When installing your new Infiniti radiator, take the time to do some extra preventative maintenance that will help you avoid more coolant system failures in the future. Check the radiator cap to see if it can hold its rated pressure. Radiator replacement caps must be rated for the unique pressure levels needed by your Infiniti model's radiator. You can pressure check the radiator cap to see if it can hold its rated pressure for two minutes. To do that, use a pressure tester when the engine is cool. Attach the radiator cap to the tester, then pump it to the limit. If the cap can hold the pressure to its pressure rating for several minutes, then you can keep it. Inspect the hoses and belts for signs of wear and tear, and consider replacing them. Hint: if you need to replace one belt or hose, then just go ahead and replace them all, since they will wear out at the same rate. Check the radiator mounts to see they are corroded or wearing out. Run a check on the thermostat to see if it works correctly with the newly installed radiator. Once the radiator is installed, make sure the entire coolant system is flushed and refilled. Follow the owner's manual on the proper schedule of coolant replacement and flushes to reduce the levels of corrosion in your coolant system. Following these simple maintenance tasks will help you keep your Infiniti radiator for the lifespan of your car.
