Your opinions please

Hi,

This past summer I installed a 180F Fail Safe (http://www.motoradusa.com/products/failsafethermo/index.html) thermostat in my 89 Si. Things were fine for a few months then the car started taking forever to warm up. So I replaced it under warrenty with another 180f fail safe unit. I suspect the new unit may be going bad in the same way as the first. It's possible I have another defective unit, but are there any other factors that affect the rate our cars warm up?

My car has the original radiator cap, a older "universal" Civic radiator (came with the car and has auto tranny fluid cooler fittings), new hoses, and was recently flushedf/filled with new anti-freeze. Any ideas or information on the quality of these thermostats?

Thanks much,
John

just use the oem one

im with 91 civichatch2571 go with the tried and true method go back with a stock one.if it was good enough from the factory it shoulod be good enough to work now

Thanks for your replies.

I was leaning that way when the current unit craps out (again), it seems to be ok now but who knows about tomorrow....
