Loud engine

I have a 1996 Jeep Grand Cherokee Laredo. It seems like the engine is real loud. It has the 4.0L in it. Does anyone know what this could be? It's loud anywhere from 25MPH-80MPH.

93BGU... is it engine noise or fan noise? There's a big difference.

A bad fan clutch can be be loud, especially if it's to the point where it's locking and not allowing the fan to freewheel at the normal driving speeds you mention. This can make for quite a roar. Anyway, that's the first and easiest thing to check.

Use the long skinny pedal and you will be okay.

cracked exhaust manifolds are routine on this engine - if this is the problem - take it out & have it welded by somebody that can do stainless steel welding - the advantage of welding VS buying a new on is that the old one is already stress relieved & will not continue cracking - Aluminum Head Welders in Aurbun Washington State are very good at doing these & the GM stainless steel tube manifolds - guy uses a Boeing aerospace material weldiong rod to fix these. ALSO - make sure the gring the flanges FLAT - AHW does this as well as these manifolds are usually warped & possibly twisted.
