Thanks!!!!

Cool. But it doesn't work for me. I don't know why.
Edit... Yes it does! I swear, after your first comment on this I went and clicked the icon. Stayed blue, nothing happened. Now it turns red! I'm stoked! (OK, maybe I'm getting carried away....)

So would anyone here recommend replacing this Thermostat while doing a citric acid flush?

Definitely, after the flush has been done of course.

It doesn't work for me anymore??? Weird.

I've seen vehicles make FASTER trap times in the drags when hot lapping... i.e. running down the strip, turning around, and doing it again. These are gassers with modern SEFI port fuel injection...

I'm not a fan of low temp stats.

We ran mid 10 second times @ 130 mph, consistently, with this vehicle and that was with dual four-barrels, dual point ignition and a 4 speed gearbox.

Modern EFI cars require high coolant temperatures to get the ECM to go into closed loop...Robert

P.S. My recorded lap times at Willow Springs, Buttonwillow and Laguna Seca, when I made the switch to road racing this car, were all made with low coolant temperatures and all times were fast & consistent...Robert

Yes for closed loop... but they do not take until 180F+ to do so.

Oh FYI, my '01 truck goes into closed loop at 154F

Interesting....

Our 2008 Dodge needs 178°F to 186°F to go into closed loop...but, keep in mind, that's likely more of a ULEV rating effort than anything else.

Ironic...

I just installed an ECM/coil upgrade on a 2006 Pontiac GTO with the 6.0 litre engine and part of that package was a 160°F thermostat...Robert

Dr. Bert,

If your oil pressure drops when using the 60* then your oil is hot enough to release any trapped moisture.

heat destroys engines, cooler operating temperatures are desirable for longevity (given certain parameters).

I am surprised that you didn't notice a drop in fuel economy.
