Why do the XJs sound loud and like a huge fan is on for like the first couple mins of driving. Then its normal sound? I've noticed they all do it. What causes it?

 

Mechanical fan. They do not all do that though. The fan is engaged all the way. May not be working properly when the speed of fan is not relative to the rpm of engine.

 

Noo its engine noise

 

And yeah they do, every xj I've been in. The motor sounds very loud for the first minute or two of driving. Has something to do with motor warming up, but why

 

If your saying engine noise why not state that in your post?

You say it sounds like a huge fan. Well there is a fan on your jeep that has a clutch and if it was to stick it would run at full RPM no matter the actual RPM. Then when the temp rises it acts correctly.

My jeep does not do what you are talking about. Only time you hear a loud fan sound from mine is if it is reved and release quickly.

Have you been in every XJ?

So fact all Xj's do not do this.
