- 2008 Mazda Cx-9
So long story short I bought a 08 CX-9 Sport with a bad water pump. After removing the engine and replacing the water pump. We installed and put new oil in the car. Started right up ran until it reaches operating temp about halfway between hot and cold and it died. In the beginning we could get it to start back up but now nothing. Car turns over just slightly fires the first time and won't fire after the first try. Checked all wires and plugs. Unhooked the battery over night to reset system. Checked compression before and after also hot and cold. Noticed the head closest to headlights was the same compression number no matter hot or cold. But the rear head was about 15-20 lbs higher hot after the water pump than before when I checked it cold. Seems like the coolant level hasn't changed. Plus the car didn't over heat the first time we started it after the water pump replacement.
Any advice would be awesome!
Thanks
Also what's the unused gray plug on the left side of the radiator used for?
