Links for related partsStock Coolant Reservoir Cap Removal
- Make sure your car is cool, the cooling system is under tremendous pressure when hot and it can cause severe burns if you open the cap while the system is still under pressure. A good way to make sure the car is cool is to squeeze the radiator hoses and make sure they seem soft to the touch.
- In order to remove the stock cap, press down firmly and turn counter clockwise. Sometimes the seals get a little sticky and can hold it in place even if the cap is no longer being held in place by the threads.
- Inspect the reservoir to make sure none of the seals from the stock cap are still in place as they can come off of the old parts relatively easily and will cause coolant leaks if not removed when the new cap goes on.
Installation of New Cap
- Install the new cap by aligning the new cap with the threads, pressing down firmly to compress the spring and then turning clockwise.
