How do you adjust the serpentine belt tension on your 1992 town car which you think is causing engine to die when you turn on heat and fan?

Serpentine belts have an automatic tensioner, which cannot be adjusted. But your problem sounds like poor alternator performance, have it checked, at your local parts store most do it for free.

If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.

The zd30 has a hydraulic tensioner using an idler pulley to automatically tension the serpentine belt.

if it is a serpentine belt, there is a tension pully that keeps it tight if is a v blet , u generally adjust the tension by moving the alternator

There are a few different ways to adjust the drive belt or V-belt tension in a vehicle. The most popular used nowadays is a serpentine belt that connects to and activates every pulley in the engine. These serpentine belts require no tension adjustment as they incorporate an automatic belt tensioner. This type of tensioner has an internal pre-set spring and applies the correct amount of tension to the belt. Some older vehicles and some imports may use a combination of V-belts and serpentine belts in offset pulleys still controlled by the crankshaft pulley. Most often, there are belt tensioners on these vehicles that allow proper tension to be adjusted.

Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.

If the tensioner isn't working right, you replace it. Tension is determined by the tensioner and is not adjustable.

The alternator is usally on an adjustable slide mounted to the engine. If you adjust the alternator on that slide to take the tension off the belt you should be good to go to put the new belt on. The routing diagram for routing the serpentine belt should be on a placard mounted under the hood on the frame. It should also be in your user's/maintenance manual. Make sure to adjust the alternator properly on its slide mount so that there is sufficient tension in the belt.

No-there is one belt tensioner for the entire engine belt assembly. The timing belt is a serpentine belt and if it is stretched out, it will need to be replaced. There is no way to adjust the timing belt once it is put on the vehicle.

Yes, it is used to adjust the tension on the A/C compressor. Looking into the engine compartment from the passenger side it is to the left of the alternator. To adjust tension you need to loosen the bolt which holds the pulley and then adjust the bolt which is directly above the pulley. Once you have proper tension tighten the pulley bolt.

You don't. The timing belt should have a spring loaded tensioner which pulls on the belt to adjust tension.

If it has a serpentine belt it should have an automatic belt tensioner If it doesn't have a serpentine belt then alternator should be the adjustment/pivot point

Remove belt and tensioner should just be bolted to engine

A serpentine belt on an engine is held in place by a pulley that maintains the proper tension on the belt. This pulley can be pulled up to release the tension on the belt. Do not pull the pulley out, but gently up or you'll risk damaging it.

Water from the road has splashed up into the engine serpentine belt causing belt slippage that makes a squealing noise. The sqealing is one of your engine assessories that use the serpentine belt to drive it.

Tension is accomplished with a belt tensioner, it is probably defective and needs replaced.

The tensioner is the arm on the passenger side of the engine near the front that has a pulley on the end and controls the tension of the serpentine belt. www.trailvoy.com

You don't. The belt tensioner is spring loaded. If you look very very closely at the tensioner, there are wear-indicator marks that can confirm the belt has stretched beyond its useful life. See "Related Questions" below for more

Automatic belt tensioner - if not enough pressure replace tensioner Belt has streched too big, and the Automatic belt tensioner is at its limit. The tentioner is how yo remove the belt, so you should feel its tention with your wrench.

It's common for leaking power steering fluid gets on the serpentine belt - causing slippage and ultimately belt breakage.

1. Remove front engine undercover. 2. Loosen idler pulley (alternator and power steering oil pump belt) lock nut and adjust tension by turning bolt. 3. Same is done for the other idlery pulley (A/C compressor belt).

Put the serpentine belt on to the pulleys of your 1994 Chevy engine. Tighten a serpentine belt with the tensioner pulley.

You dont adjust tension, it has belt tensioner that keeps the belt tight. either your belt or tension is bad, my recommendation is to replace the belt first, if the belt remains tight then you are good, if the belt doesnt then replace the tensioner, but beware, since the belt is a serpentine belt, you may experience problems with other systems such as electrical or cooling since they are tied to the belt drive. just monitor it, anc give the engine a bit of time to adjust to proper function. If you do not you will have failure in other areas. after this is fixed run the engine and monitor cooling system, and check alternator for proper operation, should be charging or output around 13-14v consistently. It all depends on how long the belt has been not tight.

tension pulley is an automatic tensioner that keeps the serpentine belt at the proper tension it is a single pulley that is smooth (no grooves) usually turning clockwise with constant pressure loosens pulley for belt removal use caution pulley is spring loaded
