Ahhh. Good point.

Default Undrehood Heat

I cut the weatherstripping from the back of the hood/cowl. Just the area behind the battery area. This leaves a nice gap for the heat to escape. So far I have not had a problem with the rain running in.

good idea, why didn't I think of that? I was contemplating puttin' more holes in my Jeep.....

and your air box is in the front, so water won't get that far ahead......

I **Believe** it must be a 195 or maybe 190. I've added a scangauge to my jeep and I'm consistantly getting temps (once warmed up) between 197-203 degrees while crusin' and a *high* of 213 degrees while stuck in stop-n-go traffic for 1.5 hours

What about ceramic coating the exhaust manifolds? Anyone tried that?

thats not a heat shield it is a fire blanket, that has some noise deadening feature

the plastic clips that hold it up melt and the fibreglass cloth shield falls over the engine and smothers the fire.

i tossed mine
became soaked and full of mud and started to rest on the engine.

Wouldn't the heat shield act as an insulator in the summer making the engine compartment even warmer?:thinking:

The heat shield did come on the X, I have an 07 with it, while my friend's 08 X model doesn't. It was a line change on the vehicle if I understood correctly (i.e. some 07 models were made with, then design change during production / cost cutting, etc., they stopped putting them in). A lot of people have just been pulling them out, I will probably will when I get around to it.
