![]() ![]() (It is good practice to bring the old radiator cap with you to be sure you are purchasing the correct part.= 0) $("#trkFooterDiv"). Made from high-quality materials to ensure life-long durability. This tester ensures an automotive cooling system is operating at the correct pressure for optimal performance. Make sure you know the year, make, model, and engine size before you head to the parts store. The MotoRad MT-300 cooling system pressure tester is the professionals’ choice when it comes to testing vehicle cooling systems and coolant caps. (7) Install the old cap if it is still good, or if necessary buy a new radiator cap. It may lose some pressure, but should not rapidly lose a good amount. (6) Pump the pressure tester handle until the pressure builds to the manufacturer’s specification. (5) Attach the adapter with the installed cap onto the pressure tester. (4) Attach the radiator cap to the pressure tester adapter. This can occur due to corrosion, physical damage, or a faulty weld. Coolant may come out when you remove the radiator cap, so it’s best to be prepared for this possibility. Radiator Leaks: One of the most common failure points is a leak in the radiator itself. (3) Place a catch pan under the radiator. Despite the cooler hose temperature, however, extreme care should be paid as there may still be hot pressurized coolant in the system. If the radiator hose is cool to the touch the motor has cooled down and you can remove the radiator cap. Do not attempt to remove the radiator cap while the system is hot, or injury may occur. Keep in mind that if the system is hot, extreme pressure and heat are at play. For use in testing radiators For use in testing radiator caps Confirms radiator leaks Confirms cooling system leaks Test radiator caps for proper operation. Carefully touch a radiator hose to determine its temperature. (1) Make sure the cooling system is not hot. In order to pressure test the cooling systems of specific vehicle makes and models, appropriate manufacturer adapters are required. We’ve mounted our spare set and used a piece of pipe (roll cage pipe in this case) to close the loop. Applications: Chrysler, Ford, GM, Mitsubishi, Nissan. We’re using spare hoses because they might get damaged in the process. FJ4368 Radiator / Cooling System and Radiator Cap Pressure Test Kit SKU: FJ43658 Description. The standard pressure for most systems is between 13 and 16 psi. The gauge on the pressure tester will measure the pressure. Apply pressure on the cooling system up to the pound per square inch (psi) mentioned on the cap. Remove the old hoses from the radiator and mount the spare set. Step 6: Put pressure within the psi limit. Choose the correct radiator cap connector (43302-5A or 43302-5B) and correct steel radiator cap (43300-2, 43300-3, or 43300-4) for the correct vehicle being tested from the test kit. The pressure of a cooling system is controlled by the radiator cap which generally holds the pressure of the system between 6-16 PSI and keeps the temperature in check.įJC Radiator and Radiator Cap Test Kits come with everything you will need to pressure test most vehicles (including the caps). Step 1 Mount Spare Hoses and Close the Loop. TO TEST FOR LEAKS IN ORIGINAL RADIATOR CAP: 1. Normal operating temperature of a cooling system is around 220 degrees Fahrenheit, which is slightly higher than the boiling point of water. If the pressure releases the pressure before reaching the correct pressure, or the cap. As the coolant in your cooling system increases in temperature, the pressure in the system also increases. Pump the pressure tester to the pressure stamped on the radiator cap. ![]()
