Tune ups

Hey guys I have a 99 tacoma 4x4 with the 3.4 in it. I'm getting real close to a hundred thousand miles. I was wondering if that is a interference engine (where if the timing belt breaks the pistons will bend the valves). I'm probably going to give it a tune up. Any ideas on what should and shouldn't be replaced, or advice in general to increase performance and life expectancy of the truck would appreciated.

Thanks

 

i just did this at like 125K

fuel filter
spark plugs
coolant exchange
diff fluid
adjust rear brakes(if not needing replacement)
rotate and adjust air pressure
tranny fluid if its been changed regularly
seafoam also(before you change the plugs)

timing belt is reccomended, but i dont have the money for it right now.. if you have the time and tools you can do it

 

i should probably get on that then!

 

What Chris said about the timing belt, every 90K miles. Major maintenance is performed every 30K.

 

So when I tear in to get the timing belt out should I replace the water pump as well or should it be good for another 50k miles. Also can a guy time that motor? I don't know if it's possible assuming the timing is run by the computer. Just wondering if there is a trick to it.

 

might as well change water pump while you are in there. I'm not sure about a timming trick, all i did is mark TDC and hoped nothing moved.

 

If you do the T-belt do the this as well.

.1 T-belt
2. Water pump
3. Cam/crank seals
4. Tensioner and Idler pullies as well.
5. Belts/ hoses
6. Radiator and Block flush.
7. Oil Flush, with tranny atf fluid trick...

 

Thanks guys. Any tips on what brand and/or type of (water pump, spark plugs, plug wires, belts, ect)

 

1.OEM if you find a whole sale deal.

2.Plugs and and plug wires NGK if you can not get OEM...
2. Gates or Good year as they are proven good. for belts and hoses

OEM last the longest more of the time, but never pay full price...

 

I just replaced my timing belt
