    Dimension IV size of whitewall 1.3"
    Have the same tires.

I also need to replace the compressor, and have someone find a possible refrigerant leak. I don't mind not having AC, but no defogger is just a hazard when it's cold out.

    Rear window defogger has never worked either. Would love to fix that, but electronics really aren't my strong suit. All I've checked is the fuse. I've dreaded having a go at the back window, because a previous owner had the three rear windows lightly tinted, and I'm not sure how to go about removing the tint without breaking the defogger strips.
    Tint can be removed with a hand held steamer. My brother-in-law bought one at walmart and add water, plug it in, wait till warmed up, and hold
    up against glass and it'll release steam/vapor and it'll loosen it and you can peel it off.

    Wow the whitewall looks more like 1.5. What size are the tires themselves? Also are their any other specific measurements for them? I really like the way they fit in the wheel wells. Thanks!

    Re: Project thread: 1979 Coupe DeVille Phaeton (a thread 7 years in the making... kin

    Thanks for the tip! I have one of those Shark steamers at my parents' house. I'll try that.

    Yes, the tires in all of those pictures are a set of Dimension IV 215-75-R15 1.3" whitewalls. I absolutely loved those tires. I bought them new off eBay in late 2006 for $300 + shipping. The whitewall was dead-on correct for 1979, they made the car a time machine! By the summer of '13, they were dry-rotted, and the front tread had taken a hit due to an unnoticed worn-out center link.

    This was taken right after I repainted the crests in '07.



    Right after the tires were installed



    I replaced them with the set of Runway Enduro 75s that are on there now. (below) The Runway's whitewall isn't the same, it's about 1.1" wide, and drawn about 3/16th closer to the rim. They also have the wide serrated band in the sidewall just outside the whitewall, which catches the light, and is anachronistic for 1979. It dulls over time, but is very noticeable when the tires are new, or you ever put tire dressing on them. Painted crests faded in the six years since they were touched up.



    The Enduros are also discontinued now... They were about $350-400 installed, and have great traction. Yet, when you compare it to the picture above this, it's just not the same for me. The only place to get correct 1.3" whitewall tires at the time of writing this, is Diamondback Tires, which are about $920 for a set..Ouch! Do not buy the American Classic 1.3" whitewalls if you want a factory correct look. The whitewall is much too far out on the sidewall to be correct. It changes how the proportions of the wheel/tire combo work together visually.

    Is that a tach or temp guage? Did you install it or was it installed prior to your acquisition?

I sorely miss my '79 Brougham. I'd happily surrender my '92 Brougham d'Elegance to have another '79!

    Cadillac_Fan: Thanks! What you see under the ashtray is a temp gauge. It was installed when I bought the car. Power to the light + ground is split off of the ashtray light. Power is supplied by a wire running to the fuse panel. It stopped working soon after I bought the car, when investigating, I found that the wire had come unplugged because it was just stuck in next to a fuse. Open question What would be the best way to supply power to the gauge?

    It actually caused me a bit of trouble, because whoever installed the gauge put its temp sensor in the hole for the vacuum switch of the heat riser (EFE) valve, and rerouted the vacuum lines so that the heat riser was held SHUT whenever the car was running blocking the exhaust, & creating a hot running condition, as you could imagine. I ended up just bypassing the whole heat riser system.

    The hood ornament has indeed switched back & forth, good eye! The Phaeton came with it's original crest, but the plastic was peeling from one corner, and it was badly faded/yellowed. I decided I wanted to replace it with a fancier wreath version, and justified it because I had already put wreaths around the door locks (like the one in Goodfellas had). This was in 2006, and it was on there until Feb '13. Suppose I just got tired of it.. I'd ended up with a couple of new looking crest versions, so I switched it out again.

    I actually removed the plastic from the original, and repainted it to go on Denice (she had none of her own). It looked good for a summer or two before it faded out again. Ahh well.

    Original



    Painted for Denice



    NOS wreath & crest from a Brougham




    Bro-Ham: Thanks for the reminder on the blower relay! You're probably right. I replaced a couple years ago, but forgot how common it is for them to blow on these cars.

    Exclamation Re: Project thread: 1979 Coupe DeVille Phaeton (a thread 7 years in the making... kin

    I'm having a problem with the remanufactured brake master cylinder I had installed last summer. Pretty much the whole time it's been on there, it has leaked an increasing amount of brake fluid from around the resevoir cover gasket. Especially towards the rear. At first, it was just an annoying thing in the back of my to-do list. I'd add a bit of brake fluid now & then, and kick myself for having a shop install a reman unit when I was crunched for time, instead of rebuilding the old one myself!

    But the leak seems to be getting worse. I was extreamly displeased recently, to discover a puddle under the car, and a good portion of the chassis under the master covered in brake fluid. I took the car out this evening, and in the space of less than an hour it left a 8" puddle in the parking lot.

    The strap seems to hold it down tightly. Gasket is present & intact. The resivoir casting is a little corroded at the seal, but not bad where it's leaking, and the leak started before the rust formed.

    What I can't figure out is; if it's the top gasket, how is it leaking when I'm not driving the car & using the brakes? I wonder of it's also leaking where the master meets the booster, but I can't tell because there's so much fluid coming down from the gasket, lol! Ugh...

    Anyone have an idea about why ths is happening or how to fix it? I'm probably going to replace the whole cover next. Because this one is an oddball, the gasket attaches differently than my stock one, and I can't find any gaskets that attach the same way.

    Because this is not ok...

    Unbolt it from the brake booster, there is nothing connected between and nothing should spill. clean it up, let it sit and see if its coming from the rear seal. You can sand the top of the casting down with a block sander and get a new cap/gasket.

    Re: Project thread: 1979 Coupe DeVille Phaeton (a thread 7 years in the making... kin

    I think what you're seeing is actually in the casting, but i'm not sure why it's there... take a look at the top, you can see the line I'm taking about. The center of the rear actually worries me a bit, it looks bent slightly. Regardless, I'm going to replace the cap with one that has an original type gasket retention system, and take it from there.



    This is actually the way the gasket was installed when I bought the MC... I'm pretty sure that's upside down. Definitely didn't help the leak, nothing to catch the geysers that come up.

    Re: Project thread: 1979 Coupe DeVille Phaeton (a thread 7 years in the making... kin

    You're last pic suggests the problem. The gasket isn't seated correctly and so isn't sealing. Remember that brake fluid is hygroscopic (it absorbs water), so if the reservoir isn't sealing, air and moisture are getting in there, and the fluid is expanding in volume, even at rest, thus overflowing through the poorly sealed gasket. Return the gasket to it's original orientation, flush the system, and then see. Bet your leak goes away.

    Good luck, Ben!

    Re: Project thread: 1979 Coupe DeVille Phaeton (a thread 7 years in the making... kin

    You may be right there. Although as a good sign, I haven't noticed the level of brake fluid fluctuate any after I've been driving, or sitting hot, etc. Meaning I don't think it's expanding / contracting other than the obvious slow leak depleting it. If I pop the cap off right after I've been driving, it's the same level as if it was cold.

    I ordered a new cap & gasket that have the original gasket retention system, and a new bail wire. It's a chrome cap... only kind I could find. I don't mind the chrome, just hope it isn't flimsy. At least it looks more like my original in the pic.

    In the research I've done, apparently it's pretty common for remanufactured master cylinders to have gasket leaks. Has anyone else found this to be true? This one is a Bendix From O'Reilly. I thought Bendix was good. Seems like it rusted pretty fast, too.

    Well, new problem.. Yesterday the phaeton rolled over 235,000 miles & promptly had a "mental breakdown". We think the flywheel may be the culprit. I was driving around running errands, and I started to notice the engine making a slightly pronounced grinding whine under throttle. as I was pulling through a parking lot, it got louder, and started making a scraping noise even at idle. I looked under the hood, thinking it was probably a pulley or something, didn't see anything so I went inside & let it cool down for about half an hour. when I came back, I checked the fluids, belts, etc, and started it. I didn't hear anything so I drove away. it soon started making the scraping noise again. I was at a light & heard little pops and clicks coming from under the hood. got a block down, pulled into a parking lot. while looking for a spot, it started shuttering constantly & sounded pretty rough. I got out & listened around. sound was coming from the lower end, near the back of the engine / front of trans. I had it towed home, and here we are.

    I bounced ideas around with ga_etc (Austin), and the tow truck drivers. general consensus is possibly flywheel / flex plate. trans was rebuilt less than 10,000 mi ago. engine never as far as I know...

    I'm thinking this might be the red flag that convinces me to get the whole engine yanked out and rebuilt with cad company / mts parts. however there's no way I could do that myself due to a lack of skill & tools. so I'd have to go about finding a shop I can actually trust... which is no small undertaking. any thoughts on any of this are highly welcome! what would you do?

    Remove dust cover/shield under the trans and you can visually see if the the flyweel is cracked by turning flywheel with the use of a screwdriver amd you'll see where its bolted to if there's any cracks around that area. My 79 has it, check youtube, I posted a video of the sound. Is it like that?
    Search 1979 cadillac flywheel, or something like that. Lol

    1980Coupe,

    I found your video. Mine sounds different, it has more of a constant whining / scraping sound. Here's a video I shot to try and diagnose it. You can hear the noise very well close to the end, when I shoot the camera under the car. Does this help?

    Almost sounds like the flywheel cover is rubbing on the flexplate/TC. But unbolt the TC from the engine, start it up and hope the sound goes away.
