This has been a week of "Revelations" that, "In a Nutshell" encapsulate something like THIS:
(1) My DIL allowed her "New To Me" 2019 Jeep Grand Cherokee to continue in operation after having a Coolant Leak... and she drove it until it blew all of the *Stuff* RTF Out of the Coolant Reservoir and left her stranded.
(2) BOTH Batteries in the Jeep went side-ways afterwards and required a complicated R&R that would end up with having to completely R&R the Passenger Seat... just to get at them. In spite of the "Help" my Son rendered (Ahem...) this portion took Two Days while I UNFUBARed all of the unnecessary Damage he did by being too GEEDEE impatient from the Get-Go.
Unfortunately, he wound up making a "Dog's Breakfast" out of the Battery Thermister Wiring and Destroyed that Sensor Harness and the H2SO4 Gas Venting Piping plugged into both Batteries. THIS kept me Fixing, Creating and Soldering while acting like an "Ancient McGyver" with a fistful of Nylon "T" Fittings, some high end TYVEK Yellow Fuel Line... mixed and matched up with some other Silicone Hosing and clamps over the Entire First Day, while I was bent down over and inside of that cramped, Super-Secret Battery Well.
I stayed in there pretty much all during the day in order to *U-F* the Works down there and then be able to keep going on towards doing the necessary Engine Diagnostics... But... NOT having the usual Pro-Grade Diagnostic Gear I am accustomed to using and working with for such things on Late Model Vehicles made progress STOP..
(3) Meanwhile... I'm still intent upon performing both a "Relative Compression Test" ...AND... An "In-Cylinder Live Compression Wave Form Test" using my MICSIG Oscilloscope along with a 500 PSI Pressure Transducer to visualize any possible damage done to the Heads-Valves, etc. of this Truly Remarkable Well Built Chrysler-Fiat Designed 3.6L Pentastar V-6 DOHC 300+ HP Engine.
However, up until an hour or so ago, I was NOT in possession of any Decent Late Model Capable Bi-Directional Scan Tool outfitted with Guided Component Instructions and the ability to perform all of the requisite Chrysler OEM Engine Tests because I needed to DEEP SCAN THE 2019 JEEP FIRST.
(4) Ordinarily, the one I would want to get would be the Snap-On Solus Legend or the Solus Edge that sell USED right now as a Kit over on eBay with Snap-On's On-Line Updates already paid for and installed ranging from the 2018.4 level all the way up to 2024.4. HOWEVER...they ALSO seem to run in the Very Pricey Range of $1,500.00 -$3,000.00.
Man... THAT is a LOT of Bread (aka...The Elusive Spondulex)...!!!
(5) Well... Lah-Dee Dah, Ladies & Gents.... I kept checking eBay all last night and today and managed to find just ONE that has been updated to 2022.4 and was listed as Complete and Fully Operational KIT for only... $800.00...and so.... I *Pinched* it On The SPOT.
Guys... THIS Gear is a SERIOUS Professional Grade Bi-Directional Scan Tool LOADED with Features they take seriously enough at Snap-On to supply THESE YouTube Training Videos for Professional Mechanics ...So Keep Your Eyes Peeled ...and Scope out eBay Frequently enough to find Great Deals like THIS One!!!


I'll pick up the MICSIG Diagnostics over on the Oscilloscope Thread once I get past doing whatever the Snap-On Solus Legend points me towards with what might be going on under the hood...
PS... The Prior Owner must have managed to install the Oil Filter UPSIDE DOWN and it completely collapsed it ...making it By-Pass filtration for whatever amount of time THAT involves.
