Hi –
I am changing over my crate motor to a clockwise water pump, and a mechanical fuel pump eccentric. I will not be running a heater in my car so I would like to remove the heater hose fittings, and replace them with a plug of some type. I’m sure others here have done this, so I am looking for some advice.

1. What is the best way to remove the stock hose fittings? I have mauled one pretty good and it does not seem to be going anywhere! Should I use heat? Do I need to drill them out?

2. What should I plug the holes with? Tap for screw in fittings? Can I use a freeze plug with some sealant?

If you did this mod, please let me know what worked for you.

Thanks! Scott

I would run a heater. It will keep you married or help get you married. If deleting the heat, cap the intake but keep the bypass and cap or tap the other fitting. I am always amazed that anyone north of Tampa would not have a heater, free feel good on a fall night. Cheers Richard.

You'll need the one fitting which connects to the thermostat housing. Without it no water will circulate through the block when the thermostat is closed.

Does anyone have a good picture of a waterpump set-up for no heat. Thanks

no heater on mine...Sunny San Diego :D .

rock solid temps, no issues with overheating. Mustang heater bypass hose ($6 at Autozone) to the thermo housing and a cap for lower line.

don't mind the dirt on my motor...

Like mentioned you need to keep one fitting in the pump for the by pass hose. It goes from the t stat housing to the water pump. Sometimes they will come out useing a large easy out or vise grips to break it loose and twist out with the help of a hammer. On one I had to cut the tube off flush with pump housing then use a hack saw blade to cut a slit the lenth of the tube remaining in the pump.Use needle nose vise grips to twist out the remainder of the slit tube. Once done tap with a pipe tap and plug. Some have used freeze plug or hose cap to block off.

If you can get the tube out of the pump with it mounted to the engine you're in good shape. We used a freeze plug so we would not have to worry about taking the pump off and cleaning metal shavings out after taping. A 3/4 inch freeze plug fits perfect in the lower hole.
