I usually roll my eyes when I read about how this particular brand of vehicle requires that particular brand (usually OEM) of part or it just won't work "right".... but your experiment is consistent with my experience with thermostats. I only buy thermostats from the dealer. I bought a "fail safe" tstat from Canadian Tire a few years ago because it was the only one they had in stock. The parts guy said "those don't work very well, you should probably order a different one in". I thought it was silly, surely it would work in my minivan. Well, it overheated within days of installing it, and the temp would nearly redline every time before it opened on the first run of the day. I promptly tossed it put in a Mopar one, and it's worked perfectly for years. For that matter, the mopar one I took out was working fine, but it looked original so decided it should be replaced while doing some other service. Go figure.

so a good thermostat is is the one that opens more? i to did a thermostat test with a new mopar one and an aftermarket one.
and the aftermarket one opened faster and opened more. the mopar opened less. so does that mean the aftermarket one is better?
both were 195F thermostats. i went ahead and installed the mopar one with a new water pump and my temperature is at about 200F

I think, most cars do not block short circuit, so part of coolant goes back to block w/o going to radiator. Question is ratio of coolant going to radiator/block.
Here is double action thermostat, it closes block flow, so 100% goes to radiator.
It has 2 discs. http://shop.advanceautoparts.com/web...023%7CL3*15971
