How easy is it to change the serpentine belt?

[wiswind]

some of those bolts can be super hard to break free....
You might try soaking the bolt that you want to remove with PBlaster.....it seems to work as well as anything....and you can buy it at most auto part stores.

I remember it was hard to get that bolt to break free. I used a nice heavy hammer on my wrench. I think the factory uses thread locking compound on the bolt.

Make sure you're turning the right direction (ccw when looking at the head of the bolt).

BTW, in my case, this repair was required because the tensioner was 'frozen' which allowed the serpentine to slip. The tensioner bearing (actually a bushing) was worn out and the tensioner arm was cocked out of alignment.

Thank you so much to everyone quote and help me with my trouble. I all ready change de tensioner and all work perfect. This 18mm bolt is the more hard bolt I never ever take . Again.. Thank you and now i'm ready for the next question: When my van ride for a capo miles.. the oil light come on and flashing anytime i'm stop. Some body talk me i need to remplace the head gasket.. is that correct? Also the color of the smoke is white when the van starter. Thank you

Lower intake manifold gaskets and/or the front cover (timing cover) gaskets are the common leakers that get coolant into the oil.

The front cover gasket would not give you any coolant into the cylinders.
The lower intake manifold gaskets can leak coolant into the intake.....which is then drawn into the cylinders.........fooling people into thinking that it is the head gasket.

Most ANY motor will give you the white smoke when you first start it up in cold weather.
Are you needing to add coolant to the vehicle?

In any case.....if the oil pressure light is coming on.....you need to get that addressed ASAP as lack of oil......or coolant into the oil can cause MAJOR engine failure $$$$

If it is only at idle.....you may still be OK......but still need to look into it.
A shop can do a oil pressure testing for you.....and advise you from there.
If it is a defective switch....then you would want to get it replaced.
In any case......a pressure gauge connected to the oil pressure switch location is in order.......to see if the oil pressure is within specifications.

The oil pressure switch is located in a hard to get to location......under the power steering pump bracket.....

Here is a link to a picture from my '96 3.8L that shows the oil pressure switch......the picture was taken with the alternator, power steering pump and bracket removed.
