What causes an intake manifold to crack 2003 Jeep Grand Cherokee?
They almost always crack on the very front hold down ear. It is a poor design by Chrysler, and used ones are hard to come by. When torquing down the intake mounting bolts tighten them even, and a little at a time. 20ft lb is plenty on the front bolt. This is a problem in the 99-04 Grand Cherokee, and others using 4.0 engine.
Is it harmful to drive a jeep grand Cherokee with a vacuum leak?
prolonged use could clog up your catalytic converter with unburned fuel, but if the engine will stay running with the vacuum leak you shouldbe able to limp it home, be sure to get it fixed soon, the poor runing, the shaking, stalling, and sputtering will eventually lead to bigger issues.
What is the average expected mileage for a 2000 Jeep Grand Cherokee?
48,000-56,000. >>>Depends on the year you are asking! I would try Kelly Blue Book or some other service on the internet. Improvement to answer...hopefully I assume you mean MPG, not mileage. I get about 22MPG on mine and it has just under 100,000 miles. It is a Grand Cherokee Laredo. Well i have a 02 4.7l v8 and i get 15.8 mpg..and i light foot it! You will never get 22mpg not matter the v6 or v8! I do not live in the city its country which is mostly like highway! I have tried e3 spark plugs and they are not worth a dime. My jeep has 141k miles with stock everything never one problem! Just always use full synthetic oil. And change tranny oil every now and then.
Why doesn't your ac blow in your 2002 Jeep Cherokee?
The AC in all years of Jeep Cherokees blows......it also sucks. Go figure... It takes a really good automotive engineer to create a system that is so subject to failure and so difficult to repair. Good luck to you !! answer: I have to assume you have a Grand Cherokee. If the blower motor is not coming on the most common failure is a poor connection at the blower resistor module (located under the dash on the right side close to the firewall) this usually causes the wiring terminals to overheat and melt damaging the wire terminals and blower resistor module. this condition is most common on models with dual zone a/c system. you will need a new blower resistor module and a wiring connector repair package (available at dealer)
