[QUOTE="notagt, post: 16052476, member: 176670"] Hi guys, been awhile and I have an issue. I have a Term motor in my Mach 1 and thought I had a radiator coolant leak out back driver side of motor, leaking down block onto top where shifter cable goes into housing. Never really noticed till I jacked up front end.Long story short, I have been doing coolant flushes after replacing EVERY part of coolant system and notice coolant level in my intercooler resvoir keeps dropping (one time earlier ICT climbed and I found tank empty).I have been reading threads and don't think it's the actual intercooler since no smoke out tailpipes or engine stumbling..idles perfect. Where could this be coming from to be leaking under the rear of the car? Still may have overheat problem I can't trace...car temp fine until I do one hard pull in boost, then temp climbs to 225-230 and doesn't want to come down..changed water pump, radiator, fan, 160 thermostat, iron block cleaner, 10 water flushes, new cap (though it's on a Morose metal tank and wonder if it's a thread issue).I can burp properly and I seem to still get air in system..passed leak down test and combustion gas test..thought where leak was it may have been rear freeze plug..now not so sure since IC tank level keeps dropping.
