Hello!
I am rebuilding a frozen 1.8 engine and found a thermostat with an opening temperature of 90°C in it. It works fine - but for the stock engine an opening temperature of 65-70°C is recommended Does it matter? New ones are hard to find or quite expensive. I won't drive the car in winter but we have mostly intermediate temperatures at about 20°C. In summer it's actually pretty hot >30°C. Thanks to global warming... BTW: I want to keep my flaps. There are lots of discussions whether they are useful or not. Please do not go into this again. I want them installed. Cheers! Malte |

They are important and the motor will cool better with them in place. The thermostat only helps when the motor is cold and allows the motor to warm up a little faster. I suppose you could install the thermostat with the cable a little loose. You just want to make sure that the thermostat expands enough that the flaps are fully in the relaxed state (as if the cable was disconnected) when warm.
