Im finally pulling the trigger on the 90k service + timing belt.
After all the "what parts should get changed", etc etc, here's the list:
GETTING REPLACED:
Timing Belt
Serpentine Belt
Water Pump w/ gasket
Thermostat w/ seal
GETTING CHECKED, REPLACED IF NECESSARY:
Left & Right Idler Pulleys
Tensioner
Upper & Lower Radiator Hoses
NO NEED TO REPLACE (according to Head Service guy):
Crankshaft Seal
Camshaft Seal
PCV Valve (was done at 60k maint.)
This is getting done next Thursday. Anyone see something i forgot? Something on the list (or not, for that matter) that DEF. SHOULD GET changed?
I read these thread and want to cry at the number of perfectly good water pumps that are going to the dump.
If you have never serviced your coolant then yes.. better be safe than sorry and ditch the water pump... BUT if you have replaced/Flushed your coolant every other year (like you are supposed to) then chances are that your water pump is just fine. The water pumps on the V8s are incredibly reliable little beasts..
If it brings you comfort... stick a new one in, but understand that you are probably not accomplishing anything other then lightening your wallet.
My dealer ONLY replaces the water pump if:
1) it is leaking
2) he has no record of any coolant servicing
3) it is on its second belt (i.e. 180,000 miles)
4) certain engines with known water pump issues.
He has been doing this for years now, on literally thousands of cars and trucks and has had ZERO water pump failures.
The attitude "well since you are there" is a little daft... Since you are there why not replace the crank pulley or the harmonic balance? or the Alternator?
If you read the maintenance schedule from Toyota USA..
There is NO mention of the water pump with the timing belt...
And 5.5 Hrs! WTF! my dealer did mine in 3 hrs! From the time I dropped it off till the time they called to arrange a pickup wasn't 5 hrs.
