in those fans aren't pulling enough air through the radiator/condensor.

[TheOne]

you change the water pump?(check for flow in the rad) checked if its leakin?, checked if there's nothing cloggin airflow to the rad from the front.

do a compression test(or better, a leakdown test)

[gaehrings13]

Got no more money to buy anything to do those test, also the water pump is new radiator isn't leaking and the fans are pulling a lot of air. What are all you guys running lol some 50000 cfm fans or something or some 300 dollar fans cuz damn, I have tried everything I had two slim fans a large one and a small one with the clutch fan with the shroud.

I guess its time to put the 240 to sleep and buy another car...

[KATwo40]

I tried using slim flans and have the same problem. Seems that everyone goes with Altima fans and things work well.

[Edub1]

Have you tried the stock fan & shroud?

[hek1620]

i have altima fans on my kae-t, and she overheats when enduring long periods of high rpm's. she goes up a lot quicker with the a/c on. but i could be stuck in traffic with the a/c on in 100* weather and she stays normal.

[gaehrings13]

Are you turbo, weren't you that guy that wanted to change the emanage for the safc where in hialeah are you, sounds like you are almost having the same problem. Well atleast you can drive your car normally lol. The problem is i'm out of money for the car right now... I really need a beater becuase is if i did I really wouldn't caire.

Then I could work on the car without relying on it entirely... Thanks for all the help guys...

I was wondering what do you think about timing... I still haven't put a timing light on the car.. I remember I was working on a crx that i put a motor in it and the timing was advance a little and it would heat up real fast, I retarded it a little and it was staying perfectly cool...

What do you guys think about that.

[gaehrings13]

Okay guys I got one more question, do you think its the headgasket if there is no water in the oil, no oil in the water, no large clouds of white smoke coming and no leaking water from around the head.... would it still be the headgasket.... I don't mind changing lol, it is my fault if it got messed up anyway cuz the vac signal for the wastegate was leaking and I couldn't hold steady boost... What do you think is the max I could tighten the factory bolts without breaking them, I torqued them to 70 ft lbs..... Im prepared to change the gasket so let me know guys and I will do what you say lol.

Let me know dudes!!!!!!!!

[TheOne]

compression test:), its like $40 for the tool @ autozone.

[gaehrings13]

Lol $40 for the tool, car still broken.... 40 dollars for gasket and it might start working lol..... Do you think that the test will be significant enough to show a huge drop on the compression, I'm almost positive its the headgasket... I wish I had a little more dough to buy some studs and another gasket, but this time im going to see if I can get my hands on a felpro gasket instead of a Rock auto....

The rock auto looked of pretty good quality... Well does anyone know how much the stock head bolts can take?

[hek1620]

yes, thats me. i'm still trying to get rid of the emanage. i need a koyo, i think that will stop the overheating.

[DammitBobby]

Pull your thermostat out, run the car without it. I am willing to bet it won`t. I can`t tell you how many dam cheap thermostats I have bought that would overheat intermitantly. I finally broke down and bought a Nismo and have had no more overheating problems. If you are out of money pulling the thermostat is free. If this works and you are broke leave it out until winter time.

[JeromeS13]

If you read the first part of his thread, he was having problems with the thermostat out.

[DammitBobby]

Crap missed that one. I briefly read through it.

There is some kit they sell at NAPA IIRC that will test the radiator water to see if there is any exhaust gas in the radiator water. That will explain the high temperature you are experiencing. Sometimes the head gasket will leak between a water jacket and the cylinder causing what you are experiencing.

[gaehrings13]

Thats what I was thinking dammit bobby, If the engine wouldn't run so good I would just change it but it pulls so hard..... I don't smell any exhaust in the radiator, Ive seen it happen on a v8 newer model montecarlo... I will go today to my friends shop and use some of his **** to check the car..... Do you think retorquing the head would help, remember I just put this head gasket in but the head bolts that I used were the old ones..

[Florida240sx]

If you get into your engine again you need to have arp headbolts.... My stock headbolts caused a world of mess with me...I about cried when I saw oil coming out the side of my block on a 0mile engine..... Check you fluid again just keep adding water to it till it overflows and go for a drive and then check it once it cools down to see if it went down any...I have a koyo and flexalite dual 12" fans and it overheated on me if I was cruising or at idle. If I accelerated it would cool itself....I was a little bit low on fluid...

Hot day on Interstate going 85-90: 225ishNight time Interstate : 200-205ishAround town Daytime : 195ishNight time around town :175ish

[gaehrings13]

damn 225ish did your stock temp gauge move any during this time... Was there water bubbling in your reservoir... I wish I had the bucks right now to buy the arp studs, I had them once but I sold the car with them and the engine was blown, im so dumb I didn't take any of the **** off....

[Florida240sx]

gauge stayed in the middle, I was getting my reading off my mdm techtom which intercepts the signal from the ecu.... Drove 1000miles over the weekend from central FL to ATL not a single problem engine wise..... just other htings like brakes and missing bolts....

[DammitBobby]

Yea, your not suppose to reuse your head bolts. I would do the test for exhaust in the radiator first and make your decision based on the test results. If I had to pull the cams to retighten the head bolts I would wait until I had 90 bucks to buy ARP. That way you won`t be second guessing yourself and if you had to replace the gasket you would all ready have the proper hardware. Let us know what you find on your test.
