Hi i recently installed my turbo. right now its at 1 or below 1 psi because i took off the intake pipe. However my car over heat. anyone know whats the reason why or what cause it? i change my thromstats/waterpump not to long ago. we added half water er about 2/3 water and coolant i believe....not sure. however i am going to drain and put fresh coolant to see if it overheats still. anyone have any idea? also the check engine light comes on...
