Overheating issue Im having a very intermittent over heating issue. I can drive around for a couple hours doing errands on a 65-70* day without overheating, then Ill drive around for an hour on a cooler day and start overheating. It doesnt happen every day, or even every other day. I cant seem to find any consistency to it.
My turbo is about 2 inches from the radiator but I have a blanket on it. Im running 2 12" fans;1 pusher and 1 puller. They are cheaper but were suppose to flow a decent CFM, and I have the blades set correctly as well as polarity. Im running the stock thermostat and have no ac.
I was looking at my tune and heres the fan settings:
Fan 1 On Temp:192
Fan 1 Off Temp:187
Fan 2 On Temp:206
Fan 2 Off Temp: 200
Should I start by replacing the thermo and the radiator cap?

OP, did you remove the plastic airbridge that mounts to the bottom radiator support? That thing is VERY important.

Ya the airdam is gone because after I hacked it up to let the intercooler piping through there wasnt much to it. I might be able to make one out of aluminum but I really dont think the air dam is the issue here though.

Also, if your fans aren't shrouded, also like they are from the factory, your fan efficiency will be greatly reduced. You lose alot of those cfms, alot.
160 t-stat and fans to come on at 185. I think thats where mine are set and I run cool as a cucumber no matter what...in 95* south Florida heat with my A/C running, in traffic. LT1 radiator, stock fans and shroud.

when you say overheating,, how hot its it getting? try a 160 stat? since your in alaska, i dont think the straight water is an option, but run the min amount of coolant req.
also, if your timing is really retarded, combustion temps are higher and can give you problems.

I;'m not sure what factory setting are...but from the factory the fans should go on and off together....and they always run on low and high settings..together. You need that one big hit when they come on. Shouldn't have them come on separately.

Itll get to about 220-235. Maybe 240 on occasion before I notice and shut it down. Timing is advanced not retarded.
Straight water is an option, it really doesnt get that cold here. By the time it gets cold, the car is in the garage for the winter.

The fans are only important while the car is not moving so it doesn't sound like that's the problem. That air redirector is VERY important though. Unless you've turned the car into a front feeder the car needs one. I assume you have a front mount intercooler as well?
By front feeder, I mean opened up the front grill, removed the plastic air shield in front of the radiator, and sealed off the area in front of the radiator.
I would definitely get a 160* thermostat. You fan temps were pretty good BTW. Good Luck.
My settings:
Fan 1 On Temp:194
Fan 1 Off Temp:186
Fan 2 On Temp:201
Fan 2 Off Temp: 196

Air dam is gone along with that weird plastic ****. I have no a/c so no condenser either, and the fans are mounted directly on the radiator. The bumper has been opened up but mainly for the intercooler. Im sure some of that air is redirecting up though.

There's alot of things going on IMO. No shroud, no air dam, fans not working TOGETHER, stock t-stat, fans coming on at factory settings.
....and man I used to be Anchorage every month for 8-10 days each month....its friggin cold there.....lol

Haha, its just so weird that it doesnt happen everyday. I drove around today for an hour on my lunch and it was much warmer today than yesterday. No problems.
Easy thing to swap....you'll be better off with a 160 t-stat anyway. Give it a shot. But make sure you reprogram the fans to come on earlier with it.

Ya, probably has the stock 10 year old tstat in it. haha
Should I go 160 or 180? Isnt optimal temp range 170-200?
