Timing chain on a 1999 Mazda B4000

I just bought a '99 Mazda B4000 4x4. It has 100,000 on it. Do I need to replace the timing chain on it anytime soon?

Also, I will be changing out all of the fluids in the truck. Is there anything else I need to be doing to an older truck to keep it in good running condition?

Thanks!

I could be wrong but im pretty sure you dont have to replace the timing chain, just pull the cover off and take a look at the sprokets and if the chain is tight.

itll start ticking and thats when you want to replace it or if it jumps timing. mine jumped timing and before i had the money to fix it it broke. so and i have 78000 on mine so its something you can probably look into

Does a '99 Ranger/B-Series have a timing chain or a timing belt on it?

A 99 has either a pushrod 3.0 or pushrod 4.0. Which do you have?

Either was it has a timing chain.

The 4.0 might say 4.0. Well at least the SOHC motors do.

A question I have often wondered about.

I know vr6's in VW's have chains and guides, do 3.0's have guides?

I may want to do my Tchain soon.

He has a B4000, that means he has a 4.0.

The B 3000 is a 3.0.

You have 3 timing chains. Two up front and one in the back.

So do these engines utilize chain guides? Those are usually what breaks with chains.

I think only the SOHC engines use chain guides and tensioners but I'm not sure. It already is a problem in my truck as well as many others. Search timing chain rattle and you will see what I'm talking about.
