I checked the coolant level tonight and its SUPER LOW!! I had it topped off with water a week ago when I started diagnosing and fixing some things until I get around to doing a full flush with new fluids. It makes sense how all of a sudden the car temp spiked yesterday. So I guess we can confirm its burning coolant?? The coolant/water looked clean, clear and greenish though. Oil looks clean too. It looks a bit thin but I don't know what oil was put in the car. Also on the high side on the dipstick. The car is cold and its a little over the H on the stick.
I'm going to pull the new plugs I just put in a few days ago to see its condition and also do another compression test. Any other suggestions?
