Better cooling fans/radiator?
I had the same overheting problem while ideling, and after I drived it cooled.
It was without turbo, and it went on for 2 days.
The oil and antifresse didn't mixed but after removing the head we noticed very small leaks on piston one and three.
A good way to test is to start the car while cold, with the radiator cap off, accelerate hard a few time to about 4000RPM and if the coolant shuts out or circulates in the radiator viguorously it means that the engine compression is leaking through the coolant engine compartment.
It may be only small enough that the coolant doesn't get into the oil.
Also in my case I noticed that the antifreze reservoir overflowed only while driving hard.
I will have to upgarde to a new radiator soon and I wonder how much thicker a Koyo radiator is compared to stock.
And how will it fit with a custom turbo on it.

Supermex, that was not my problem, my problem was there was absolutely no airflow at a stop with the fans running, I tested that by putting my hand behind the radiator... I felt nothing.
Put the better fans on, now my hand moves back about 2 inches from the air flow when they're on, and no more overheating.

Cooled down a lot, now when the fans come on at idle, my coolant temp according to my datalogger drops 10 degrees celsius in 15 seconds. Seriously. That's about 10 times faster than the stock fans could even before the car was turbocharged. My a/c is a LOOOOOOOOOT colder now too.

here's a pic of my BUSTED OEM radiator...u can see where it was leaking from...soon as your pour coolant in, it would come out right there at the bottom where the rubber part is separated kinda....

Rep Power: 305 Forced induction usually strains the cooling system a lot more. Both in the added restriction and in the added heat inside the compartment.
Things that usually help are lower thermostat and fan switch (keeps coolant flowing more and turns the fans on earlier). A bigger radiator, as the OEM is not usually enough and more coolant and more fins are always better. And high flow fans do wonders during idle or traffic.
A really good reason to add either a oil temp or water temp gauge to the mix. The stock gauge is little more than an idiot light, meaning it only goes up when it is almost too late. Seems customers always complained that the stock gauge jumped around too much. So manufactureres put in a circuit that limits the stock gauges movement.

The past few days ive also had a issue with my car keeping cool. When i would sit idle at a stop light or something the car would over heat. When i drive then it cools down, like others on the board. So today i drain the coolant, add fresh water and antifreeze. Take it for a drive and it is still overheating while idle. So the next thing i do is go get a new thermostat. That doesnt work either the car still runs hot at idle. The fans come on like normal, so i didnt think that that would be a problem. Car still over heating at idle. So the next thing i did was unpluged the thermostat sensor, and put a piece of wire on the 2 plug contacts so that the fans would stay on all the time. Then i drove around for like 30 mins to an hour letting the car idle for 5 mins or more at times and the car never overheated while idle. So im guessing that the stock fans are insuficient like riceburnrex said. Until i can get some new fans, ill just keep them running all the time.

Rep Power: 0 Sodjazero, one thing you can do that may be a little better than just using the piece of wire is to get some relays and switches (about $5 worth) and make a fan-on switch for when you need it. You can then turn them off when it's cool outside and you're not overheating, and when you're running on the highway. If you get the right relays, the stock ECU can still control the fans, or you can have them come on whenever you want. I can show you how to wire that up on Sunday and what relays to use if you want.
If you're interested, we may still have some of the FAL fans, same type that I used. I'll check and see and if we still have some, check on a price for ya.

Anything that will help, thanks. But it looks like i spoke too soon. I went to go pic up money from my friend, I was stitting at taco bell, the next thing i know the it starting heating up after like 7mins. Slower than than the normal overheating phases but it does overheat still. This is really starting to pi$$ me off. Any ideas? But i def am interested in fal fans, what ever i can use to keep this thing from doing this.

Rep Power: 0 You need better fans or a better radiator... that's about all you can do except remove your intercooler.
The FAL fans will definately fix the problem, I'll check into price and availability tomorrow for you.

In short, FAL does not make some directly for our cars but there is an application that fits with minimal modification.
