wamcneil Posted January 21, 2021 Share Posted January 21, 2021 Hi all, Couple-years ago my coolant reservoir was cracked and I couldn't find a reasonably-priced replacement, so I fixed it with epoxy. While I wasn't super-excited about trying to fix the poly tank with epoxy it has held up so far (not being pressurized...). Anyway, in the course of fixing my AH filler neck and searching for a new pressurized coolant tank, I came across this 6-qt reservoir: 6 Quart Natural Multi Purpose Tank with Mounting Tabs - 8.62" L x 4.17" W x 15.29" Hgt. (2.25" Neck) | U.S. Plastic Corp. That really looks like the original tank to me! Minus the AH logo... Might need to transfer the overflow tube. Maybe this is one for the parts list??? Cheers, Walter 1 Link to comment Share on other sites More sharing options...
vito.a Posted January 22, 2021 Share Posted January 22, 2021 Great find! Let us know if it fits? 1 Link to comment Share on other sites More sharing options...
wamcneil Posted June 23, 2023 Author Share Posted June 23, 2023 (edited) Sorry I never updated on this! I should have measured better... It is exactly the same bottle, but too tall. So, don't order the 6-qt like I recommended... 5-qt should be an exact replacement. 5 Quart Natural Multi Purpose Tank with Mounting Tabs - 8.62" L x 4.17" W x 12.9" Hgt. (2.25" Neck) | U.S. Plastic Corp. (usplastic.com) The tank is cheap... but shipping is horrendous. Edited June 23, 2023 by wamcneil 1 Link to comment Share on other sites More sharing options...
wamcneil Posted June 14 Author Share Posted June 14 Well, it looks like this made its way into the parts list. But it's the original link I posted, which is not correct. Please update the parts list to link to the 5-quart version of the tank in the previous post. The 5-quart is identical to the original aqua hot tank except it doesn't have the high/low markings and you'll need to drill your own hole to swap over the dip tube. They also have smaller versions with the same mounting flange. On my system, the liquid height varies 3-1/2" between cold and hot, so a 3-quart reservoir should really be plenty big. 1 Link to comment Share on other sites More sharing options...

radioman Posted June 16 Share Posted June 16 I wish they showed the size and location of the ports. Link to comment Share on other sites More sharing options...
wamcneil Posted June 16 Author Share Posted June 16 There are no ports. Just two flat areas on either side of the cap. You would need duplicate your original reservoir and drill a hole in one of the flats and transfer over your original dip tube and elbow. Link to comment Share on other sites More sharing options...
