Radiator Installation

1. Avoid making any of the radiator mounts solid. Never mount two opposing sides solid as sustained vibration and chassis flex will damage the radiator.

2. Always support the bottom of the radiator from under the tanks only. Do not support the radiator by any part of the core as this can damage the fins or coolant tubes.

3. Any radiator with the cap on the top of the tank is built to be installed with the tanks vertical. Leaning the top of the radiator back tends to reduce low speed air flow, and leaning the top of the radiator forward will increase low speed air flow. Regardless of mounting angle, any time that the filler neck and cap are below the highest point in the system, a surge tank or a means of venting the system at the high point should be installed. WARNING - DO NOT RUIN YOUR NEW RADIATOR BY IMPROPER FILLING !

It is very important that your engine be completely full of water at all times. Aluminum radiators must NOT be subjected to pressure surges that result from air pockets in the engine. When air surrounds a cylinder or an area next to a combustion chamber, the metal becomes extremely hot. Then, when the water circulates and comes in contact with the hot metal, a volume of steam is produced that is larger than the pressure cap can release. The resulting pressure bulges the tubes in the radiator, and greatly reduces the 
air flow and cooling capacity. It may be necessary to raise the front of the car when filling the radiator in order to get all the air out of the system.

CLEANING:

Accumulation of rubber, dirt and speedy dry in the fins of the radiator will drastically reduce it's ability to cool efficiently. The following steps are the best way that we have found to remove this debris:

1. Remove the radiator from the car.

2. Place a piece of plywood or cardboard on the floor that is at least as  large as the radiator.

3. Hold the radiator 8 to 10" above the board parallel to the floor with all the fittings facing up.

4. Drop the radiator so that it lands on the board flat on the tanks only.  Make sure there are no other objects on the floor before dropping.

5. Dump the debris from the board and repeat this procedure until no debris comes out.

6. Wash the fins by laying the radiator flat on the floor and dumping hot soapy water through the fins; then rinse with clean water.

7. Do not use high pressure water or air to clean out the fins as it may bend them over. Bent fins may be individually straightened with a toothpick.
