Personal automotive journey musings vol 1
Posted a year agoSo i hadn't updated the journal here for a year or so and i figure its about time to do something with this. I'm going to use it to post about projects and what's going on as it happens and since its mostly Cadillacs, well that's relevant and hopefully i can spread some info to y'all Cadillackers that i had to hunt over hill and dale for.
So what's up with B!tchFvck (my '92 Sedan DeVille)? Why hasn't shi been on the road for a while? Well, dear reader, that's because the power steering went all powerfully heavy on my way to the dentist last week. I checked the fluid, mint. Checked for leaks, nothin'. So I've been waiting on a Power Steering Pressure Switch and finally got to the store to get one today. It was snowing (!!!!!) so when the kid said it had to come from medway by tomorrow i said that's fine. Not like i was getting under there to replace it in the snow. But now i'm the proud owner of two jackstands starring bruce willis and some carb cleaner for another upcoming maintenance project.
Shi threw some error codes when i checked, and there's not as much about these as i'd like to see online so here's the rundown
E40 = this is the relevant one. On the datasheet it claims "open power steering pressure switch signal", so basically the thing's blown and i've gotta get under the car and replace it. Gonna hold onto the old part for tinkering latering
E48 = "EGR system problem", the datasheet says. This is an issue i'm familiar with as its been sort of periodic but now i know more than i did the last couple of times. We'll talk about this at a later date.
E91 = "PRNDL switch problem" which wowza i thought i was just pulling the thing wrong but nah. Lmao. Not a huge issue but still wanna get it sorted.
F48 = the refrigerant is low.
F51 = this one is about the computer, an BCM and EPROM read error or something- basically its the issue that makes the AC blow room temperature and switch to economy mode on its own. I'm not sure if this is something that develops from having a low refrigerant level, or if it tricks the F48 to go off, but its been doing this a while and step one is to refill the AC juice and see what happens.
So that's that for now. First chance i get i'm getting that pressure switch in there and rolling.
Additionally, a lil buddy of mine recently had their first classic car accident. Obviously everything's okay. The damage looks worse than it is by a huge margin, but the poor pup is shook. I've been around that bend before and every one of them has been built back better (and more moi) than before. So that's also on my mind as i write and assess. I'll be on board when they give the OK that they also recognize the condition green all around with their loved ones and friends who love and care for them and are willing to help. In the meantime, i'm calling up my time in autobody and my own garage to be ready.
Now, if you'll excuse me, I have some wrenchin' to do...

Cadillac HT4100 service laserdisc archived!
Posted 3 years agoFor anybody who has a Cadillac with the HT4100 series engine, this is a valuable resource! Shows an entire teardown and the process to replace components. Meant to be played in Cadillac service centers to train technicians!
The HT4100 AKA Cadillac's "High Technology" engine, was introduced in 1982 after the stop-gap solution of the much-maligned-but-technologically-fascinating V8-6-4 cylinder deactivation engine when the national fuel economy guidelines were introduced in the early 1980s
This engine went through several versions including
The original 4.1
The 4.5
And the L26 4.9 in 1991, the engine in my '92 Sedan DeVille.
This engine series if mounted transversely to accommodate the cars' front engined, front wheel drive configuration.
The HT4100, through all its forms, was applied between 1982 and 1995 and in models including the DeVille, Fleetwood, Eldorado, SeVille and Allanté.
In my personal experience, the L26 4.9 is a dependable engine that lets you know if its having problems in advance of the problems becoming serious. Some symptoms I have had experienced misfires and lagged acceleration. If you experience these issues, come back to this video because it will be useful to remedy any issues deeper than replacing the spark plugs, rotors, and belts.
The majority of the time, that is, while the engine is functioning, you'll enjoy responsive, peppy acceleration, smooth long-distance driving, and quiet, reliable functionality.
