Hey Everyone, The AMC 360 in my CJ 8 is giving me a hot problem. It's got new hoses, belts, 4-core radiator, flex-fan and stock-replacement water pump. I had in a
195 t-stat for winter heat, and it's been getting hot lately. The mech. temp gauge would wander up to 210, and it's barely cracked the 70's here in PA. Even cruising at highway speeds it would barely go below 200. I did some checking, and with the engine running and rad cap off, there's barely any coolant flowing. Crank the throttle and some flows, but not much. Today i put in a cold t-stat (160) and drained the coolant, put in Prestone's rad flush, and filled with water as per the bottle. I drained and refilled with water three times. The last time i even used the flush-kit with a garden hose to pump fresh water throughout the system, and it all came out clean. I was hoping to see some crud from a blocked passage or something. I put the coolant back in with a new bottle of Water Wetter. Still not much flowing. The gauge is a little lower, but when i hold the throttle, the gauge climbs again. The fan is good, you can feel plenty of air pulling through the rad. I've worked in the parts business long enough to know "new" parts can be bad sometimes. Does this sound like a bad water pump?Thanks, Don W
