Homemade Underbody Wash

I was looking under my truck today to see how the running boards are attached (I want to remove them). I noticed that everything is just covered in dirt/gravel. It is caked in some spots. So, rather than pay $10 for a car wash that includes a underbody rinse, I was thinking of either making my own out of PVC pipe and the garden hose, OR just hooking up the hose to the oscillating sprinkler.

 

Question 1: Has anyone here made their own underbody wash system?

 

Question 2: Can anyone think of a reason why a person would NOT want to put an oscillating sprinkler under their truck and let it run for a while?

 

Question 3: Does anyone have any other recommendations as to go about removing this dirt/gravel?

Ive been using a oscillating sprinkler for years under the truck to wash the salt away just dont turn it up real high.

The automatic carwash I go to has a serious underbody high pressure wash when you drive in. It sprays high pressure water from rocker to rocker under the vehicle. I always drive through very slowly and it seems to keep the underside of my vehicles pretty clean. We don't have salt here but I've never had any ill effects from the high pressure after 7 years of using this wash weekly on all of my cars.

I use a sprinkler to clean the underbody of my lawnmower. Granted it's not a truck but it does a great job nonetheless.

A sprinker such as that would work for the road salt build up, sure! I like that idea actually. You could make an underbody sprayer with some PVC.....but I imagine that an oscillating sprinker will have the same effect.

 

Though for the caked-on dirt and gravel (question 3)...I tend to use a pressure washer, or a standard hose spray nozzle with a high velocity stream. After winter, I throw on my greasy clothes, climb onto the creeper, roll under the Silvy, and spray every nook & cranny of the undercarriage. It might be overkill, but it works for me!

 

Good Luck!

Yeah...I figured there would be nothing to worry about...except maybe the duration. I am going to take it to the car wash first and have it loosen everything up, then go home and finish up.

 

Wow...I never thought of using a sprinkler...that's a great idea! :sigh:

 

PM me and I will let you know where to send the check...

does the sprinkler really work all that well? I would have thought you'd need high pressure to get the caked on stuff off..

 

We shall see...

 

im going to build a really intricate contraption and post a build thread on here for everybody.

 

Like a 'Rube Goldberg' sort of thing?

Just have the wife or a friend lay on the ground in front with the hose upward and drive slowly over :sigh:

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
