Well, I have an SOHC greddy kit and FMIC. OEM rad and fan.

Car has been fine for months, no probs whatsoever.
Now, the car is not bubbling-over overheating, it just just pretty hot at idle AFTER you have driven it for awhile. (a bit over 3/4's on the gauge)

It has not bubbled over the overflow, it just gets full to the top.

I replaced the thermo and cap. no difference. bled system and new coolant.
When I bled the system with the cap off I filled it to the top.
When the fan kicked on the coolant level dropped, indicating the water pump is working.
No leaks of any sort.
Compression tested all the cylinders, she's healthy.

When it is sitting at idle and starts getting warm, the fans are kicking on.
The temp will drop at idle if I REV the motor a little (like 2-3k rpm.

Not sure if I need a water pump, or a daul core radiator. (or maybe just some water wetter and prop my hood for that jdm rice look

THANKS!

 

I would try putting a new thermostat in it first. Either that or bleed the system for air.

 

^ he already did that

 

I would normally say replace your headgasket, but your saying it goes back down once it cools. I don't know... If you aren't hurting for cash, i guess i'd try a new radiator, just cuz that would be easier, and could be the issue. Either a dual core stocker, or get an aluminum one of ebay, no one usualy has complaints and they are cheap. Could be head lift under boost too.

 

well, like I said, it mainly gets hot when it's idling, not under boost.
compression reads 170-165 all the way across.
any other suggestions?
thanks guys!

 

just get an half size aluminum radiator from ebay for $100 and see if it solves your problem

 

If its getting hot while idling then it most likely isnt getting enough airflow across the radiator to cool the car down. If you are using an oem radiator and oem fan then your next step would be to get an aluminum radiator(fluidyne,koyo,mishimoto) and I would imagine that should solve your problems.

 

My B16A2 turbo does the same as this.It runs hot whilst going slow.My temp gauge never goes above half way,but the fan kicks in quite a lot more than when the turbo was not fitted.It's purely down to airflow through the radiator.I have a double core standard half size rad.
If I remove the front mounted intercooler my running hot issues go away,so I'm sure it's the intercooler obstructing airflow .I bet yours will be the same problem
one thing you could check,make sure your intercooler cooling fins are not blocked.Check your rad also

 

is your fan stock? If not make sure its wired so it pushes or pulls the air through the rad and not against flow.

 

well, I need one quick and the local parts store could prolly get a del sol one in a few days. would the del sol dual core work in my 99 Civic almost as well as a aluminum?

 

any other suggestions before I get a del sol dual core from autozone?
thanks agian guys for the input!

 

dont waist you money and just get a aluminum radiator from ebay for like a hundred bucks
aluminum will work so much better. stock plastic radiators suck
