Series 62 vs Coupe De Ville

Started this discussion. Last reply by Russ Austin Aug 30, 2018. 7 Replies

What’s the difference between a Series 62 and the Coupe Deville? Looking at the Vin decoder it looks like Series 62 comes in a convertible and the Coupe Deville does not. Is that the only difference?

"What Russ said about the coolant crossover.  Dont force it down or it will crack. There should be some slight down pressure while compressing the o-ring, this creates the seal. You should be able to seat it almost by hand pressure ."

Water pump leak

I’ve posted on this before but can’t find my post or I’d comment on it. I had a machinist replace the nipe on the return and it still leaks from around the o-ring. The o-ring is good and snug around the nipple but when I put it in the hole in the water pump it seams a bit large. It doesn’t fit perfect. I’m thinking the o-ring is crimped and the OD is leaking. Any advice? I got the o-ring from a local auto parts store. I’m tempted to use silicone around the o-ring I just don’t like doing that.

Water pump crossover leak

Posted on July 23, 2018 at 4:40pm 11 Comments

I’m trying to fix the water leak problem on the crossover at the top of the water pump. I was able to get a new O ring. It leaks when I’m filling the radiator without even having any pressure. I got a new seal from the local auto parts shop that is for this year and model. I’ve tried putting a washer that fits in the top of the water pump to put pressure.

The car is a 63 Coupe De Ville but it has a 64 429. If the previous owner used the crossover from the original motor, which from I’ve… Continue

The car is a 63 Coupe De Ville but it has a 64 429. If the previous owner used the crossover from the original motor, which from I’ve researched was a 390, would the crossover work. I have a machinist looking at it and trying figure it out.
Any info would be much appreciated.

Where do the flashers go in my 64 Deville Convert.  I'm thinking that's why both turn signals stopped working.

Source for Motor mounts and Trans mounts 1964 SDV

Posted by Norman Silverman on January 9, 2019 at 4:23pm 2 Comments

Hi.

Where is the best place to purchase good quality motor mounts/trans mounts for my 1964 SDV? I see that Rock Auto has them for $8 and change, and others for $24 and change. Big difference. Is there a better place to buy them from?

Thanks

Fuel loss in Carburetor

Posted by Ian Osborne on December 29, 2018 at 11:24pm 16 Comments

Lately if I haven't started my '63 in four or five days it seems that the carburetor has gone dry. The starter cranks for an extended period of time and the engine doesn't come close to firing. I have resorted to pouring a little fuel into the carb to save the starter and battery. This gets it started and it runs fine. It also starts fine after sitting a short while - a couple hours or so.

The fuel pump is new and there is always fuel in the glass bowl of the fuel filter. This, along…
