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!

A couple of close ups - I definitely have some type of oil leak somewhere. Most of the cables, tubes, hoses are covered in it. Also, looks like the one cap had a leak at some point.

Should I be trying to isolate the leak?

I started to reassemble things, but can still go back if necessary.

Probably just need a new power steering cap on that side. That kind of fluid loss we call sweating. Weeping is a little more, leaking is dripping onto the ground.

When are you leaving? Mine is basically ready. Have to make up some washer fluid, replace a remote and double check the air in the spare and then start loading it up.

Bought two CyberPower cigar lighter inverters that I want to test out so my wife can run her laptop for work if needed and my CPAP machine in an emergency. Bought a handheld CB Radio for the trip too.

I have a wifi antenna that is about the size of a VHS tape. It is powered by a laptop. it can be used in a vehicle, I believe the 'reach' is as much as 5 miles... in open areas.

I definitely have some spots of something on the garage floor as well. Just not 100% sure what it is. I was told years ago that I had an engine oil leak and a differential leak. But, I've also found over the last year that my local shop is not very trustworthy.

I leave at the end of December, so I have a little time left, but also want a little time to test my work. Still have a few things to do like rear shocks, see if I can get the spare down, fluids, need to check the engine mount, etc. Plus with travel for work, not around every week.

You have to tell me more about the inverter...I can see my wife going for that for sure.

Does that run on a cellular account?

Wifi only..... if you are parked somewhere, it 'should' pick up a signal from somewhere ( like a MacDonalds, etc)....

CyberPower M175XUC and M140BUC

Bought two for flexibility. Might use the smaller one up front or in the back, however they want to. I reckon the larger one will get plugged into the back of the console and rest on the floor next to the cupholder.

Oh almost forgot, have to put my phone holder back together. It sets in one of the cup holders up front and plugs into a cigar lighter and has its own USB ports for charging the phone with one leftover. Have a short power cord for the phone when this is set up.

For years we've had 2 2-port USB adapters, the higher powered models, they're in the console when not needed.

Are you running a dash cam? Been running one since 2019 and am bringing along extra cards to save video or take stills off it of interesting things along the way.

I use a dual cig lighter power. It folds upward, and is fairly out of the way. I like the 2 on-off buttons on the top, so you can keep it plugged in. I turn off the power at start-up, so no power surges. It also has an LED readout showing your voltage.

( like where my GPS is mounted...... below Sunlight, but still an easy view )

That's nice! One of the inverters is about that size and if used on the center stack, would protrude into the tray below unless angled up. Might grab that after people steal my other ones again! LOL



When I use this thing for the phone, wife complains about where to put her Yeti cup! LOL

My daughter has a phone holder that attaches to the silver panel to the left of the nav unit but blocks the view to the nav unit and seems too low for my eyes. Only using it for Waze since we have not been able to update our navigation maps since 2016 and GM refuses to allow Here! to give us new maps.

looks like it has not been cleaned in a long time so that makes it harder but the oil cooler lines are known to seep a lot and over time it can make a good coating all over the lines and the lower area in the front area of the motor, also could be the oil pan and the power steering pump doesn't look to bad just sweating a bit as james already noted.
things to look at for leaks are the valve covers and oil filter adapter area, oil pan, oil pressure sensor, valley cover, rear main.
you can spray some degreaser under it all over while at a drive up car wash and then pressure wash under it real good, then use some rags and wipe everything down that you can reach then drive it a bit and then get under it with a flashlight and look for fresh oil. the rear main can be checked by removing the inspection plate and use a flashlight and flexible mirror to see around inside.
