KA24DE-T overheating

[IchigoFace]

ever since my car had turbo its been overheating. i had a water leak around my water pump, so i had to fix that. its obviously the turbo but what can i do about this? the only thing i can think of to keep my car cool is to have the secondary fan 'on' at all times. is this a good idea. if so, does anyone know how to rewire the fan?

hopefully you are not running to lean because that can cause overheating. also use colder plugs.
other than that. your one your own. put another fan in if need be. change the radiator to a bigger own. change the thermostat.

How can you tell that you're running too lean, or too rich?

Well... there is common sense, an exhaust gas temperature meter, and an air / fuel ratio meter.
Common sense: running 10psi on stock injectors you will be running lean.
EGT: &nbsp;Temp rises as you run lean, and cools as you run rich.
A:F: &nbsp;Just look at the pretty lights. &nbsp;If they go too far one way... you are either rich or lean.
Also... you can hear detonation, caused by running lean. &nbsp;And you can check your spark plugs kinda often, because you can look and see how your combustion chamber is.

How many miles does your engine have? &nbsp;It could be a blown headgasket... I had a mysterious overheating problem until finally it was diagnosed (they did test but it came up as fine..replaced entire cooling system).

You can check your plugs to see if you're running lean as well. If they're white, your lean.
You didn't mention where you live, so we don't know if you're overheating in 40 degree weather or 85 degree weather.
You haven't mentioned how you are overheating, like during stop and go traffic, or traveling on the interstate only, or all the time, etc.
Do you have a turbo "kit" installed or a DIY turbo setup? I've seen some people who DIY put the intercooler right in front of the radiator, which could lead to heat soak.
Have you checked your thermostat? It could be frozen.
On your turbo kit, did you install the coolant lines for the turbo correctly? You could be disrupting the flow of coolant through your engine if you did not.
When you did your turbo, did you remove the clutch fan and fan shroud? Those help tremendously for cooling purposes.
And finally, are you just going by the gauge in the cluster, because it's very inaccurate...
These are just couple ideas, albeit some are very unlikely.

Blow head gasket
Frozen thermo.
Cooling system
Small crack in radiatior that you can't find
engine lean: White color or a hint of light brown.
Should look like: Spark plugs sould be a coco chocolate color
If Lean: increase fuel ratio/per psi of boost
Or lower the boost.

i got it fixed, thanx anyways guys. i bought a new coolant reservoir and the nipple on the reservoir was supposed to be drilled. so the problem was that there was no way for the excess pressure for the coolant to escape. at the same time it busted my water pump making it leak then causing my car to overheat.
