Want to take my 2010 Yukon XL Denali with 180,000 miles for a family trip from Michigan To Florida - Can you help me make this a success!

Thank you! Should I also be replacing the radiator hose at the same time or just stick with the hoses that go up to the heater core?

Definitely replace the radiator hoses if they're original. I'm sorry for any confusion there - I thought those were already on your list.

Everyone -

Thank so much for helping me and being so patient on answering all of my questions. You've given me so much to do and so much to think about.

No more questions until I get some of this stuff done or run into some issues.

Thanks for taking the time to respond to someone that knows nothing!

You knew enough to ask for help. And that puts you way ahead of the game.

Rock Auto has the AC Delco pump cheap, but I have also used Gates, Dayco and Melling water pumps in the past with great results. Melling is one of the OEM suppliers of pumps to GM. Remember to buy the thermostat if your pump doesn't come with one. Replacing the thermostat housing at the same time can also help prevent leaks, and many thermostats and pumps come with a new housing for that reason.


Everyone has their own approach that works for them, so I can only share what I do that works well for me. I don't worry so much about getting every drop of coolant out of the system. 95%+ of the old stuff drains out the moment you remove the lower radiator hose. So when I'm done closing everything up after repairs, I simply refill the system through the recovery tank with 50/50 dexcool premix, leave the cap off, start the engine and let it warm to operating temperature, adding coolant premix as needed to keep the tank from going empty. Once the engine is up to temp, I shut it off and refill the tank to the full line, then put the cap back on and take it for a drive. Then let it cool and add coolant back to the full line. Then I check it every day for a few days before I start it in the morning, adding coolant as needed. When I do it this way, I very seldom have to add any coolant after the first drive cycle, and even then it's only a few ounces. I've done this probably 10 times on my Yukons after various modifications and repairs, with no problems.

Found the ACDelco pump, but I don't think it came with the thermostat and housing - does this look right?

Yup, that's right!

yep, that is everything you need. you do not even need to use any kind of sealant or gasket maker, the seals are all built in or has o-rings.
when you install the water pump tighten the bolts in a x pattern, just like tightening lug nuts.
your going to want a to use a torque wrench. the water pump doesn't take much
@swathdiver should have the specs handy

+1. Tighten the water pump bolts as Wes says, but in two passes:

Water Pump Bolts - First Pass 15 Nm (11 lb ft)
Water Pump Bolts - Final Pass 30 Nm (22 lb ft)

Is this right for radiator hoses?

Yup! But remember, your engine is the 6.2L. In this case the part number is the same but that may not be the case for other parts.
