Hi Dan.
I did use my laser thermometer to check when I did my first check run after my rebuild. It ran for about 1/2 hour outside on a day about the freezing mark with heater not connected. Thermostat housing was about 185° but my dash gauge was just off cold. My gauge has no markings. Too much salt on the road for a proper test run. In the past I have seen my gauge go to hot area when it was low on coolant so the temp sender seems to work.

I wanted to know about plumbing for the deluxe heater as I had removed it to correct the temp control cables. Prior to this I had no leeks.

So today after reconnecting the heater hoses and thermostat housing, I refilled the rad.
I thought all was well until I found coolant leaking on the floor. Not from all the hoses. Seems to be leaking out of the heater. Arrrgh.

I had flushed the core before reconnecting the heat cable. Seems that I did something wrong and maybe buggered the ranco valve.

So tomorrow I’ll have to pull the heater out again. Such a painful job. Hope it’s a simple fix, though it probably isn’t.

John.

When God gives any man wealth and possessions, and enables him to enjoy them, to accept his lot and be happy in his work�this is a gift of God. He seldom reflects on the days of his life, because God keeps him occupied with gladness of heart. Ecclesiastes 5:19-20
