Re: Simple question Econoline Van, What Tstat to use.
If you're moving south, you can install a 180F and shouldn't have any problems. The difference is that slogging down the highway the engine will run a bit cooler, but around town, especially running A/C and other power accessories it'll stay upwards of 195F.
I had a 180F installed in my Durango to keep temps in check when towing, but come winter, I had to reinstall the 195F as the cabin wouldn't get above freezing here in Ontario!
