Recovery System Info: Keeping the system full reduces aeration and maintains pressure. As the temperature increases the water expands and pressure builds. If the system is completely full the expansion pressure will exceed the cap pressure and over flow into the recovery tank. If your pressure cap is properly located, on the low pressure side of the system, air is pushed out first. When the system cools a vacuum is created. When your radiator cap is equipped with a valve that opens under negative pressure it will draw coolant back into the system. The tube that extends to the bottom of the recovery tank transfers the coolant back to the radiator. Mount the tank as close as possible to the pressure cap. The line should be short and level, reducing restriction and the effect of gravity. If the recovery tank is kept 1/3 full (with the engine cold) every heat cycle will automatically purge more air out of the system. The opposite is true without a recovery system or with an improper pressure cap location. With every heat cycle water will be pushed out, leaving more air space. This air space can be compressed lowering the boiling point.
This part number features:
- Made from 2"x3"x.125" rectangle aluminum tube.
- 28 ounce capacity.
- O-ring sealed #12AN cap for a filling provision.
- Supplied with a stainless fitting that reaches to the bottom of the tank to provide the "recovery" action.
- The remaining 1/8 NPT port on the top is for a vent to be run to the rear of the vehicle.
- The bottom has a 1/8 NPT port which is factory sealed but can be used if so desired.
- Show quality finish.
- Two crosstubes are welded into the tank for mounting on a 5" vertical center to center. There is a 1/4 through hole and a 5/16-18 thread in these tubes.
