Attach the pressure tester to the coolant reservoir or radiator filler neck, and pump it to the specified pressure (typically around 15-20 psi). Watch the pressure gauge for any drop in pressure, which indicates a leak. While the system is pressurized, re-inspect all hoses, connections, and the supercharger housing for leaks. You may also want to use a UV dye test to help locate elusive leaks. Add UV dye to the coolant and run the engine for a short period to circulate the dye. Then, use a UV light to inspect the cooling system. The dye will glow under UV light, making it easier to spot the source of the leak, even if it's small or in a difficult-to-see location. Inspect the supercharger intercooler core if your supercharger system includes one. The intercooler core can develop leaks over time due to corrosion or damage. Look for signs of coolant around the intercooler core and check for any visible damage. If you suspect a leak in the intercooler core, a pressure test specifically for the intercooler may be necessary. Another important step is to check the coolant hoses and connections. Hoses can deteriorate over time due to heat and pressure, leading to leaks. Inspect the hoses for cracks, swelling, or softness. Ensure that the hose clamps are tight and in good condition. Replace any hoses that show signs of damage or wear. Finally, if the leak persists and the source is not immediately apparent, consider a block test. This test checks for exhaust gases in the coolant, which can indicate a head gasket leak or a crack in the engine block. A block test kit typically includes a test fluid that changes color in the presence of exhaust gases. By following these steps, you can systematically diagnose coolant leaks in your supercharger system and identify the specific components that need repair or replacement. Accurate diagnosis is the foundation for effective repair and ensures that you address the underlying issue, preventing future problems.
