So over the last couple of months I know I had a small coolant leak and I discovered the upper small hose on the surge tank was loose and the tank was cracked so I replaced the tank, clamps and cap and I took the opportunity to flush my radiator for preventative maintenance since I hadnt done it before. (99 ETC 110,000 miles I bought it with 82,000).
I knew it was over due so I used a flush cleaner made by prestone and ran it for a day and a half and then put clean water in and then my problems started. Now I drive it for 10 miles or so and it starts getting hot and will eventually overheat. I found that it is leaking water from the overflow, so I replaced the thermostat and no change. ( I tested both thermos in a pot of boiling water and both worked). I used a combustion tester myself on the cap and it showed no results.
So my question is did I screw something up with flushing? Why did this problem start just as I flushed it? What else could cause high pressure in the cooling system if there is no exaust gasses? Previously I had no problems and I drove it 50+miles a day. I'm at my wits end.
I would just like some more ideas before taking it to a shop to have better tests done to rule out a headgasket.
