Mystery leak ?
OK so i have replaced the radiator cause it was rotten. Left it pressurized overnight and had no visible leaks anywhere (visible on engine or underneath)
Drove less than 5 miles & got a hot stall. I have that problem narrowed down to replacing the CPS tomorrow.
Get her back in the driveway Friday afternoon & by Saturday morning there is a puddle of coolant the size of a buffet platter underneath the driver side of the engine.
Cylinder leak down & pressure test "said" no cracked head or head gasket btw. Oil is clear & no white smoke or any other indication of a cracked head or gasket.
My question........ is there anything on the drivers side of the engine that could be leaking coolant? Like a drain plug or something? It's dry around the coolant sensor.
And here's the kicker....sometimes she'll go for a week or more & not leak then all of the sudden there's a puddle underneath the next day???

Yes, there is a coolant drain in the left side of the engine, if I recall correctly. But it would be strange to cause such an 'intermittent' leak from it, I would think.

Yep that's what has me stumped right now. I don't understand why the leak isn't constant.
But it's a renix.........maybe that's why.
I'm getting close to using my last stick of dynamite & end this saga once & fer all.......
