I case you don't know about them, here is the story of the Moto Rad, FAIL-SAFE Thermostat (see above). Please give a few minutes to review the video on the thermostat that can only FAIL in the open stage and can never over heat the engine! These are not new and have been out for years. Made in Israel and under go lots of research and development. Sold by most of the top chain auto parts stores and mail order sites. MotoRad makes regular units to match OE models also.


The Problem: They have a large coverage for the US and foreign markets! BUT they don't have units for the later 4 cyl. Ecotec engines. Below is their latest model but does not cover 2006 and later engines. I'm on there mailing list (you can sign up too for it) and will let you know when they have the FAIL-SAFE Thermostat for the HHR. If you need a Thermostat for another car or truck I suggest you consider one of the FAIL-SAFE Thermostat.
Just to be safe.... FYI Regards, JC

Yeah, I've used these on one or two of my SBC V8's the problem is when they fail, which was about 2to 3 months old, they didn't last long at all
