I attempted a search and was not able to find a thread that provide the answer

I have an automatic, 03 ALH, which I installed the Frostheater in last weekend. I plugged it in overnight, got down to 32 last Tuesday. In the morning, nothing.

I read that there may be an inline thermostat on the autos. If that is correct, can someone explain where to locate it. Also, are there any changes I need to make to keep the fluid from leaking once the inline thermostat is removed?

Thanks!

Since the Frost heater depends upon convection, you need to mount it pretty much level with the middle of the block, if I remember correctly.

Funny, I had the same issue this morning... Installed it over the weekend, it kept it hot when I plugged it in at 190 but this morning the car was dead cold... I was already late for work so I did not check further to see if the heater was warm but the large coolant line was not warm at all.

Maybe I didn't set my timer correctly... Will check back later today to see what it does...
