Leslie, I had that heater problem with one side, it was the heater valve

I started this thread by whining about getting a seal for my water pump which I changed and all was good. Now just under a month later the pump is squealing so have had to send for a new one. Really difficult to pinpoint the culprit. Stops after a few minutes, thought it was the secondary air pump, disconnected that but still there, took the a/c belt off, no joy. Main belt and it stopped.

Belt tensioner starting to go ?

Thanks Henry noted , will see.how.it goes but will need sorted by winter or.it will be a cold sit
Annoying when you changed the waterpump and the noise is back soon after , I get a squeal on moderate acceleration often when I move off to get out a junction which disappers instantly If I lift off which I believe is the front rubber mounted main crank pulley , it doesn't wobble yet but I believe the rubber is slipping under high loads maybe something to look into for you as water pumps rarely give bother.
