Why I waited till 130K to service my timing belt

[boombapslappy]

Is time a factor when the TB or water pump is considered? My 2000 only has 75k. Should I go ahead and replace it because it's eight years old or wait on 90k?

I've had toyota techs tell me that the only time they've seen timing chains fail is when the tensioner goes bad (like gets gummed up from lack of oil changes/sludging). Just comes to show that timing chains are vulnerable, too, just at a longer interval than TB's, and that the tensioner is often the failing mechanism rather than the chain/belt itself.

I did the timing belt at 58K miles on my 99 because of the number of years. It needed it because of the heat factor, lived in AZ all its life. But I replaced everything and I would recommend that to anyone that did a timing belt service. Why mix old and new parts. The parts don't cost that much.

I agree completely. I just performed the 90k maintenance on my 100 and replaced just about every movable part that touches either the timing belt or drive belt. Additionally I replaced the crankshaft seal. I did the work myself and the parts cost $600 (which includes OEM plugs and thermostat). Time is the biggest investment in replacing the timing belt regardless of who does the work, the parts are minimal. Why not replace a $40 tensioner that has the possibility of leaking oil and causing failure of the timing belt while you have easy access to it? It a pretty cheap insurance policy.

I did my 90K service at 80K because I was going on a 3000 miles round trip and I do not want to have any problems away from home.

The gas for the trip however was about $700, and I avg about 15mph for the trip.

WOW if you averaged 15mph what was your MPG

My buddy just did a tune up for the first time on his 99. His water pump had a leak, ps pump leaks, never changed the tb before, nor had he changed the tranny oil before, but his tranny slips.

Is he the original owner? How many miles does he have?

 

[Michaelmr2]

so if you were to buy a truck today with over 100K on it and didnt have the full service history, its wise to go ahead and to the TB and WP replacements?

 

[badass]

his truck with NO MAINTENANCE history has 160 k and he just did a full tune up last month, he tows stuff too.

Oh and did i mention he wheels the snot out of it, hes broken just about everything in that front end

if you want to do the job yourself, do you have to take the radiator and the fan out to do this job?

No need to be remove the radiator, but the fan yes

 

[socalsuv]

You definitely need to remove the fan / fan shroud. The FSM will tell you to take the radiator out, but its not needed. There will be plenty of room to work with it left in.

Look in the FAQ section and there are two very good writeups on this job.
