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
