Vehicle running warm 360 la
Well that's funny, because I have four Stewart Components thermostats here that I bought just this year from Stewart. They're all still available right on their web site.
A few years back, all they had were the Chevrolet-sized part glued into a plastic or phenolic disc to adapt. It was pictured on the site, and upon both visiting and calling (they were customers of mine) I was told that was all they had available at that time. They must've reintroduced them in the meantime. I haven't looked in awhile. That's a beautiful thing, as is buying direct from EMP. Good folks over there.
That being said, $30 is nearly three times what I've paid for any of my NOS ones. Still, I think the design is worth the expense if you can't find NOS. It was important enough for Chrysler to specify and install as OE, as well as print and install the decal I posted.
@Dana67Dart, I think Milodon kinda has it backward. I'd go with the thermostat
first, for one simple reason: The thermostat is the primary restriction in the cooling system. The water pump can only really flow what the 'stat allows. Hence, with the higher-flow thermostat, a standard pump should automatically flow more. If the pump is trying to move more than the thermostat can flow the pump will cavitate, particularly in a non-bypass system. Cavitation is hard on pump components, especially the impeller. If the increased flow capacity of the thermostat doesn't solve the issue,
then consider a high-flow pump to use that increased flow capacity.
I'd do the 'stat first regardless: It's way easier and less expensive than a pump change!
