1G How I lowered my coolant temps 6 degrees!!!

[dnhieu]

yes your fuel trims wont move if the temps are that low. you need to keep them around 180 and above to do so. i know you can get a chip burned to get them moving at a lower temp but in my own opinion its still too low. i find myself latly just letting the stock setup keeping my engine cool. the fan kicks on around 210 and drops to about 190 and i drive in the mid 180s...

Is a 160 thermostat too low? I was looking tonight, it was either 160 or 180.

Actually, 180 is too low for a 1G but OK for the 2G. The coolant temperature must be above 190 for the 1G ECU to go into learn mode. In addition to coolant temperature, intake air temp must be less than 123, and barometric pressure must be above 22.9 inHg and below 31.6 inHg. If any of these conditions are not met, fuel trims will not adjust.
(Since getting DSMLink I learned that information I once believed to be true about 1G vs 2G coolant temps was false)

I don't get why some people say adding additives won't lower temps. Isn't that the entire point of them. Cooling system additives work by transferring heat more efficiently through the radiator = lower temps!
Either way, I found this link on a local dsm website and figured I should share it.

I put the thermostat in before I got a chance to read this, the 160 only delays the engine from heating up really fast. The engine still runs at about 215 while idleing, and about 210 while cruising. Im making myself one of your signature scoops tomorrow to get the temps in the low 200's.

What kind of radiator do you have?
Do you have a heat shield or upgraded fans?

you guys still having problems with coolant temps??? this is what SOLVED my problems in florida heat. i dont even run the fans non stop anymore in 100 degree weather in back to back traffic.

get a upgraded radiator and do your BEST to use a stock fan and 1 slim line fan. the stock fan cools 10x better then any aftermarket fan i have bought over the last 2 years and it turns on and off when its supposed to...

So here is my update. I'm in the process of installing my 2.4L and with everything off I figured I would try to rig up some ducting that would catch all the air lost after the FMIC. I used the stock ducting and cut it to where the bottom of the FMIC is sealed off. This blocks the 2-3" hole where air could travel under the frame instead of to the radiator. I also used some cut up heater hose around the edges of the radiator to help seal it off more. This solution is a lot cleaner/less ghetto than my last solution.

I was/still am contemplating getting a carbontrix vent. That would be a tremendous help I assume instead of all the turbulent air being forced under the car.

What is this cover for I took it off?

That's the air duct that forces the air coming in to flow through the radiator. Without it the air can bypass the radiator and you may overheat. The fans turn off when the car is moving over 45 mph and the cooling system is relying on air coming through the front grille to cool the radiator. Without any ducting system the air coming in the front will go around the radiator and not through it.

You can custom make new air ducts to fit a FMIC or use something like DSMlink to keep the fans running all the time. (or do both). Here's a link to how I replaced the stock air duct to fit my FMIC.

Don't throw those pieces away! You can trim them and use them as mounting points for the new air ducts.

Cool thanks man now I am going to have to make something for it because I don't know what ever happend to that part.

My bro run the stock upper cover just cut it to the topof the intercooler and wind splitter and was running cool. but to be safe he also has a fan on the back side of the radiator. never overheats.
