ideas on cooling

[1BADVAN]

I have a 2.5L minivan and I am having trouble keeping it cool. Any ideas on radiator upgrades or other ideas? Thanks

all the factory shrouding and splash gaurds in place?

Is you heater core plug it wil give you weird over heating problems too.

Define not keeping cool?

Rad upgrades are hard to do without a custom rad, and it also depends on how you have your IC setup.

An oil cooler will help and its cheaper than a new rad.

+2 on a blocked or internally coated with gunk heater core, they run hotter and more inconsistant.

I agree with Simon about your definition about "keeping it cool." If your not reading the coolant temp sensor with a scan tool or a mechanical gauge your being mislead. My mechanical gauge and coolant temp sensor disagree about 5 degrees. It's too close to care who is more accurate.

If you need a mod to run cooler I'd say oil cooler. Mine cooled off my engine about 20 degrees here in the valley of the sun.

Flush the system

WaterWetter by Redline

Use the least amount of antifreeze possible when making your mix, dependent upon the coldest temps the car sees.

Oil cooler isn't a bad idea, I'd make sure you have a Oil Temp and Pressure gauge though after installing one.

Higher flowing / more efficient fan(s)

Also, if you are running an underdrive pulley, ditch it.

Toss in a new thermostat. I'd stick with a 195 unless you have revised fan schedules to take advantage of a 180 degree stat. Also, drill a small hole in the top of it and when installing make sure the whole is on top.

I'd try all of those before I'd try an aluminum radiator or a thicker one.

Agreed on everything but the 195 stat and UD pulley. The 180 stat is almost a necessity with TD's, even with a stock cal, they run so much cooler.

I've tried the UD pulley back to back with no difference in coolant temps noticed. :thumb:
