Installing low rpm heater fix

[John I.]

Just finished replacing my leaky heater core and figured it would be a good time to install the Y-fitting that has been collecting dust in my garage for 7-8 months. I disconnected the return hose that comes from the heater core to the water pump in order to install the 1/2" brass plug per Heatercraft's instructions, but was unable to remove the barb fitting currently threaded into the pump. There's not much room to get a wrench around the thing, plus the threads look like they received a liberal dose of thread-lock and/or waterproof sealant when installed.

Any tips on how to remove that fitting from those that have done this mod.? Thanks.

Since you don't need the fitting, I wouldn't be shy about getting a pair of pliers or vice-grips on it. Unlikely that taking out the fitting could bugger up the thread in the block, but don't torque on it too hard.

A deep well socket should work.

A slight amount of heat aplied to the barb will free it up also, mini tourch. (slight amount of heat.)

You could use bypass caps for 5/8" hose.

Yes, it did work! Size was 7/8".

Thanks for all the great suggestions!
