Heater Hard Piping Delete Question

BTT

Anyone done this? I don't need my heater either, and thought I'd help clean up the engine bay by deleting the heater hard line and EGR stuff. I figure a plug on both ends will suffice. I'd like to avoid trial and error on the size if possible.

All you need do is take the hard lines and hose with you to the parts store once you get it off to avoid the trial and error. Then simply 1) cap the fitting off the water pump down under the alternator where one of the steel lines connects (or you could unscrew the barbed fitting on the pump and put a brass plug there), 2) buy the proper size bushing that screws into the manifold in lieu of the hard pipe fitting and also accepts the ECT sensor, and 3) buy the proper size brass plug to replace the egr coolant return line on the back of the manifold. Alternatively on the egr return line - that's located where it's very difficult to see once the engine's back together. You could simply cut the hose, insert a small screw/bolt of the right size to block it off, and clamp the screw/bolt in the line. No one will ever see it, and it will block the line off just fine. You needn't worry about the other end as the nipple is part of the hard pipe you're removing.
