ARGG. Small leak at the Heater core valve. I replaced the washer but must have not been a perfect fit or something. For right now I was just going to drain it, I will never use heat in this car so I will take this on after summer. My question not being too mechanical.. Does the Fluid have to circle through the heater core for everything to work correctly or and I just Cap off the hoses going in and out of the heater core? Or do I need to just bypass it and get a longer hose to keep everything circlulating...
Thanks

A previous owner on my Pagoda inserted a manual shut off valve right before the 'real' one at the firewall under the hood. I close it in the summer so my heater is 'off' and my engine cooling works just fine. Come to think of it, I believe that original valve also shuts off the circulation to the heater core, so you should be completely fine if you block off the hose going to the heater core. Not sure if you then also have to block off the hose that comes from the heater core so no coolant can 'backflow' into the heater core, up to the leaking valve.
