So, a couple of questions cropped up. Will this make things difficult for a future smog cert needed for DMV registration? The noise is coming from the engine area in front, is that normal? I realize the exhaust goes from the engine, all the way to the rear and out. Just making sure, thanks.
Thanks man. I found a place to get a second opinion so I'm going to try that first but I'm getting nervous driving this thing around. I also lined up someone to help me do this ourselves if needed (water pump/thermostat).
ok good luck,, after thinkin bout it I would think that the therm or intake gaskets wouldnt leak while the vehicle not runnin and just sitting,, probably water pump!!! probably a good time to check/replace belts & hoses
Thanks. I will type up tomorrow on the puter. Too much to type up on iPhone. One question now though - it's leaking on the passenger side, so that should rule out the pump as you said it was on the driver side. And it leaks with the engine off, thus not using the pump. Is that correct logic? Does a pressure test "check" the flow to and from the expansion tank? Thanks so much for the help, I really appreciate it.
Ok good, thanks. I'm on the right track then. I'm calling the shop I took the wife's truck (even though they don't do diesels) to see if they can at least pressure test it. Thanks again for the help.
No worries man. Second opinion is the water pump. Could you help me figure out what brands I should be looking at? I don't mind spending more as I don't want to go cheap if that's not recommended. The dealer also recommended I replace the thermostat as well, do you recommend that? Thanks again for all the help, I really appreciate it.
Well, I got the water pump replaced. It ended up being a lot of fun and having the right tools makes the job so much easier. It took about 5 hours but I walked out only spending about $300 on parts. The gasket on the bypass pipe (from the water pump housing to the thermostat housing) was bad so I had to change that out as well as the little 2 inch water line feed hose. We didn't replace the thermostats as those were still working fine. I found a great website called dieselplace.com (just GMC/Chevy) and they had a step by step walkthrough with pics. It sure came in handy. Thanks again for all the help.
