Champion Radiators: How to install an Overflow Tank in a vehicle

Upgrading your cooling system? Then you should also upgrade your recovery tank to a Champion Cooling Stainless Steel recovery tank to give your car the performance and head-turning looks it deserves.

Keep in mind, the shortest tube on the bottom of the tank is the shortest one inside the tank, and should be connected to the radiator. The longest tube on the bottom is also the longest tube inside, and allows the tank to fill up before any overflow is dispensed.

Thanks for the illustration showing where the two hoses hook to the recovery tank. Embarrassing but I think that's been my coolant problem for years🥴

Does the size of the coolant tank matter as long as it’s not ridiculously small

[deankay]

If you have air in the radiator, you may have a leak. But yes, it should be full to start with and it recovers the hot expanding coolant as the engine reaches correct operating temperature and the pressure exceeds the caps rating. If the cold radiator is low after re-filling several times, have the pressure cap tested, the caps vacuum relief valve cleaned and inspected, then pressurize the coolant system. Other, very nice product. Retired ASE Master Tech.

Nice video. Does the cap of the recovery tank have to be at any certain height in relation to the cap on the radiator? Higher, same height or lower? Thanks! Which item # or capacity for a SBC Chevrolet 350?

[leliamartin]

Should I add any coolant to the overflow tank after installing it for the first time?

[NoblesTx]

Short sweet and to the point. This is what I was looking for, thank you.

[CrazyMaggot]

Where does the tank bolt on to? is there fittings on the actual radiator for it to be threaded in?

[kevinhumphrey]

Why are the line so small going in and out of the tank I finally tossed mine in the trash because I couldn't find 1/8 to fit it and the radiator

[yoyyoy]

what's the different between overflow tank, breather tank and reservoir?

[foxmob]

What hose can i use for this my stock one or would i need a new one size?

[lenoechsner]

Which vent/tube does the relief hose get attached to? Short or longer?

[ParisTheMotorhead]

This is where I'm a bit confused too. The nipple that doesn't go to the radiator cap can I run a hose from the overflow tank to a coolant reservoir I've already installed? I have a 72 Monte Carlo. 350 engine.

[henrydixon]

do the recovery line on the take get connected to anything?

[mikeashford]

Alright I purchased a CC1164 Radiator and the recovery tank but there are no brackets for bolting the recovery tank to the Radiator anywhere is there something missing or do I need to order something else to finish off the head-turning look . How do I get a sales men to help me finish this system correctly

[samdeo]

I have one of these tanks, works well but I always wondered how high the tank should be mounted compared to the radiator? I'm running this in a 58 Dodge Coronet which uses the stock radiator. The recovery tank sits about 4" lower then the top of the radiator, is that ok?

[Juan-dsde]

Where exactly was the overflow tank mounted on? I bought a radiator with electric fans.

[trent]

Bought champion radiator, it started leaking from where find go into tank after 2 months....got replacement and same thing happened.

[patrolmanmalik]

How can I install they have a 2 nipple which one is going to radiator cap and the other one nipple is where ? Thanks please reply ASAP before I buy it.

How to install an Overflow Tank, , ,,Did I miss it?

[ftintheflames]

Lol there shouldnt be air in the system after the inital purge after filling the system up after service or repair. The purpose of the cap opening and the overflow is exactly what its called. Overflow. Coolant expands while gaining temperature. Taking up more space. The system does not have anywhere for the coolant to go after its taking up more space. The cap opens and stays open at spec pressure and temp allowing the expanded fluid to escape the system into the overflow bottle. The inlet to the bottle is on the bottom of the tank. In doing so as the system cools while the engine has been turned off the fluid in the radiator and block cools down and begins to contract. This creates a vacuum on the overflow bottle and the coolant in the bottle will then be sucked back into the radiator. This keeps it leveled off and the radiator empty of air. The only time you will see air in the system is if it wasnt purged correctly or if theres a leak where air will get sucked in after coolant is lost somewhere in the system. Describing it the way the video does is like the way gimmick companies describe intake kits and why they would benefit power gains. Saying more air equals more power. When really more air equals more fuel that can be introduced to the mixture that couldnt be before the extra air was added. More fuel per combustion cylce equals more power. This all of course is only valid if your using the correct grade of gas. Since most people dont know it and just think everything is okay to run on regular unleaded. They dont realize they put it in something that at minimum requires mid grade or higher. But then they wonder why they consistantly get shitty milage and power. To low of octane and you get more counts of knock. More counts of knock and the computer retards timing to lower the knock count. Retarding timing is a power loss and major milage drop. Using a higher octane will lower the knock counts and will allow the pcn to advance timing and allow more complete atomization and combustion(fuller burn of the drop of fuel being injected) to where you end up getting more power out of using less fuel allowing the pcm to run the injector for less time per cycle until it needs it when you open up the throttle. In which the open intake will give a better throttle response and milage over stock. (If your using the correct fuel) more air doesnt equal more power. It equals more usable fuel burn. Cant add more fuel without adding air. Cant achieve more power without advancing timing and adding that little bit of extra fuel with the extra air.
