Question about 2003 Hyundai Santa Fe

1 Answer

My engine became very loud after a new ac compressor and serpentine pulley was put in. It does it only when driving. When the car is in idle there is no noise. It's sluggish and hard to steer

Not positive without more info, but since you mentioned hard to steer, check tension on all of your drive belts. Hyundai is bad about not designing enough contact between drive belts and their corresponding pulleys. Consequently, they will squeak, squall, chirp, and cause erratic/hard steering. Many new belts nowadays will "wear-in" initially and need to be re-tensioned soon after installation, or it's possible that the mechanic just did not get it/them tight enough.

Does it act the same way if the A/C is off? It is possible that the the A/C pump was bad or has been over charged (which can cause it to lock up). If its not better with the a/c off, it could be the clutch on the a/c pump. See if the A/C belt can be removed and still keep the water pump rotating (don't want to run without the water pump turning - it will overheat!. If so, remove it and see if it changes anything.

Hope this helps.

SOURCE: Hello, I purchased a 2003 Hyundai XG350 last

See if it goes away when you turn the A/C off. The a/c comes on when you sre in the defrost so yo don't hit the windshield with hot air. The screaching is more than likely the A/C clutch trying to engage, that why it was overlooked or ignored by the mechanic. It is a common thing. The battery should be allowed to recoup from the starting of the car which a few minutes of running woll help so the a/c clutch gets full battery voltage to function.. Turning on the defrost and /or the A/c after about 3 minutes of warm up. Open your hood and have someone turn the a/c on and off, you can hear and sctually see the a/c clutch doing its irritating thing.But keep your fingers out off the engine and don't lean over it with loose clothing. Good Luck, Ned

SOURCE: My daughters car is hard to steer and makes a loud

Those cars have manual belt tensioners and sounds like it needs to be adjusted because it has stretched the belt.

SOURCE: Have a 2001 Hyundai Santa Fe v6 2.7liter. Ac compressor locked up and broke the serpentine belt.

Try A/C compressor clutch bypass. I believe some that I looked up were about $40-60 made by Dohrman. Your car is Foreign so it may be much higher. They are available through autoparts stores.

I searched and Advance Autoparts had some for different cars and a 15% Online discount. But you need to look at what has to come off to install it.

Also the part may show 6G where G is the number of grooves on the belt. This is crucial.

Depending on the configuration of the pulleys, all you may need to do is use a smaller belt and leave the old stuff in place. If A/C was an option for your car, try a belt from a VW without A./C.

You just need to remember that the Tensioner pulley has to work or the belt will slip off. That gives you a little leeway. Check for a different Tensioner pulley for the Non-A/C equipped VW which may be needed for this change.

SOURCE: my ac is only cold when I am driving, my heat is only hot when I am driving, not getting cold air or hot air in idle position?

So many mechanics, so little consensus. Sounds pretty common.
I can't say as to why hot and cold only when moving, but it sounds like a weak performing system.
As for the squealing, I would suggest removing one belt at a time, and see if one eliminates the squeal. That would be the problem belt or pulley or component. Also, if you have any idler pulleys (a stand-alone pulley) on the belt system, be sure and check them as well. Spin them without the belt on, and see if they make any noise.
It would seem you need a mechanic who is willing to spend some time with you on this to find the problem. When you find a good one, you will know it by his output, and make yourself a regular customer. Good luck.

I have a 2007 Chevy Impala which had a tension pulley that melted and snapped the serpentine belt. When I turn my AC it makes a loud squeal and also has the ability to power my car off after trying to...

I'm going to bet the a/c compressor locked up which put extra load on the tensioner which melted the pulley which snapped the belt. With the engine off the center part of the pulley should turn by hand as well as the part with the ribs that the belt rides in. If either one of those, I suspect the center part, is not turning than the compressor needs to be replaced.

90 Dodge Dynasty 3.3 squealing serpentine belt

Sometimes when you have things changed out on an older car like that it will tend to show the next problem. Take the serpentine belt off and check all of the other pulleys. I am willing to bet that there is another one that is bad. Water pump, ac compressor etc.... The belt is trying to bind up that's why when the rpms get close to idle the car wants to stall

On a 2001 saab 93 turbo can can you bypass the ac compressor or is there a bypass pulley

You can bypass both the AC compressor and the middle serpentine idler pulley with a 6PK1790. The middle pulley is bypassed by running the belt straight line from the upper rear serpentine idler straight to the power steering pulley, then over the water pump (the smooth pulley powered by the back side of the belt) and down to the engine drive pulley (harmonic balancer), bypassing the AC compressor) This works fine. On 9.5 models, the same basic idea, but a slightly different sized belt.

Serpentine belt slips off idler pulley

The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.
