oh by the way, i was checking around but wouldn't mind a definite answer - what are the rules concerning filling the coolant?
I know no cold water when the engine is off and hot, it should be running if you are adding anything while it's hot. Otherwise wait until it's cool to add the fluids.
Should i be filling the resevoir only? or also the rad?
Can i add coolant to the rad while the car is running? is it safe to remove the cap?

Thanks for all your expertise...

And ya that's a damn clean engine...
