LSx Water Pump Heater Hose Fittings - Possible to Tap for NPT?
Is there sufficient meat in the water pump boss where
the tubes for the heater hoses are to remove the tubes and tap for pipe thread? Alternatively, do any versions of the pump have tube fittings that point up and forward instead of to the passenger outboard side? Thanks, Ken R. http://image57.webshots.com/157/3/64...3Rglzon_ph.jpg Photo credit - CHarris85Vette . |

this as well for my swap another plumbing project. I got some ideas, came back and started looking at his pictures of the WP. While he has solved the immediate matter of creating a hook-up, I know we all would like to revisit this when time permits. In the image here, the upper part of the boss simply looks too thin to take a thread. The bottom looks so, so. I've had three or four ideas about how to tackle the matter. Wouldn't it be nice if GM has already rearranged the fittings for another application like, say, the CTS-V. Failing that, some swapping, fabrication or even machine work could solve the issue. I've got a question for you on an item related to the same adventure. Watch for your new thread in C4 Tech - coming soon. . |
Comments anyone?

Does anyone have a crap pump that "we" could experiment with?

ck out Katech for the different tstat housings, this should get the hose pointed in the right direction
the pumps aren't cheap, next time I get a spent pump I ck out the how much casting is there |
water pump
How about heliarcing the piece in. I did it with a Summit radiator I adapted to my Trans-am. You can buy an aluninum bung with the female pipe size threads you need and have it heliarced at any welding shop. It cost me $15 to have the bung welded into the radiator which is thinner than the waterpump housing.:thumbs:

http://image58.webshots.com/58/7/32/...3NxdkEK_ph.jpg http://www.katechengines.com/street_...assemblies.jpg connecticut. Thank you for the tip about Katech's straight neck thermostat housing. I think this would provide the bottom hose with less interference at the frame horn. tiojames. Welding aluminum bungs would work. I think they perhaps have a larger OD than the width of the WP casting at the top tube, but it would be a simple matter to fill in with weld around the back side. http://www.bakerprecision.com/images/818006.jpg BTW - Your suggestion led me to think about whether Earl's 90º fittings with tube sections could be welded in place. Either modify something like this or build (bend & flare) from scratch and then weld into place. http://www.bakerprecision.com/images/997106.jpg Wait a minute. Instead of bungs or tubing, why not just weld aluminum AN fittings to the pump?? If someone took a 45º cut off the heater hose boss so the fittings could angle upward, so much the better. Earl's offers 'Male Weld Fittings - AN Thread' from -4 to -24. Another idea (that I've just discarded) was to use rectangular bar stock to make a block that bolts onto the heater hose boss. The block would create a 90º change in direction with inlets on one face that intersect with tapped outlets on an adjoining face. It would bolt to the water pump (after removing the OEM tubes) with a gasket or o-rings for sealing. Welding bungs or tubes with fittings are all probably simpler approaches. Thanks again for the help !! Ken R. . |
Pull out the steel tubes and drill-tapped to the next size up NPT. We just did one on our WC car. It worked prefect.

Those are some good ideas guys!
I've got another waterpump back in the storage room that I'll eventually get around to modding in some way :cheers: The thermostat housing really isn't a problem in the C4... it JUST clears everything with room to shake. but that straight fitting is very nice looking! |
