overheating issue....85mm built ls golden eagle sleeves, built ls head.....
gets a lil warm after driving for about 10 minutes, first had two slim fans on my fluidyne one running all the time, then switched to just stock fan which seems to be pushing more air and even put a heat shield between radiator and turbo/manifold. have stock fan to run all the time....still overheated, took the thermostat out still overheats....stays at right temp with heater on but not under boost. temp rises a little, just gets a little over half way up the temp gauge. what the hell else could it be. its a used fluidyne radiator. yes i've bleed it many times. stays cool if just idling ....WTF!!!!!! even took hood off and bleed again. stayed cooler a lil longer then slowly starts climbing ...with heater on will stay cool usually under boost too will climb a lil but go back down when i take it easy, but thats with heat on full blast.... no a/c **** in 100 degree weather with heater on high SUCKS

its a ge sleeved built ls with arp head studs,cometic headgasket

 

HOW did you bleed it?

 

i've bleed it with the car off, the car running, jacking up the back of the car,

 

42 views and no help...wtf!!!!

only things i can think of is headgasket(its not leaking anywhere, no coolant in oil and vise versa. or the radiator/or cap....(its a fluidyne w/stock fan)

 

My **** did the same as your, highway speed on a hot day the cooling heat up really bad to 210 to 225 that I have to use my heater on full blast to lower the heat down to 205 but if I step on the gas the **** rocket high again. So I take my intercooler off and used a pipe to reconnect the piping and when and test it out and my cooling drop down to 180 to 185, so I think it just the front mount intercooler that is blocking the wind to the radiator.

 

so this could be my problem

 

Bleed it again jacking the front of the car up....

Is there an advantage of bleeding it when the front is up?

 

Are you able to datalog coolant temperatures? I'm curious how high it's actually getting. Only thing I suggest is to buy a 1600+CFM fan and run it as a puller. And test for a blown/torn headgasket

 

when u bleed with the front up, the air will rise, weird how it does that huh? J/K

not able to datalog at all yet , **** isn't connecting for some reason , i had a maradyne 12in. on back and another 12in. slim fan. stock fan seems to flow better, i'm gonna try to bleed it again and take the front bumper off and see how it does...

 

Try backfilling. Also if all else fails do a hydrocarbon test on your radiator to make sure there is no hydrocarbons being induced into your radiator. If there is a small leak try a block sealant to see if it will stop the leak. At this time I am suffering the same problems. Just a few pointers Earl gave me.

and what would cause hydrocarbons being induced into the radiator...dumptube being to close to it? or leaking exhaust?and i've been having problems with my bolts to my turbo/manifold , need some stronger ones cause they keep coming loose, or would it be the headgasket leaking

Your headgasket being ruptured would allow exhaust and/or the air charge to seep from the cylinders into the water jackets under compression and/or exhaust.

 

hopefully will have it tested for hydrocarbons monday or tuesday , i hope that isn't the problem

 

any other suggestions?

 

couple of bottles of water wetter.

 

Tanner. PMed you

didn't get a pm from ya bro.....


and i put a bottle of water wetter in when i first started her up

 

i had some odd overheating problems after i swaped my engine, long story short, i forgot to put a ground cable on the starter.

How would that affect anything? There's not even a ground cable on the starter from the factory.

why the hell would it overheat if the starter wasn't grounded

 

same things happening to my friends crx, hope you have a dumptube and the wastegate isnt close to the radiator. maybe heatwrap on the downpipe good fix it.

 

yes i have a dumptube, not very long though, but i did put up a heat shield between the radiator and manifold/turbo/dumptube

A not very long dump tube? Does it just dump out under the car? Does the wastegate just dump open, or is it plumbed back into the exhaust? You do have an exhaust right?
