The zd30 has a hydraulic tensioner using an idler pulley to automatically tension the serpentine belt.
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.
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.
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.
Look in the engine compartment for the "serpentine belt" path & tensioner diagram. Release the belt tension at the tensioner, remove & reverse operation.
There isn't one. The tension for the serpentine belt is an automatically spring loaded tensioner on top of the engine in the front. Place a 3/8 inch ratchet in the square slot of the tensioner arm and pull it back to releive tension on the belt. Then when you put the new belt on pull it back to get it on the pullies then release it to tension the belt.
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
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.
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
My husband and my brother in law need a diagram so they can get my car done. please thank you
If it's like my 93 S10 Blazer, then you use a wrench or 3/8 ratchet fitting to release the tensioner.
Not sure what you mean. If you mean the serpentine accessory belt on the engine you fasten a 3/8 inch ratchet on the tensioner and pull it towards the front to release the tension then you can take it off the pulleys.
First put a floor jack under the engine and raise it just high enough to support the engine, do not raise the car. Secondly, remove the moter mount on the left side of the car. Using a serpentine tool or a small drive breaker bar (not sure on the drive size, I used a serpentine tool that costed around $9 at a discount tool store) move the tension pulley to release tension on the belt. Slide the belt off and out, you may have to wrestle with it a bit to get it thru the small opening where you removed the engine mount. Reverse the steps to install the new 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
That info should be under the hood in the engine compartment, if not get a repair manual or use the internet to see if you can find the diagram that you need.
Some have a indent that fits 3/8 ratchet on base of arm
Put the serpentine belt on to the pulleys of your 1994 Chevy engine. Tighten a serpentine belt with the tensioner pulley.
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
what engine size? 2.0 soc does not have serpentine belts,has 2 serpentine timng belts. need engine size to help more.
There is a tensioner located towards the front of the engine. You'll need a fairly long handle ratchet, a breaker bar preferred. In any event you'll have to determine what on your model has to grab a hold of, release the tension and slide the belt off of which ever pulley is close. Then relaese the tension SLOWLY!!! there is a lot of tension on it and it could snap out of your hand. then reverse the process only retract the tensioner at the end when your ready to put the belt on your last pulley.
4.0 Engine belt routing and tensioner release location
you need a serpentine belt tool, you can get one at auto zone or any part store. the alternator is on a pully system with a belt tensioner. place the tool in the tensioner and pull down, this releases the tension and the belt should come off. besure that you have the proper routing diagram and the correct belt for your engine size and year. Also if you don't want to buy s serpentine belt tool, you can use a 15MM wrench.
it depends on the engine. on a 2.8l, the serpentine belt tensioner is below the power steering pump. pay careful attention to how the belt is routed, especially if there is no belt routing diagram under the hood (should be on the belt guard on top of the engine). release the tension from the tensioner, replace the belt, make sure you have it routed correctly, release the tensioner.
