Low Water Temps. ~160 Highway
Hi guys,
I have done a good amount of searching, but I would like some opinions on my exact issue. On the street, my car sees ~200F, but once I get on the freeway, after 5-10 minutes of driving, my water temps drop to 160, sometimes even to 155. I don't have any cooling mods save an AST.
On a side note, I recently installed the belly pan, and saw a temperature drop of about 20 on the freeway, but pretty much none on the street.
SO my question is: are my symptoms indicative of a bad water pump or t-stat housing? Or can there be some other issue?
Thanks,
-Daniel

I have similar temps. Are there "risks" to running too cool other than the time to warm up?
Highway will cool to 160 and pretty much hang there as long as you're moving at highway speeds.

By ambient, do you mean what is the temp outside the car? It was about 60 degrees F and very cold wind. I'm not sure how long a "while" means, but it takes about 10 minutes for me to reach 180 on the street.

The thing that makes me think its not the t stat is that my heater works fine. Or is that possible with a stuck open t stat? Is there a way to test the one I have without damaging it while pulling it out incase it's fine so I can re use it?

The problem is your sender location. I had a TB coolant line sender. It consistently showed much lower readings than my t-stat housing sender, and it was always on the freeway.
There is nothing wrong with your car, and you dont need to do anything ....... except maybe relocate your sender.

Thanks for all the insight guys. Adam, Before I put the belly pan on, my temps were between 180-200 highway - city. Now its 160 - 200 Highway city. I don't think its the sender, because I'm having 0 secondary boost on the freeway, and from what I've read that indicated that the car isn't warm enough yet (I have no boost leaks).
However the stock needle doesn't move at all, but IIRC the middle range is 150-230, so I don't know if I can use the stock one to judge. Is there a way to test the thermostat and re use it?
