?? if it is only the pulley /bearing you want to change...THE BOLT THAT IS IN THE CENTER OF THE PULLEY IS LEFT HAND THREAD!!! if it is the whole tensioner you want to change,,,disconnect battery negative,Drain coolant!! remove alternator, of the alternator bolts holds the tensioner on, then there are two more bolts.. heater core coolant goes through this too! spray the plastic elbow that goes from the tensioner to the front of the intake manifold and also the tube that is under the tensioner with good penatrating oil, pry and wiggle very carefully straight out (I broke the plastic elbow on mine) clean holes for coolant and make sure you get new o rings, put engine oil or vaseline in the holes for the o rings.

You really don't need to drain the radiator- only about a quart of liquid will escape. However, be sure the coolant is cool before attempting this! Otherwise have an ambulance standing by.

Pull the tensioner assembly directly towards the radiator, don't twist or rotate it. Even being VERY careful the plastic tubes will probably break. They get brittle from heat. It was a terrible design choice but what are you gonna do they saved maybe $0.50 a car over Aluminum tubes.

They are a dealer item, about $20 for the pair including O-Rings. To be safe, I recommend you replace those plastic tubes when you replace the tensioner.

Also, if the plastic tubes break off inside the housing you'll need to get out the pieces before replacing them. Be careful not to damage the housings.

How do you replace serpentine belt tensioner for 1998 Pontiac firebird V6 3800?

you can not replace the tensioner only. You must replace the entire assembly, which is cast aluminum and has passages for coolant to flow to the heater core. The part is no longer made, and you will need to find a good after-market or search junkyards. Good luck. Took me a while. then: 1. disconnect battery - check water level 2. remove serpentine belt 3. remove alternator 4. Remove coolant connections from tensioner assembly (drain all coolant) and check condition of hoses down to the heater core - these hoses are only custom-order now as well. 5. remove tensioner assembly bolts to remove the assembly from block. 6. replace assembly with new and replace coolant connections. be very careful to seat and seal properly. 7. replace alternator. (I replaced with new and this is suggested unless you have an alternator that is less than 2 years old) 8. replace serpentine belt with new - you will need to visually inspect to make sure it is aligned properly with the pulleys on the tensioner and alternator. 9. refill coolant - use a gravity funnel in the radiator so you can overfill to push air out. 10. reconnect battery 11. turn engine over. 12. bleed coolant of all air with engine running (bleeder valve is near the valve cover to the right) 13. run engine until fans come on (if fans do not come on, there is still air in the coolant and you will overheat) 14. close bleeder when all air is out and fans come on. total time is about 2 hours
