Overheating again!
 

Well, got the turbo on, radiator was cracked so replaced it, replaced thermo, replaced rad. cap. Rad fan works. After about 5 minutes of hard driving it starts to overheat. If I take it easy the guage won't go past 3/4 and if I cruise it stays cool. I drove to work and back without driving it hard and didn't overheat at all.

Water pump?
or could it be that the turbo is so close to the radiator, that after a while it heats it up too much.

I also put some water wetter in it and same results.

Re:Overheating again!
 

Damn that sux! Try running the fan from the battery, Hook it up to a switch or just .... like a said, set it to come on when the car starts. Maybe look into turbo wrap...???? Should also help w/ any lag you have. ;D

Re:Overheating again!
 

I've got the fan on a switch.

Anyone else had this probelm? I've got an all metal radiator, could it be that since it's all metal it's getting really hot and not cooling down the water/coolant?

Re:Overheating again!
 

my car gets hot if i keep it in wot for awhile. Im buyin a fluidyne radiator....---- single cor ebs

Re:Overheating again!
 

I had the same problem, I put a aftermarket radiator in the problem was solved.

Re:Overheating again!
 

Did you change your timing belt? If you did, your cam timing could be off by 180 degrees. This will affect your ignition timing, and overheating will occur at anytime above cruising speed.

Re:Overheating again!
 

if your running that eg radiator, i hope it is dual core.the single core one would not work for me.so i put a crx dual core radiator in my delsol.that thing don't get near half.plus the turbo and, oil cooler, water lines run to it.

Re:Overheating again!
 

I checked the timing and the timing is on.

I'm not running a half radiator, it's a full size metal one that I got from this guy. No leaks or anything.

Took it out today and got the rest of my exhaust hooked up. After about ten minutes of semi-aggresive driving the temp guage started to rise, so I put on the heat and didn't overheat again (even if I floored it). Sounds to me like it's just that the cooling system isn't up to par with the new turbo. What else could I try besides getting a raceing radiator?

Re:Overheating again!
 

Definately a shitty radiator. Have you looked into the half sized ones at all?

Re:Overheating again!
 

Should I try to get a dual core eg radiator? I don't want to spend more money and then realize that I need a racing radiator to keep up with the temps.

Found this, dual core all metal for only 100. Or should I suck it up and get one of these.

Re:Overheating again!
 

Ive been looking at those radiators on ebay. They look nice and Im considering buying one too. Anyone have one. Lets get some reviews...

It sounds like you just need to upgrade your cooling system. Are you running the fan constantly? When the car starts to overheat and you turn on the fan, do the temps drop?

Re:Overheating again!
 

whatever radiator you buy is gonna be real close to the radiator. If I where you I'd put a piece of that chrome looking heatshield paper that is used to wrap the ac hoses
on the spot between the radiator and the turbo. :'(

Re:Overheating again!
 

I have a thought, why don't you just pull the thermostat and try and do a few test runs like that.. might be the ghetto solution you are looking for.

Re:Overheating again!
 

Actually pulling the thermostat wouldn't help cause the thermostat regulates the flow of coolant so that it has time to cool down in the radiator, with no thermostat the coolant will constantly flow not cooling down like it should in the radiator. 8)

Today I was messing around somemore and when it started to overheat I popped the hood to see if some air would help it out and to my suprise it did! Mabye all I need is a hood scoop? Guess that big front mount is blocking all airflow. I'm going to look into making a ghetto hoodscoop right over the turbo.

Re:Overheating again!
 

fans that flow more air?
undercar modifications/plates to direct air up towards the motor?

I know someone with a turbo h22 g2 teg who has tremendous heating issues. he has stuff routing air up from the bottom of his car, and he also cut a very large hole in his CF hood where his manifold is.

Re:Overheating again!
 

I don't mean to sound like a dick about this one, but I think you're wrong on that man. The more water that flows the better off the entire cooling will be. Why do you think cars have thermostats? Cause if they didn't then the motors wouldn't reach full operating temperature and your heater won't blow out hot air when you need it to. Like I said, I don't mean to sound like a cock but I believe the pulling of the thermostat will help you in your flow situation. You could always give it a shot and see if it works for you.. maybe ever get a much colder thermostat.

Either way, let us know how your ghettro scoop goes, do a writeup of whatever mods you make.

Re:Overheating again!
 

I do not think you should buy a new radiator. Are you sure the radiator has sufficient coolant? Sometimes if you pour the coolant in too fast it creates air bubbles in the system. So, the coolant raises to the top of the radiator much quicker and give you the impression that it is full and it's not. One way to ensure the system gets sufficient coolant is to let the car idle, turn on the heat to full blast, and trickle-full the radiator. 8)

Based on all the things above that you have done/checked, and if you are sure you filled the radiator properly, it must be a faulty temperature sending switch.

Good luck. ;)

Re:Overheating again!
 

I normally squeeze the top hose a bunch of times to milk the bubbles out.. but just check it after you run it.

I think the problem is more then just amount of coolant or quality of coolant.

Re:Overheating again!
 

A nifty little trick i learned from some gay ass rx7 owners is to toss some washers under the bolts holding your hood on it raises the hood and has the same effect as a cowl hood on a mustang. From what ive heard its pretty effective to stop the overheating of the rx7 somewhat.

Re:Overheating again!
 

That is a very cheap and effective trick man. Look at the G2IC link in the main page weblinks and he explains how to do it on the g2 integras.. should be comparible to the civic.

Re:Overheating again!
 

Yeah, I thought the same thing, it does actually take alot longer to get to operating temps. But I've been researching on HT and a few guys pulled there thermostats and started to overheat, put them back in and it stopped overheating.

It does this cause the coolant has to have time to cool down in the radiator.

I'm definitly looking into the hoodscoop. i might just get a cheap one off ebay, paint it black, and glue the bitch right over the turbo. May not look good but whatever.

Re:Overheating again!
 

Just one more suggestion for you...from the looks of you car. i bet the radiator isnt getting enough air becuase your huge as intercooler is blocking the entire thing.

just a thought

Re:Overheating again!
 

90ZCREX, earlier I suggested you check the temperature signal switch which is located somewhere on the engine block. Did you check/change it? I have a strong feeling this is were your resolution lies. :)

Re:Overheating again!
 

Its right below the CAS. It a little sensor with either a green or white plug. I believe it cost around 20 bucks max. Try swaping it with another one if you have one. I had a problem with my cooling system and swaped that out, fixed the problem.

Re:Overheating again!
 

Well that goes against logic to me.. I don't argue the facts found on H-T but I sure as hell think that their theories are wack.. then again I'm coming from the old school to help people out. So assuming you stick with that theory, what about a cooler thermostat. Oh and isn't it going to enrich the fuel mixture if you mess with the operating temperature?

Re:Overheating again!
 

Ummm Im prolly a dumbass but wouldnt running a pusher fan on the rad take care of the intercooler blocking air flow to it and on alot of civics the rubber bump stops under the hood... cant those be screwed up and down to raise the hood giving you the cool air you need? Im also going w/ Quadnie on the lower temp thermostat. Try 160*.

Sorry to take the thread astray but I got a question for Quadnie. Were you always the mod for the forced induction board??? Dont remember you being so but Im pretty ------- oblivios most of the time.

Re:Overheating again!
 

Yeah, always since like right before memorial day. No, I came out of nowhere and Jeff made me a mod cause I'm good at helping ya'll suckers.. I mean brothers out.

Re:Overheating again!
 

The temperature signal switch wouldn't happen to be the one that's right below the dizzy and is one little wire going to it would it?

When I was changing the headgasket, I pulled the little wire out of that sensor, and just crimped it back on.

Re:Overheating again!
 

Well ---- me and call me aunt lilly. That is the temperature sending switch. It's too late now but I'll check it out tommorrow. Thanks for the advice guys.

Re:Overheating again!
 

I had to change the fan switch sensor on mine 99' si it's on the thermostat housing on the 99' si. I got a haynes manual for 96'-2000' civic, integra, crv and it shows where all those sensors are. I'm sure they make one for your car. You know what would look trick is if you cut the front part of the hood, the vertical part of the hood where the honda H is. Don't cut all of it of but instead
leave the bottom and side edges so that you have an open middle part and the sides and bottom edges make a frame.
Then put some flat black painted mesh behind the frame you just made and it'll help with the cooling and your car will look like it has a type r grill. Just a thought ;D

\_______________/<----bottom front part of hood with the center of it cut out.
