Question about 1995 Jaguar XJ6

1 Answer

Noisy air pump

The air pump on my X300 has begun making a loud whining
sound on start up which continues until warm up. Disconnecting the electrical connection stops the noise. If I permanently disconnect the electrical connection to the unit will this
have any serious adverse effect on the car other than a
negative effect on the car's emissions which is what I
believe the pump is there to prevent?
Alternatively, other than replacing it, can it be 'serviced'
in some way?
Thanks in advance.

Whining noise on Volvo 240 when in neural and park


A common cause of a whining or buzzing type noise when not in gear (neutral and park) is a WORN PUMP in the transmission. How many miles are on the car??

A noisy pump is just noisy and won't cause a breakdown until it becomes MUCH louder. If the noise is not that loud at this point, just keep driving it for now, and chalk it up to normal wear & tear. But DOOO make sure your transmission fluid is topped off. The amount of fluid between the LOW and FULL marks is about one pint. DON'T overfill OR allow it to get below the LOW mark. Transmissions are VERY fluid-level-sensitive.

Power steering whining, sqreeching


hi Eva.
As you turn your steering wheel it is this fluid pressure that aids in turning the wheels of your car. ... If the pump impeller is trying to move power steering fluid and starts catching air bubbles it can cause whining noises and vibrations to occur.
Maybe you've heard it at a stop light. Maybe you've heard it as you pass a car on the freeway. Or maybe you've heard it in the parking lot at work when someone is leaving. The unmistakable whine of a power steering pump can make even the most confident mechanic wonder when that car will breakdown.
Power steering pump noise is a unique noise that your car may make and once you've heard it you always know what it is. The noise is a mix of a whirring and a whining and will always vary with the speed of your engine whether your car is driving or in park. This whining noise can be subtle or extremely loud and may be worse in colder weather, or right when you first start your car.
Power steering pumps are most often vain style centrifugal pumps that are tasked with pressurizing the power steering fluid and pushing it down to your power steering gear or rack. As you turn your steering wheel it is this fluid pressure that aids in turning the wheels of your car.
There are a few reasons why you are hearing power steering pump noise from your car. First, it may simply be due to the design of the pump. Sometimes, noisy power steering pumps can continue to work flawlessly for years after they start making noise. This may simply be due to the manufacture's design or a tight tolerance in that particular pump. In this case, you would hear the noise but not see any other adverse effect like a loss in power steering, leaking fluid or a wobbly pulley. In this case, you may be able to help reduce your power steering pump noise by choosing a different type of power steering fluid, like a synthetic fluid.
Your power steering pump may also be making noises due to air trapped in the system. If the pump impeller is trying to move power steering fluid and starts catching air bubbles it can cause whining noises and vibrations to occur. Even tiny air bubbles you cannot see that are trapping in the power steering fluid may be causing the whining you are hearing. In this case, the best thing to do is flush your power steering system to try and remove the air from the system. Having air trapped in your power steering system can be difficult to diagnose so you may need to simply try a power steering flush to see if it solves your problem.
Power Steering pump noise may also be due to a failing power steering pump. As the bearings on the impeller go bad it will start to make noise as the pump is turning. If you have a bad power steering pump you usually will also experience leaks from around the pulley, a wobbly pulley, or difficulty turning the steering wheel when you are stopped. If you have multiple of these symptoms together, it is probably time to replace your power steering pump.
Lastly, and most usually, a whining power steering pump is an indication of a low fluid level. Your power steering fluid is probably something you have rarely if ever checked, so it often comes as a surprise if the level is low. Your power steering fluid reservoir is also relatively small so even a slow leak will cause a low fluid level relatively quickly. To confirm this is your problem it is as simple as checking your power steering fluid level. Some power steering reservoirs are clear so you can see through them to check how full they are. You may have to wipe away some dirt and grime to find the "full" line, but it should be easy to check. If you have an opaque power steering fluid reservoir there should be a small dipstick under the cap that will help you measure the fluid level. If it is low, then you have a leak somewhere and topping off the fluid should quite down your power steering pump.
If you discover a power steering leak, rather than simply continuing to add fluid every time it gets low, you should fix the problem permanently so you don't have to continue to check your power steering fluid level. Replacing lines or seals can be a surprisingly difficult task due to the location of your power steering pump and steering gear or rack. The easiest way to seal your leak is to do it from the inside out!

I can hear the fuel pump cut on and then cut off. and off but it seems very noisy. Is that an indication that it is bad? The engine tries to start


If fuel pump is whining excessively loud then yes it is a definite sign it is going out. Don't have enough information to advise you whether or not this will fix your current condition but a noisy fuel pump is a failing fuel pump.

Power steering pump is whining, I replaced it and the new one whines just as loud. what could be wrong


make sure your using power steering fluid recommended for the vehicle. If automatic transmission fluid it aerates causing bubbles. It's very similar to the effect of shaking a bottle of liquid detergent vigorously when half full. Having that much air in the system can cause it to whine very loudly and reduce the life of the pump.
