Chevrolet Repair: cooling system, cooling system pressure tester, lbs pressure

Question
I'm having a hard time finding where about the cooling system is leaking anti freeze seems to be leaking some where between engine and Trans. Can't see it leak any where. 98 chevy s-10 2.2 Seems to leak more when heater is turned off.

Answer
HI ROBERT,IF IT IS LEAKING BETWEEN THE ENG AND TRANS IT IS A SOFT PLUG ON THE BACK SIDE OF THE ENGINE..MY ADVISE WOULD BE TO GET A HOLD OF A COOLING SYSTEM PRESSURE TESTER AND PUMP THE SYSTEM UP TO 15 LBS PRESSURE,THIS WAY YOU WILL BE ABLE TO SPEND TIME TO LOOK FOR THE LEAK. CAN BUY THESE AT ANY PARTS STORE OR TAKE TO YOUR LOCAL SHOP IN TOWN..BEING THE BACK SIDE OF THE ENG CK FOR HEATER HOSE CONNECTIONS OR BACK OF THE INTAKE MANIFOLD..I HOPE THIS HELPS YOU,,,TOM
