? about tstat and rad flush
A couple simple questions. I plan to flush the coolant system on my 91' 190e 2.6 this weekend. After draining the crappy coolant and flushing the system with water, I close up the system, fill with water, add my bottle of Zerex Super Flush and run the car for 6 hours. During the 6 hours with chemical flush in the system do I leave the tstat out or reinstall it?
Also where is the engine block drain plug on a 190e? The picture I have of this is so poor, I can't really tell where it is?
