Gates Gates OE Replacement Thermostat

Q:Does this thermostat stays open if it goes bad?
Crystal S.
A:BEST ANSWERHi Crystal, I'm glad to be of assistance to you. When the thermostat fails, it can either stay open or closed. If the thermostat is stuck in the open position, coolant flows continuously into the radiator, causing the engine to run cold. If interested in this part, use the link below to order at 49% off the regular price today while supplies last. I hope this is helpful.
