Radiator Tester

Radiator Power Tester™ Operation

Thank you for purchasing the  Radiator Power Tester™.  The Power Tester™ can be used to test radiator and cooling systems for leaks and also to help in bleeding freshly filled cooling systems.

 Contents:

• Power Tester adapter™ assembly
• 3 rubber spacers
• Instructions

To Test Cooling System for leaks fluids:

CAUTION: Refer to shop manual to determine test pressures.  Excessive pressure could rupture your radiator or other parts of your cooling system.

CAUTION: Test should be performed on a cold cooling system unless shop manual recommends performing test on a system at operating temperature.  

HOT COOLANT CAN CAUSE SEVERE BURNS.  HOT COOLING SYSTEMS ARE TYPICALLY UNDER PRESSURE.  REMOVING THE COOLANT SYSTEM CAP COULD RESULT IN HOT COOLANT SPRAYING ONTO YOU OR YOUR VEHICLE.  WEAR PROTECTIVE CLOTHING AND SAFETY GOGGLES.

1. Remove radiator cap.
2. Determine which of the three rubber spacers allow for a close fit into neck of radiator or expansion tank.  
3. Attach Power Tester ^TMto Power Bleeder ^TM
4. Insert Power Tester ^TMwith appropriate spacer into the neck of the radiator or expansion tank.
5. Tighten knurled knob to provide a tight seal with radiator or expansion tank neck.   DO NOT OVER TIGHTEN.  It is possible to crack plastic necks, especially if the radiator is old.
6. Pull up on Power Tester ^TMto ensure it is snug.
7. Pump to test pressure in 5psi increments listening for leaks at the interface of the radiator neck and the POWER TESTOR^TM.  DO NOT PLACE YOURSELF IN ANY WAY THAT WOULD ALLOW THE POWER TESTOR ^TM TO HIT YOU WERE IT TO BE DISLODGED FROM RADIATOR NECK.  REMEMBER IT IS UNDER PRESSURE.  When at recommended test pressure wait for the amount of time specified in the shop manual while monitoring the gauge on the POWER BLEEDER ^TM.   
8. If system leaks down and the POWER TESTER^TM is not leaking around the neck of the radiator inspect other parts of the cooling system to see if you can see or hear a leak.
9. If system leaks down and you can not see or hear a leak this maybe an indication of a head gasket problem.
10. When testing is complete remove pressure by slowly unscrewing the pump from the POWER BLEEDER^TM tank.  If fluid level in radiator is high you may have a small amount of fluid back flow into the POWER BLEEDER ^TM.  Insure you clean the POWER BLEEDER ^TMtank and tubing using denatured alcohol prior to further use.
11. Properly dispose of/ recycle removed fluid.

To Vacuum Bleed Radiator:

CAUTION: Refer to shop manual to determine vacuum level.  

CAUTION: Bleeding should be performed on a cold cooling system unless shop manual recommends performing test on a system at operating temperature.  

HOT COOLANT CAN CAUSE SEVERE BURNS.  HOT COOLING SYSTEMS ARE TYPICALLY UNDER PRESSURE.  REMOVING THE COOLANT SYSTEM CAP COULD RESULT IN HOT COOLANT SPRAYING ONTO YOU OR YOUR VEHICLE.  WEAR PROTECTIVE CLOTHING AND SAFETY GOGGLES.

1. Remove radiator or expansion tank cap.
2. Determine which of the three rubber spacers allow for a close fit into neck of radiator or expansion tank. 
3. Attach Power Tester ^TMto Power Extractor ^TM or other vacuum pump (note user will need to provide a method to connect Power Tester to a user supplied vacuum pump) or have Motive Products p/n 0420 for use with the Power Extractor
4. Insert Power Tester^TM  with appropriate spacer into the neck of the radiator or expansion tank.
5. Tighten knurled knob to provide a tight seal with radiator or expansion tank neck.   DO NOT OVER TIGHTEN.  It is possible to crack plastic necks, especially if the radiator is old.
6. Apply vacuum to cooling system as per shop manual (do not exceed 15 inches of vacuum for the Motive Products Power Extractor^TM).
7. To release vacuum slowly loosen knurled knob.

To Use as a Brake Bleeder Adapter:

The Power Tester ^TM  can be used as an adapter for the Power Bleeder ^TM  to bleed brakes.  This use is only recommended for cars that cannot use any adapters manufactured by Motive Products or for some boat trailers.    Please see the Motive Products website for a list of caps that can be used on most cars, trucks and trailers. www.motiveproducts.com

WEAR PROTECTIVE CLOTHING AND SAFETY GOGGLES.

1. Remove brake fluid reservoir cap.
2. Determine which of the three rubber spacers allow for a close fit into neck of brake fluid reservoir.
3. Attach Power Tester ^TMto Power Bleeder ^TM
4. Insert Power Tester^TM with appropriate spacer into the neck of the brake fluid reservoir
5. Tighten knurled knob to provide a tight seal with radiator or expansion tank neck.   Pump to bleeding pressure in 5psi increments listening for leaks at the interface of the reservoir  neck and the POWER TESTOR^TM.  DO NOT PLACE YOURSELF IN ANY WAY THAT WOULD ALLOW THE POWER TESTOR ^TM TO HIT YOU WERE IT TO BE DISLODGED FROM RESERVOIR NECK.  REMEMBER IT IS UNDER PRESSURE.  Follow directions on Power Bleeder ^TM  Tank to bleed brakes.
6. DO NOT REMOVE POWER TESTOR^TM FROM RESERVOIR NECK UNLESS POWER BLEEDER^TM  HAS BEEN DEPRESSURIZED.
