Yes, i saw it on the picture, its an assembly. I guess i will put a new thermostat in (I have 175000 miles on the car). Its $25 bucks from ***************.
But first i will try to take the guts out of the old assembly and put it back, making it to just free flow. That way i will at least test for general cooling efficiency of the system. If it stays below say 80 all the time that would mean that i dont have other problems (like clogged radiator or block, improperly dilluded antifreeze, improper belt tension, water pump, fan cluch or whatever else may go wrong there).
So can anybody tell me
why it may be bad to run cooler engine?
I will put it back together for the winter...
Oh, and did anybody ever found a drain plug on the block on MLs? I couldnt find one last year...
Thanks
