Guest 57Roadmaster75 Posted June 9, 2008 Share Posted June 9, 2008 I moved this from the Perf/Mod forum to here. My mistake, sorry.I had to replace the waterpump on my 57 Roadmaster 75. While I had it out I decided to do some detail work in the engine bay. I was wondering what the factory heater hoses looked like. Were they red or black? I also wondered if the fuel pump was painted, and if so was it black or green? If anybody has some good pictures of an original 57 engine bay that would be great. Thanks!Bhigdog repliedHoses were black. Pump was installed on engine bare metal, then the engine was painted. At least that's what I could infer from looking at lots of "original" junk yard cars......Bob Link to comment Share on other sites More sharing options...
Guest 57Roadmaster75 Posted June 9, 2008 Share Posted June 9, 2008 Thanks. I did manage to find a cast iron water pump. The cast iron one looks a lot sturdier than the aluminum junk that was on it. The impeller is steel compared to the plastic one that was on the aluminum one I took off. I noticed a lot of corrosion on the aluminum water pump and the thermostat housing/water outlet(I assume the aluminum water outlet is after market and the originals were cast iron). Galvanic corrosion I suppose. The old water pump also had the heater hose outlet, but was capped off. For an A/C car maybe?? Mine is not...sigh. The only option available on a 57 Roadmaster 75 was Air Conditioning and I got one without. Oh well, I sure look "cool" when I drive it anyway. Haha. btw, if you know of any sources for a cast iron water outlet please let me know. I've got a few junk yards to check. Link to comment Share on other sites More sharing options...
Guest 57wagon Posted June 10, 2008 Share Posted June 10, 2008 I have a question for you on your car...if you are running your original carb, do you still have the heat tube feeding heat into the choke on the left side of the carb? If yes, can you snap a few photos of how this is routed and send them to me or post them? Mine is missing, and I cannot find photos of any online. I have nothing to go by to make a replacement!

Guest 57Roadmaster75 Posted June 10, 2008 Share Posted June 10, 2008 Yep, still have the original Quadra-Jet with the heat tube going to the choke. It's a weird fitting that goes to the choke. Looks kinda like a castellated nut. I'll get you some pictures. Link to comment Share on other sites More sharing options...

Guest 57Roadmaster75 Posted June 12, 2008 Share Posted June 12, 2008 Here are a few pictures. My apologies about the quality of some. My digital camera died(funny they just don't like being submerged in water). So anyhow the recent shots are with my cellphone. Hopefully you can get the idea of how things were routed. I Know, I know. Had the car for a year and a half and it's still not clean. I'm working on it. Grin Link to comment Share on other sites More sharing options...
Guest 57wagon Posted June 16, 2008 Share Posted June 16, 2008 Cars Inc only list these for Chevrolet and there are several listings for the choke heat risers. Seeing as a 364 is quite different from a 283, does anyone have the part number from a previous experience that works on our cars? 57- thank you for posting those photos.

Bhigdog Posted June 16, 2008 Share Posted June 16, 2008 Not the CHEVY CARS Inc. The BUICK CARS Inc. The obnoxious Buick guys from Jersey, not the nice Chevy guys from out West. Cars inc. Buick parts....908-369-3666.........I wish one of those guys would change their name.......Bob Link to comment Share on other sites More sharing options...
RivNut Posted July 20, 2008 Share Posted July 20, 2008 The carb is a Rochester, but it's more than likely a 4-GC, not a Quadrajet. First year for a Qjet on a Buick was in '66. Link to comment Share on other sites More sharing options...
