If your Thermostat is opening like it should, then one that opens at a lower temp won't help. Drive with your headlights or bumper lights on, and that should turn the fans on at a cooler temp. I think the thread you're looking for is for the FC thermoswitch. It kicks your fans on at 205F. I think the stock temp it turns on is like 220 or something, which is too hot IMO. How do your radiator fins look? Are you using the stock waterpump belt?

Yes, the undertray makes a big difference.

That shop owes you a new undertray.

Undertray makes a huge differance as well as proper ducting around the radiator. Air will always take the path of least resistance. When the air travels through the mouth of your car and hits the radiator, some of the air will pass though those small fins, however those thin little fins will also create resistance when more air is being forced through. When this happens a pressure wave builds up in front of the radiator and the air will reverse course and find the next easiest path out the vehicle. In your case the air will travel undernieth the bottom. In some custom installs it's usually around the sides of the radiator because people forget to install proper ducting around the radiator so the air isn't being forced through. Radiators are heat exchangers, so for them to be most effective, you need as much air to past through them as possible.

umm interesting i thought it would matter if u get thermostat that will open earlier r sure about that? oh umm i ll try to find that thread bout fc thermoswitch. my radiator is brand new i put it in just not too long ago, fins r fine as well and yes ia m using stock waterpump belt!
