Overall Function Check: Notes

WARNING: This page is about a different car, the 2013 Nissan Xterra. However, it is still accessible from the selected car via links, so may be relevant.

Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be confirmed.

WARNING: Never remove the radiator cap and/or reservoir tank cap when the engine is hot. Serious burns could be caused by high pressure fluid escaping from the radiator and/or reservoir tank.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up pressure to escape. Then turn the cap all the way off.
