Over the past couple of days right after I start my truck I get a real quick but loud screeching sound. it almost sound like it is running with no oil for that split second. Today as soon as I turned the key to start it for the first time it did it. but every other start today was fine nor noise at all. just wondering if someone could help me out. Thanks



Oh yeah my truck is a 99, 3.0 Auto 2WD

 

Check your belt. Low oil would cause a tapping sound from the lifters.

 

Sounds like a belt squeal, it does that when you start it because its cold. It could be getting worn out though.

 

or it does it when the belt is really wet

 

Or loose.

 

I plan on changing the belt on Monday. so hopefully that will solve the problem. Thanks guys.

 

i can almost guarantee it is the belt tensioner. when you start it, its either really tight/loose and it makes that squeak, also wears the belt out faster. look into it.

good luck.

Sounds like the belt tensioner to me, but also check your oil level and viscosity because it should make lifter noise but not always. When the V6 Caravans are low on oil they make a high pitched screech until it gets oil pressure because the lifters are still oiled.

 

actually i have that same thing, when i first start my truck up early in the morning the belt squeels for about 10 seconds then its fine, also just curious does ne 1 else have an oil gauge problem? my oil gauge says i wont have oil pressure for the first 3-5 minutes when i first start my truck up but then after warming up a little itll jump up to normal. it has been doing this a while, and after getting an oil change still did it...
