I've got a leaking heater valve in my 1993 240, and am waiting for parts to come in. The valve leaks externally a bit, but also internally, so heat is partially on all the time.
I would like to just pinch off the heater core hoses in the engine bay just before they connect to the firewall. Is this OK to do without looping? I know in 740/940 the cooling circuit requires circulation, but I think the 240's aren't affected by zero flow, which happens anyway when the valve is closed.
Am I remembering correctly? OK to pinch these off for a week?
