Replaced ECT / Sending unit / 180 termo ???

I agree that your fan could be causing a prob with high temps.

I lost that little plastic air dam under the bumper that directs air flow up to the radiator and my temps went up without it.

I also did this I had a hot condition, my thoughts are that the eec is picky with t-stat's as well and that the 180 is just a bit outside the range. When I first set up the tune with the tweecer I changed the temp setting and it has been rock solid since, and before I had the fan switch mod and had to keep an eye on the guage all the time.

I don't get it. Everyone says that the computers in our cars are very picky and while I agree with that, I just put a 160 t-stat in my car and it runs cool. No problems with the fan of the temp. I thought about changing to a 180 after everyone had a fit when they found out what I did. Now I just don't know...

I wouldent trust the stock gauge on temps. Go get a cheapo gauge from walmart or auto zone for $10 and see what it says.

My car seems to run better after I have done this. My only problem is My temp guage when i first start and warms up sits just below the O.

After I drove to work it got up to a little past M, my problem is i dont think the fan is kicking on. I spilled alot af antifreeze and sprayed out my engine bay with water after the degreaser.

I will try to verify the fan working or not working. I have never seen my temp go up that high before. But I wanted accurate readings, now i have them.

O and if i run a computer check for codes that kicks the fan on right?

good luck. I have been having problems with my temp/fan for 6 months. The fan runs sometimes and sometimes it doesn't. I have a 180 t-stat also, I'm thinking of going to the 160 now.

IF the fan is working intermit. you may want to check the grounds and stuff. I also had an issue with fans not working on and off. Turned out my block to chassis ground was going out and I didnt notice until it got to the point the car would not start. When I replaced it the fans worked like a charm.

The car may run cool with a 160 but the performance will suffer as the coolant temp also triggers fuel setting as well as spark (or something like that, I remember looking at a table in the tweecer that ran off temps), and you may also have some switching from OL to CL if it never heats up. I think the big issue with the 180 is its not as open at the lower temps as the 160 (which will stay open longer and sooner than either 180 or 190) but is close to the 190 just enough to cause some fan switching issues (not in sink for when needed to cool) as it thinks it has a 190 in there (that actually goes up to 210-220). But what do I know I am just thinking out loud on this from what I have noticed with messing with almost every aspect of the cooling system and seeing what it does.
