Bearings in thermostatic fan. Try and run it without the fan on for a minute. Maybe you can even get the fan to squeal by turning it by hand, but you probably won't get it to go fast enough.

I understand the 2006 sonata has a timing chain and not belt but I see a belt of some kind on the engine, what is it?


Hi,
That belt you have seen is a balancer belt, used mainly to eliminate the engines vibration. Actually invented by Mitsubishi, as we all know Hyundai and Mitsubishi have common designs. Thus, all Mitsubishi patented design can have Hyundai's stamp on it!
Hope that helps you out!
Thanks for using FixYa!

Without the belt do all the pulleys turn easy. Power steering, water pump, alternator, and tensioner pulley. There is probably only one way the belt will stay on but make sure you have the smooth side to the smooth pulley and the grooved side to the grooved pulleys. See if any of the pulleys have and wiggle in them.

The belt sound when start the car


this will be your alternator belt, all you need to do is get a tention bar and undo the holding bolt and put tention on the alternator and then tighten up the belt, this will get rid of the noise

Belt goes over power steering pump,under idler on left,over AC compressor,over alternator,over fan (with back of belt ) over crank pulley then over water pump (back of belt) then back to p/s pump. Routing is counterclockwise.

Noise


it is not the steering pump because you are not moving the wheel it is the idler pulley it might need replacing check to see if the belt is in good condition if it is just use belt dressing on the pully to see if the sound goes away if it does then the idler pulley needs replacing

Whistle sound from motor when speed reached above 70


THAT sounds like a bearing in either /Alternator/belt
idler/water pump/or powered steering.
You say when it get to 70 but what is the rpm not speed as all pullys are differant sizes so rotate differant speeds OR check the power steering belt and others for cracks or loose.

I have a high pitched noise which appears to be coming from front right engine compartment (as you are looking at the engine) which sounds kind of like a belt that is squealing. It is intermittent. Just...


Could be several things. WHICH ENGINE?.. 4 cylinder (has three belts, power steering/water pump, alternator & A/C compressor, one tensioner pully A/C compressor), The V6 2.7 (has only one belt, 1 Idler pully and 1 tensioner pully), the V6 3.5 has two belts - A/C/alternator, and power steering - there are two tensioner pullys). Noises can be caused by the belt(s) themselves, pullys, bearings, pully bearings, water pump shaft bearings (or belts/pullys rubbing up against something). Let's not forget that there is also belt(s) behind the Timing Belt cover as well as pullys and bearings associated with the timing system. You could start by removing one accy drive belt at a time (alternator, water pump, compressor, power steering, etc) to see whether or not the noise goes away in each case. If after each case, you discover the noise is still there, it's probably behind the timing belt cover (idler/tensioner pully, water pump shaft bearing, crankshaft bearing, etc.). Good Luck

Surpentine belt.


depends on which v8 you have....the 4.7 the routing is as follows it goes under the waterpump pully over the alternator down and around the power steering pumpto the crank...it goes under the bottom of the crank to the idler pully.the flat side of the belt goes ver the idler then around the automatic tensioner to the ac compressor.
on the 5.2 and 5.9 it routes starting at the idler pully the flat side goes undr the idler the up to the ac compressor around the compressor and down to the power steering pump ... around power stering pump to waterpump where the flat side is against waterpump pully around water pump down and around crank up it automatic tensioner....around tensioner and up and over alternator
