this might be utter blasphemy...but before you spend one dime....take off your front bumper and drive around to the same conditions it would make it overheat before.......see if it still overheats...if so, you know it's not ur airflow

 

ummm i have a percesion 350hp intercooler and i am pretty sure my fans are good but i will have to check to see how much they are rated at but i know they are not hooked up the the ac switch cus they are on even when the ac insnt....i havent had a prob with it running hot since the humidity has goneaway these last few days...oh and i running 11-12 psi of boost....and when i say its running hot i havent had a chance to put a temp gauge on it yet i have just been going by the stock gauges and it has never acutaly gotten all they way to the red but when its running reg temp it runs a little below the half way mark and when it gets hot it runs about 3/4 hot on the gauge or about a quarter past the half way point...again thats for all the help guys...im gonna start tryin a few differnt things before i jump off and buy a fluidyne

oh and i hope this isnt a stupid ? but my dad is an aircraft engneer and he was askin me if my half core would hold as much fluid as my fullsize and i was thinkin well duh no its half the size but his point is that he doenst think there is enuff fluid to cool the motor but everyone on here says the halfcore should work fine

 

Are you running coolant or water?

When I was running straight water I was having overheating issues. As soon as I added coolant the problems went away.

this may be true, unfortunately, all of us running larger, non-log manifolds dont have much of a choice when it comes to space in that area! kinda sucks. that is why i believe getting a fluidyne, witch has a bit higher capacity than stock, cant hurt.

 

look man i am an expert on heating probs cause i had a shitload with my car...I have a gsr in a 92 hatch turbo with peakboost mani. I dont have a/c but everytime i got on the interstate it would run hot. I went with everyone's advice and went with a fluidyne....installed it....same outcome. So i continued and changed the thermostat, water pump, and put water wetter...same outcome. Trust me when i say this. TAKE UR FRONT BUMPER OFF!!!!! I did it and lo and behold, ran perfect!! I had a shitty old scratched up bumper and cut a hole in it.....runs like a dream now. I mean what do u have to lose. It's free, and it will adress the air flow issue. If it's not lack of air through your radiator, then u know it's ur cooling system. So before u go spend money...run it without ur front bumper.

 

hmmmm thats a really good idea but if lack of airflow thru the bumper is the prob thats going to suck because i really dont want to cut the bumper....my intercooler is flat black and cant really be seein i like it that way.....dang sounds like i have a few different options to try

 

we're not saying make your car a DD without a front bumper.... just for a day or so just to see if the lack of fresh air to your rad is what's causing your overheating problems.

 

you should really get a temp gauge... preferably digital so you can see exactly how hot u r gettin...
If you find that your car runs much cooler bumper-less....take out one of your fog lights and/or turn signals and make some sort of scoop to redirect the fresh air at your rad.
Just make sure if you remove one of your turn signals you might have to put another one in a different spot to meet DOT/DMV regulations

 

if you take out one and it runs cooler you'll prolly want to take the other side out and put a scoop in there as well...really couldn't hurt
**** it really could only help...not only would you have fresh air upon the FRONT side of your rad...but you'd also have some cool air across the BACKSIDE of your intercooler...

 

you can always do the $10.00 sears job....goto sears and get some longer bolts, spacers, and some washers and kick up the windshield side of your hood...to let just a little more heat escape your engine bay
takes like 5 minutes with 2 people

 

thnx for the ideas fellas. those are very probable situations. i am going to look for a vented rad dam to throw on the bumper. i, like orion, need to paint my IC black anyway, so while its off im gonna figure out a good vent, alont with cutting out the grille in front of the IC. thnx again. it def. couldnt hurt

 

peep this link...hope it werx

It does work very well to controll uinder hood temps, you dont need to make it as drastic as i did, i used over an inch sized spacer, mines not daily driven and i wanted as much heat dissipation as possible. my underhood temps are really high with the top mount and alot of boost

 

got the same manifold and had the same problem. 2 fans one on the front and on the back, water wetter, and oem automatic Civic radiator. Problem solved

 

cool ****. hey in those pics, what ignition are you using?

 

Aem Twin fire, COP msd blaster ss coils

 

Replace your thermostat, it's cheap. Check for air bubbles, or lack of coolant in the system. Pressure test your cooling system at the radiator. If it leaks, you may have a leak somewhere internally. Do you see white smoke? Is your water pump leaking coolant? You may have a problem, so before you go buy water-wetter, and a new radiator, pinpoint the problem with the car setup how it is now.

 

thermo and rad is brand new and i dont think i have air in the system i think when i get paid im gonna get some waterwetter....can u get that a autozone or pepboys or do i need to order it...and if that dont fix it i will go from there...but i did like the hood idea jz98ctr i might i have try that later

No need to use water wetter, 50/50 mix should work just fine coolant/water. Used distilled water because it has a higher boiling point because its clean not like dirty *** tap water. Make sure you bleed the cooling system a few times, drive it and bleed it again a few more times liek that will ensure you get all the air out. If you have the heatcore still hooked up then make sure your running the heat all th eway hot and on high so all the air gets out of the heater core.

Propping th ehood up will bring your underhood temps WAYYYYY down. Thats why people do it, i did it on my car and it brought the engine temps down from 230 to 210 just because everythign isnt heat soaking anymore. And its a cheap fix for a mear 5-7 bucks work of longer screws, spacers and washers

 

now how do u think that would be if i proped the hood being that its my daily driver do u think it will make it easyer for theives to get in there and monkey around also what about water when it rains

 

well if you rpop it up a little, just enough for the heat to escape, then it shouldnt be an issue. My buddy runs his proped up and he drop through heavy down pours on the way to maryland last month with no problems. I dont drive my car unless its good weather, aka not raining, so i have mine jacked way up. as long as there is a little space so the heat can escape then your good to go

as far as theives well hondas are the easiest cars to break into. Takes about a minute. so the hood being proped up isnt going to make anythign easier, if they want to steel the car or parts off of it they will one way or another without any hastle.

this really has nuthin to do wit this thread but my boy lives in Pembroke Pines
used to drive a silver toyota celica with lexani dubz yo haha
had that cool thing in it that wouldn't let you start the car unless you blew into it rofl
lol he would drive and in like 15 minutes the car would shut down on him making him pull over to blow into it agen lololol
just thought it was funny

 

Propping your hood up like that will not make your car run any cooler, it anything it will do the opposite. That area below the windshield is a high pressure area. Why do you think the heater system takes its air supply from there.

I am running a half width from a 2000 SI in my hatch. I have one aftermarket slimline fan mounted behind the radiator, with my intercooler mounted in the front. My car will consistantly run 185 or less no matter the conditions. I have a stock T-stat and run straight water w/ dishwashing soap. even boosted I never get any heat into this car.

You need to bleed the cooling system and you need to check flow through the radiator. Off course you may have a head leak.

 

When it overheats does it fill up your overflow bottle? I use a funnel that has the correct size rad cap fittting to bleed and fill coolant systems. This way your able to fill up the funnel, and let the car run until it pulls all the fluid it can into the system.

Water wetter is a good idea, while still using a 50/50 distilled water/coolant combo.

I would definitaley do a coolant system pressure test as well.

 

no like i said it has NEVER overheated but the stock temp gauge goes up alot...when it is running at normal temp the neddle is between a little past the 1/4 mark and the half way mark on the stock temp gauge which is normal but on a hot day after about 1/2 half to 45min worth of normal driving the temp gauge goes up to about 3/4 hot on the stock temp gauge now i have never really let it sit there and get any hotter i would just turn the heater on and the temps would come right back down to normal temps....so next week when i have some time i am going to drain all the fluid and fill it will distilled water,water wetter, and 20% antifreeze and hopefully that will fix it
