heater hose blank off cap
On cars without heaters, does anyone have a part number or what did you use to cap off the outlet for the heater off the water pump. Its for a small block.

This was recently discussed at length. There are 2 options. There are rubber caps that can be installed on the outlets and held in place with a hose clamp, if the rubber bursts however you'll be parked. Another more reliable option is to remove the pressed in tubular nipple or cut off the cast one, and thread the remaining hole for a small tapered pipe plug. Chose the option that your abilities allow.

In the Help! section of Autozone called a Bypass cap. Though our preference is to remove it and tap and plug it. Some pumps you cannot do it though and will just destroy it. Another reason we try to use the Edelbrock pumps more often since they are thread in.

i found that if you take the end of the tube and crush it in a vise it will twist out with a pair of vise grips, they have some sort of sealant on the tube and it is just pressed in. you have to use a 1/2 npt tap then use a allen cap plug.

any concern about aluminium shavings damageing the water pump seal if you dont get all the particles out? take a piece of heater hose and put a bolt in the end and clamp down. Take other end and clamp to water pump. Not real pretty but works.

Mike Forte, a vendor here, has an aluminum plug you can use a short piece of heater hose to put it on the stock hose connection. The hose will last much longer than the rubber caps.

I just recently did this on a stock water pump. I removed the pump, got a piece of dowel that fit snugly and put in the tube. I then took a propane torch and heated the pump (not a lot) then I used vice grips and worked the tube until I could twist it out. Then I slathered a glob of grease on 1/2" pipe tap. I tapped the pump and pretty much all of the chips were held in the grease. I then cleaned up opening, took an air hose and blew it out. I wiped on liquid Permatex on plug threads and sealed it up.
