Hi, 1994 SPi, I have been having trouble with the heater, after following a load of threads here, Im now 99% sure the issue is with my heater core, so Im going to replace with one of the higher quality brass pipe ones..

Anyway, while "servicing" the heater valve, the floating type which sits up by the wiper motor, I noticed that on operating the cable/plunger the gate which restricts the water flow doesnt fully close. It looks like the valve is always allowing approx 20% of water through. I dont think the plunger is jammed, seems pretty free, didnt want to force it, but I just wanted to check if this is normal or if I should replace the valve too.
If anyone knows Id appreciate it.
Thanks!
