dutchzcarguy Posted May 17, 2023 Share #14 Posted May 17, 2023 Another idea would be: put both inner parts of both valves in the one solution, you got 2 fly's in one hit!

Patcon Posted June 11, 2023 Author Share #18 Posted June 11, 2023 I'm not concerned about ruining it. Just too busy to get into the shop right now. Link to comment https://www.classiczcars.com/topic/68337-heater-valve/?page=2#findComment-654219 Share on other sites More sharing options...
HusseinHolland Posted July 4, 2023 Share #19 Posted July 4, 2023 I had a go at this, since I was waiting for the aftermarket 74627 valve to come. I replaced the body square cut seal with a Viton thick wall o-ring. No external leaks, however the valve doesn't fully shut - the I/O hoses still have warmth to them, indicating some passage of coolant. I'm going to switch it out for the 74627.

I think those valves never close very optimal anyway.. Link to comment https://www.classiczcars.com/topic/68337-heater-valve/?page=2#findComment-654812 Share on other sites More sharing options...

I think those valves never close very optimal anyway.. That is true - I'll have to check it after more than 20 minutes driving. I had left the valve open for about 20 minutes outbound drive, to make sure there were no air pockets, then drove back with it closed. My experience with other cars is that with the valve closed the hose on the output side of the core will be cooler than the input, the I/O still felt pretty even in temp. I'll check it again. 1 Link to comment https://www.classiczcars.com/topic/68337-heater-valve/?page=2#findComment-654817 Share on other sites More sharing options...
