I need help with a big problem with a over heating and keeping coolant in the reservoir tank please help .it will build up pressure and u go to drive it it leaks out the over flow hose .
read previous answer 12 min back, maybe you did, if the cap is holding pressure and still throwing coolant as you rev the engine the pressure is exceeding the rated 16 or 18 pound cap and throwing it out. and that only comes from the combustion pressure ,not pretty ,try this with a good sealing cap when cold start it and squeeze the top rad hose, while reving the engine, if it pumps up its combustion, normal warm-up doesn't pump up for 4 or so minutes
