Sounds like you have several different problems.

For the heater you may just be low on fluid in the radiator. Your thermostat may also be stuck open.

The loud rumbling could be several things as well. You could have a CV boot, Universal that is going out or gone already, It could also be a brake rotor issue or a wheel bearing.

Does the idle ever operate in a normal range or does it always idle high and wants to take off.

Sounds like a vacuum leak. Check that all your vacuum lines are attached and in good condition.

SOURCE: Very rough idle on 2002 Jeep Grand Cherokee Limited Edition V8

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

My 2001 xterra started making a weird sound between 20 and 35 mph. It sounds like there is a leak in some pressure system.


Common Car Noises and Their Likely Causes Noise More Details Likely Cause Fixing It Clicking noise while turning Starts faint, gradually becomes more noticeable until very loud Failed outer CV joint (constant velocity joint) due to torn boot (most likely) or old age Replace either the whole axle assembly (recommended) or the outer CV joint Water pump noises Difficult to diagnose because of water pump's location Noise usually caused by damage to the bearings in failed water pump Only cure is replacing it. If possible do it at the same time as a timing belt replacement to cut down on labor costs Squeak or squeal from an engine belt Loud, high-pitched squeak or squeal Belts either need adjustment or replacing If belts only squeak when damp, they probably just need adjustment. If they squeak constantly, they probably need to be replaced Exhaust heat shield noises Rattle that you hear when car is idling Damaged heat shield Replace heat shield

Have you checked your oil and fluid levels in the engine and transmisson.
if it's a manual could the clutch be worn out causing the high rpm and thrust bearing noise in the clutch.

1984 reliant. The car runs fine, but it stalls at stops sometimes, and after driving for a couple hours. It runs a really high idle, and when i shut it off in park the engine rumbles and seems to want to...


The stalling and stopping sounds like the FUEL FILTER. My 84 Reliant was doing the same thing to me. And as soon as i replaced that... The car ran perfect.

When in park idle runs high, also sounds loud when shifting


Sounds like you have a major vacuum leak someplace under the hood.Look for any hoses that are broken or came off. You should be able to hear aloud hissing noise if you have a vacuum leak,also could have a intake plenum gasket sucked in or a stuck open EGR valve.

Idle prolem could be a dirty throttle body or sticky air idle control motor.
If the Jeep is a 6 cly. the adjustment for the belt is the power steering pump.
If the Jeep is an 8 cyl. the tensioner is on the pass. side of car.
