I plan on changing the coolant this weekend. Again
. Because it really didn't want to drain last weekend. The engine was warm but I'm thinking the T stat was not open maybe? It seemed that only the radiator drained because I only got half a gallon and I know there is a lot more in the engine. All other cars I have done were fairly quick to drain. Have any of you found a trick to get the block to drain? Maybe make sure the engine temp is >180 to open the stat?
Disclaimer: Yes, I know the system is under pressure when it is hot. I have a method and device to relieve pressure before opening the drain. Not my first rodeo
