Overflow Tank Restoration
Anybody have a trick for returning the white expansion tanks to their original color after they turn brown/yellow. This part has not been available for years and and due to it being a 73 only tank I doubt anybody will repro it. Thanks Chuck D

Re: Overflow Tank Restoration (Fevre)
I used a 74. Not a direct fit but works with a few screw hole modification.

Re: Overflow Tank Restoration (chuck d)
I have been looking for a fix for the yellow plastic for ages but no luck. So you stay with the original but yellow tank or get an incorrect but white tank. Oh what is a perston to do :cry

Re: Overflow Tank Restoration (chuck d)
I could never get mine clean so I replaced it 4 years ago. I think I ordered it from Dr. Rebuild out of FL. I may replace it with an aluminum overflow tank this winter. Now you guys have me wondering if I got the replacement tank for a 74. Rod

Believe that the good doctor did have NOS tanks for the 73 but that stock is now depleted.

Re: Overflow Tank Restoration (Red73)
The 74 is not a direct fit so if your's did fit direct, I bet it is the 'correct' one.
BTW Is that a H2O temp gauge in the intake? Nice touch. No more peeking inside to see the temp while working under the hood.

Tom, If it's the correct one for a 73 and I replace it this winter I'll let you know. Rod
Fevre, Yes it's a temp gauge from MoonEyes. Rod

Re: Overflow Tank Restoration (chuck d)
You can clean any crud on the outside with a Dremel tool buffing pad and white jeweler's rouge. Both are available at Home Depot. Be careful when using the Dremel buffing wheel and rouge. The "Hot" or "Cold" raised letters on the expansion tank will wear down smooth if too much force is applied. This works of course only for the outside. Do you have any tricks to clean up the inside of the tank?

Re: Overflow Tank Restoration (chuck d)
My current tank is servicable but not real pretty. I tried to bleach it last year and that took a lot of the grud off. I think I will live with it rather than mod the car. Thanks for all the replies. Chuck D

You guys might carefully try a little sodium hydroxide (lye) mixed with water to swish around the inside of the tank. :cheers:

Re: Overflow Tank Restoration (chuck d)
Man, I had the same problem with my '79 and someone on here told me to call the dealer. I did that and 24 hours later I had a new one. Now I have a spare tank. Maybe you could clean the old one with some of that cleaner they advertise called "CLR" think it stands for Calcium, Lime, or Rust. Which are the things that it's supposed to remove. Good luck with whatever way you go.
