Waterpump: wait or swap preventatively

[alvocado]

Thanks for the part information.

I did something similar a couple of years ago to replace the leaking crimp connection on the transmission cooler line by cutting off the crimp and attaching new hose with step clamps. There's a flare on the tube end that helps lock the hose clamp in place. No leaks after two years. Your approach with the AN fittings is definitely more sophisticated but it got the job done for about $10.

It's exactly the same on that aluminum tubing above the rear axle. You can carefully remove the crimp and put a 5/8 hose on. I just like going a little bit more high-tech

My fix for the OEM crimped on transmission lines from 80,000 mi ago.

As for preventative maintenance, here's my brake job and whatnot I did for preventative maintenance, LOL

I did mine about 145k just because, I used a. millings. no clue how good it is.


this does remind me, I have a long trip coming up in September. I was going to replace fuel pump before going, but I should probably do a radiator too.

ugh always something haha

I have the rear 90deg fitting for the back laying on a shelf. got the part number off here, but never could get them off. looked around and never found any threads about those breaking and just forgot about them. it's basically only the front ones baking near the manifold during heat soak and the common unknown broke motor mounts that turn the front ones brittle and snap off.

I'll get around to it someday, but I'm pretty sure my radiator end tanks will break before that haha.

Those rear 90° fittings usually don't break. They're not getting cooked directly over the exhaust, which probably helps. It's the hoses that deteriorate.

I would recommend replacing the heater core quick connects at the firewall. I had one of those fail on my 06 Suburban and it overheated, almost to the red mark. Luckily no damage. This was about 4 years ago and I replaced with OEM.

Dorman makes metal replacements now for those. I just installed them on my 04 project Suburban, as preventative care. The original ones were very brittle. I also eliminated the quick connect that comes from the large tee joining at the coolant reservoir. It's kinda a pain because that connection is so tight once you remove the original one. I heated the hose a bit with a heat gun to get it to slip back in and used a hose clamp.

BTW, it looks like the coolant level sensor was eliminated in 05. My 04 does have the low level switch (as well as my 99 Silverado), but my 06 doesn't have it. :-(

Yeah, just replace the water pump. Make sure you use the aluminum/EPDM gaskets that mount to the block.

It's quite a surprising omission. My '02 had it as well, along with every other vehicle I've owned in the last 2 decades but these rigs.
