Bought a 99 sr5 2wd(unfortunately, needed something to commute and not break) with the 3.4 with 111,000. Now after 2 months of commuting its at 114,000, changed the oil and when I was at in checked the timimg belt, its shot. Bought a Toyota belt and water pump, and a denso aluminium rad as preventative. I'm going to do the accseory belts and rad hoses also. Anything I should do while I'm at it??? I heard idlers and tensionors are good till the second belt change. Going to be running all of what Toyota recommends. Only issue now is theres a coolant leak but there is no trace in where its coming from, as per new radiator. Any tips and pointers are appreciated, specially with the coolant leak, I was simpling think a rad cap.

I know my way around a vehicle had a few Toyota pickups and many wranglers, with several other muscle cars inbtween, always do my own work as I am young.

Thanks for the help, wells

The water pumps leak coolant.

Nothing visible on the ground or skid plate though?

^ correct. The pumps have a weep hole. When I replaced my timing belt for the first time at 171,000 miles, the water pump body was encrusted with deposits from weeping coolant.

Agree on the water pump. Not that expensive and easy to do when you are in there. Mine was also source of small leak with no visible fluid. Also - might as well do the thermostat.

Yea my parts list is as followed

Timing belt
Water pump w/ seal
T-stat w/ o ring
Timing cover seals
New radiator
Upper and lower hose
Crankshaft pully bolt

For the first change, if i own it long enough(plan to) for the second change I'll do all the idlers and seals. Unless when I get in there, other thing need to be done.

Seemed like it was loosing a lot of coolant, but that's some peace of mind.

Any other tips? Starting this Saturday

All wrapped up, took about 8 hours with a buddy. Made the special tool out of 2*4s and bolts. No leaks. Thanks alot guys.

Strongly considering doing the second timinig belt job myself. I let the dealer do the first one at 170,000 miles. I now have 334,300 on the clock.

Any pointers from your experience?

It was really pretty straight forward. I used the skjos guide and followed it step by step. I did a few things slight different but that was it. Not a hard job just time consuming.

One thing I did differently was not remove the ac compressor, I got a swivel socket in to the thin crack by the starter wires to take the tensor out to reset it.

Also when I out the water pump in, I placed some fipg on the metal gasket. Asking around a bit cause my pump is leaking a bit, that's what seems to have caused the leak.

Excellent. I just found the skjos writeup and read through it. Very comprehensive.

I think I'll tackle it myself.

As said its.not hard. Just take your time and make sure your torque the water pump, pulleys and crack shaft pulley bolt correctly. Rent the half inch torque wrench from your auto parts store and just make the special tool out of 2x4s. It might take a couple but you'll get it and to break the bolt, just put a breaker bar on the bolt and zip tie to the drive side frame then flick the starter.
