hey people!!
this is the story! i have a built h22, 9:1comp, full race setup, SC61, rc550, 3 inch open downpipe, 0.5BAR BOOST

in a JDM 1993 prelude, BUT im also runin a Civic fluidyne RAD (space reasons) 2600cfm 14"fan

anyway, ever since i ran the motor in its been gettin real hot, even at idle! i have changed the thermostat, bleed the system twice, bigger cfm fan on, water pump, water wetter, richined up the AFR. put a carbon bonnet on! cut holes in the front bumper to flo air to the rad!

AND ITS STILL gettin hot!
im running AEM EMS TOO, BUT i live in ENGLAND, NO AEM TUNERS HERE!
THANKS GUYS

 

i had the same problem, turned out that the first time it was the HG, the 2nd time it was the damn rad cap

could be your problem right there......i noticed that 8 out of 10 guys running cometic headgaskets have problems with them.......hope your not one of those 8

 

Cometic headgaskets are usually used as a quick fix on a messed up motor.

totally false...... Many, myself included run cometic gaskets... they're a great gasket, and great of if wanna knock ure CR down a few more ticks

 

are you running teh civic or lude radiator cap? there might be a pressure differance between the 2. also you can do the washer trick and put washers between the hood hinges, and the hood, and allow heat to excape through the back.

also wrap the turbo manifold, and downpipe with heat wrap it will cool the engine bay down alot

 

i am running water wetter! im usung a fluidyne rad and fluidyne rad cap too. im going to do a compression test soon! ill try and get pics of my setup too.

i have just ordered a oil cooler

remember this is in a prelude with a civic rad!

the head gets stupid hot too. im gettin really fed up now, i have a show to go to in august and i still me to fine tune the EMS too

 

that was my best freind answering what he says is right!

know what u mean

 

Well if you'd been on Honda Revolutions, you'd have seen that Mase is coming over to the UK at the end of this month to tune some cars!!! But its pretty much full up now unless we get enough to book the dyno for a second day. PM me if you're interested but be quick about it!

What show are you talking about, Ultimate Street Car at Pod? I'll keep an eye out for your car then, hoping to run my little turbo ITR there too

 

You might also want to make sure that your rad. fan is pulling air from the front of the car back instead of pushing toward the radiator.

 

exactly i had heating issues for a week......i got a h22 in a ferio, i changed my thermostat, didnt fix it, changed my fan didnt fix it, changed all the hoses with the swap didnt do anything, so i bought a new dual core radiator and that fixed my problems, i thought i had a blown headgasket but i wasnt to sure, but i said o what the hell 85 bucks let me go try it out did and im all good ever sice couldnt be happier

MASE HAS ALREADY been here a couple of mouths ago! is he due to come again?
ill be interested if he is!!!!!! i never had the money then!!
please contact me with details!!!

 

A shop can do a pressure test, it involves two color dyes:

IF the dyes mix yell/blue to form green, coolant is leaking past your hg and causing you to overheat. Sometimes you can watch your overflow res and if it starts bubbling a little every now and then that usually means pressure is coming out of the motor (blown HG)

Usually overheating is caused bya bad thermostat or bubbles in the line.

YOU WOULD BE VERY SUPRISED AT HOW LONG IT TAKES TO GET ALL THE BUBBLES OUT OF THE SYSTEM. Bleed it about twice as long as you think it needs to. I found this out the hard way this weekend.

Like half an hour with the heater on.
