[Heater core question]

I've never worked on a car to this extent. I see a lot of u guys are doing frame offs and going all out. I pray someday I can do the same. As for now, I am happy to get the ball rolling with hopes to just drive the "old girl".

As for rust issues on my car, its not so bad. Yes it has some (especially in that heater box)as all cars do but its been a Cali car. I found the original owners service log in the glove box. It shows it was bought in Huntington Beach. Why do u think is a factor on whether or not to go thru the firewall?

Good luck with your build. Sound like you are a lot closer to finishing then I am, as it will be years before I am done

Don't take my build the wrong way lol I am doing things on a budget. You are prob doing things the right way (frame off). Not me...wish I could...I am just doing what it takes to get her on the road. She has been sitting for far too long (13 years). It felt good when my 17 y/o daughter came home from school and saw I pushed my car into the garage to start the wrenching process. First thing she did was open the car door and started reminiscing on when she would ride around with me when she was 3-4 years old. Now I hope to give her her first driving lesson in a huge open lot with my Riv

So I'm sure your build will look a lot nicer than mine

I am so new that was my first issue. His first paragraph had a blurp about going thru the firewall too lol. I figured I was working on the engine compartment & going thru the firewall seemed like a better idea. Good article with the pictures and all. Does every issue of Riview have articles like that?

[Speedo Cable and Antenna Firewall Grommets for '65]

Didn't see what I needed at Mr. G's, but rubbertherightway seems to have the antenna grommet, but I don't see the speedo cable grommet - where did you see it?

Im sorry for not getting back to u sooner. Im such a newbie that I havent got this forum ettiquette down yet.

Ok now, when u go to that website. Type in your vehicle info & navigate thru as if u are gonna order a free catalog. Once your there u can click on the "download PDF" catalog & wha-lah on page 4…both grommets u need on one page. Let me know either way if u get them. I ordered stuff too. I'd love to talk more 65 Riv with u. That is what u said u had right? I just started working on mine. My goal was to get her in drivable condition by Xmas. But finding tons of speed bumps along the way…heater core & brake booster issues today. So it looks like early next year might be a bit more realistic lol

[Heater core question]

I wish I wouldve heard from u sooner I followed the "thru the firewall" method written up in the ROA website. You were right about the rust, yuck! I had a sever case of rust in my heater box. I cleaned it up as best I could. Anyhow, I have a new heater core now & found the same problem with the shorter inlet/outlet tubes. It turns out there are two diff heater cores, one for Riv's with A/C & one without A/C. My radiator shop was gonna swap ends too. But I found the new one is half inch shorter in overall length. Where did u get your new core from? I might order one from CARS tomorrow. I am pressed for time now with the holidays & my engine schedueled to be done soon. I wanted to clean up the engine compartment. I am considering buttoning up the heater box without the core inside of it & finsh painting the firewall. That way I will have a reason to go thru the dash at a later date and do the thorough cleaning you recommended. How long did it take u to complete the job?

I am in the middle of replacing my heater core right now. I recommend you do it from the inside. You will be able to clean and paint the heater boxes that way. Yes, boxes. There is one inside the other. I found mine to be all rusty inside because Buick only painted the outside of the outer box. The rest was bare steel. Yes, it is more work, but you will be glad you did.

Also, I found the pipes on the new heater core that the heater hoses connect to were too short by about 3/4". I took the old core and the new core to my local radiator shop and they swapped the end tanks for me. This gives me my original heater hose connections again.

Good luck with it.

[Speedo Cable and Antenna Firewall Grommets for '65]

Did u find the grommets you need? If not i found both for you at less than $12. rubbertherightway.com has a ton of cool stuff for us (cheap too). Unfortunately, i havent ordered anything from them yet. So i cant vouch for their quality. I have a short list of part i will be ordering from them tomorrow.

[Heater core question]

I found it RivNut. Thank you very much.

There are articles on the Riviera Owners Assn. website (link in my signature) that describes both ways of removing the heater core - from the inside and from the outside. The article on engine side removal goes into detail on how to reassmble it so doesn't leak and is not noticeable.

[Heater core question]

Hello fellas,

I am new to this forum thing. I have a '65 Riviera & I sent her 401 out to the machine shop for a rebuild. I've owed her for about 20 years & shes been sitting for 13ish years. While the engine is out I was gonna pull the heater core thru the firewall. Thats when I learned it doesnt come out that way unless I cut a 1/4 inch around the opening. My question: if I cut it out will the core now be floating/rattling around in the heater box without the metal that I cut to hold it in???

[sidemount wheel well coatings]

I was planning on trying the rattle can rubber undercoating stuff on my wheel wells. Not sure how it would hold up to scuffs from the tires if they rub it. I would guess its not durable enough for that kind of abuse. But who knows...

Any recommendations for a coating for the wheel well? Am thinking it should be some type of tough coating that resists rubbing of the spares.

Thanks in advance, Tom
