Cleaning the cooling reservoir tank

Any good advice for clearing out all that brown junk from the cooling tank?
I finally am redoing the entire system and want to be sure I get as much as possible
out of circulating in the system.

Additionally, is there any method for restoring the color of the tank itself?

1. This:, especially #7
https://www.impalassforum.com/vBullet...ng-system.html

I used Magic Purple - shake - flush - repeat - final flush distilled water - drain on end

2. Only Paint. Or wait for Year One to make one. Or maybe still some NOS.

I can't help with the color of the tank itself. I have seen a few painted body color at shows, and it looked great. For that you will want to prep the surface with something like ScotchBrite, and clean with lacquer thinner.

What I did with one of my tanks was pour a few ounces of your favorite degreaser (Simple Green, Super Purple...etc) in the tank with a handful or more of ice cubes and shake the hell outa the tank. Rinse and repeat as needed.

It worked quite well for me.

I've just removed the reservoir and put it in a cleaning tank to flush it out. Still does not get the whole thing Looking clean but gets most of the crud out. I've read some have used Ice (as mentioned) or even BB's to help agitate the inside of the tank to loosen the crud and then flush it out.


Along the same lines of the Ice or BB's, I found this video that he uses Rice along with some chemicals to really clean up the tank.




It actually does a really good job. He then also uses some Hair Care products to bleach the tank and its amazing how well it comes out and removes the discoloration. Just be sure to flush the tank extremely well if you use chemicals and protect your eyes/skin. The only difference between his tank and ours....we have a lot more hidden passages inside our LT1 Reservoir. So results could vary on our tank versus his open tank.


If this does not work to your satisfaction then your only option may be to purchase a New Reservoir.

Thanks for the vid. Quite impressive recovery. I'd be VERY leary of using such harsh collection of caustic chemicals on anything other than a simple blow-molded tank v. one which has a (sometimes commonly failing) main seam as ours do.

I bought a new either an NOS or repro tank for my son's '88 Monte for less than what that guy had in buying chemicals.

Thanks for all the info. I was a bit concerned about dealing with all the hidden passages in that sucker. The suggestions here worked nicely.

As far as recoloring the tank, I completely forgot that there is a product to re whiten old computer cases. I will look into what is involved and see if it is usable on the tank itself.

I love my car, but dang, several bad mechanics and having it stolen has created quite a mess for ME to fix and sort out.

Heater REAL hot

I can see 165 at the outlet when it 60 outside and at 30 out I see 130......This is what I did,I back flushed the unit, then reversed the hoses and added a WIX cooling system filter. The flow is backwards and cleans out any remaining crap in there...Oldhead

Scuff, clean, shoot with Krylon Fusion satin black. Looks factory, same as the reservoirs on the Vettes.

Old cars, just like classic rock... 60s, 70s, 80s, and 90s!

They have new OEM tanks all over the internet. They are under 100 bucks. Thinking about getting one because one of the nipples on mine may have a crack in it now!

Here is a link: coolant overflow tank roadmaster caprice impala | eBay

94 RMSB 170K Sat 5 years, ran for 1 of those then remained untouched for 4. Sat because it was slapped by a deer and the owners didnt want to fix it for whatever reason.
Mods, all the free good ones.
Future? Probably pull engine, reseal it, and run it a lot more. Looking to get 250k out of it. PRAYING for 300k.

Careful with NEW Tanks being offered. Getting back to the whole New GM Parts issues we've seen lately on other parts. But I seem to remember a few posts from Members that said they got a new Tank and found it was leaking at the Seam. Maybe just a bad run of parts but my original tank still does not leak and the Crud is minimal if you keep your system clean and flush the tank real well.

The only thing I don't like about painting the tank is that you can't quickly see the coolant level. I guess it's not that difficult to just remove the cap for a quick check in the tank for level. So maybe not such a big deal but I also like how the tank sort of breaks up the overall Black Engine Bay.
