What to do with heater core send/return lines ? I`m removing the HVAC system from my car. What do I do with the heater core send return fittings on the water pump? Do you just loop them? If so, whats a good way to do it being that they are two different size fittings?
Thanks.
Thanks.
Re: What to do with heater core send/return lines ? I went to Pep Boys and bought a 3/4 and 5/8 bypass cap. Thet are rubber cooling caps that slip over the barbs and just clamp them on.

Re: What to do with heater core send/return lines ? I was thinking of just looping it also but you would have to adapt for the size difference and I would think that adding some kind of coupling would create a possibility for leaks. Seems like capping the fittings at the pump would be the way to go.

Re: What to do with heater core send/return lines ? Any cooling differences by just capping it off and not removing the thermostat?
I read that the lines should be looped to help open the thermostat at the correct time.
