What Does Serpentine Belt Tensioner Do?
Put simply, the function of the tensioner is to retain a certain level of “tension” on the serpentine belt. This predetermined tension held by the tensioner is what keeps the serpentine belt running as designed, pulling all connected pulleys, and causing the car to cruise smoothly.
Is It Safe To Drive With a Bad Belt Tensioner?
No, it is unsafe to drive with a faulty component; let alone, a component that has failed completely. Driving with a bad belt tensioner is very risky and poses greater damage to all the pulleys connected to the serpentine belt and even the engine too.
Bad Serpentine Belt Tensioner Symptoms
When the tensioner is bad, the amount of tension it reserves for the serpentine belt won’t be up to the minimum, or it may exceed the maximum. Hence, it would cause the serpentine belt to wear out faster than it would have done due to age.
Serpentine Belt Tensioner Replacement Cost
You’d be lucky if you found out earlier that the tensioner is going bad. The average belt tensioner replacement cost is $150 – $350 depending on your car model, the level of damage, and the type of tensioner used. The labor cost for belt tensioner replacement is on average $80.

Conclusion – Causes Of White Smoke Coming Out Of The Exhaust
In modern vehicles you rarely see smoke coming out of the exhausts. With the development of technology, we are seeing more efficient cars. So whenever you see white smoke coming out of your exhaust it is not a good sign.
1. You Are Experiencing Condensation
Let’s start with the best-case scenario. You start your car on a cold morning and wispy white smoke from the exhaust pipe puts a scare in you. If the emissions return to normal after a minute of the vehicle warming up, breathe a sigh of relief: You have just been introduced to the smoke vs. steam scenario.
2. You Have an Oil Leak
White smoke exhaust not related to condensation is commonly the result of an oil leak somewhere in the system. Motor oil is a viscous fluid designed to lubricate moving parts like pistons and keep them running smoothly.
3. You Have a Blown Head Gasket
Let’s talk a little more about a blown head gasket because that is a big issue. The head gasket sits on top of the engine block, separating it from the cylinder head. It is the barrier between the combustion chamber, where fuel and air are ignited, and the cylinder, in which pistons pump up and down, powered by the little explosions in the engine.
4. You Have a Coolant Leak
White exhaust smoke from a coolant leak is the easiest kind to diagnose because the antifreeze in coolant has a sweet smell that comes out of the tailpipe when coolant is leaking. A great way to verify that diagnosis is to check the coolant level in the coolant reservoir and observe whether it is low.
7. You Have a Cracked Engine Block
