To the previous poster - that is very true! Of course it is good to have the part in your glove box, I keep spare bulbs and such in there as well, but to replace this part if it goes out on you in the middle of a trip, would not be ideal to say the least.

The engine bay takes at least 45 minutes to an hour to cool down, and I would not advise trying to replace this part any sooner than that if running hot! The part is right next to the engine and the space is tight.

Plus you need a cool head and the right tools going in. But nevertheless, better to have the part when you need it!
