air filter
cabin air filter
The tools needed
Torque wrench set good from 5 ft-lbs to 180 ft-lbs (I bought 2 CDI wrenches online, the 752mfrmh and 2503mfrmh after much research on brand quality)
10, 12, 14 mm wrenchs
10, 12, 14 mm deep 3/8 sockets with 3/8 ractheting wrench
3/8 socket extensions,about 3" and 5"
10mm allen head socket 3/8 or 1/2 (To remove timing belt idler sub-assembly)
22 mm deep socket 1/2
1/2 breaker bar at least 18" long
Locking chain wrench or -plumbers chain wrench with breaker bar-
Rubber to protect crankshaft balancer from chain wrench (I used an old bike innertube cut into strips, layer at least 3/8" thick)(To loosen crank bolt, I let the locking chain wrench put force on the thermostat housing and I put a good 1/2" of rubber to protect the housing)
Crankshaft harmonic balancer puller (I bought a set at harbor Freight for $15)
gasket scraper (for water pump change)
crankshaft seal punch/press (Can use 2" pvc pipe cut square with wood to hammer on center of pipe)
string or house wire to hang accessories
adjustable pliers for hose clamps
shop light
drain pan for coolant plus storage containers for old coolant
vacuum hose to drain coolant from engine drain plugs without making a mess
lots of vinyl or nitrile gloves
I believe from changing all idler pulleys and water pump that the new bearings reduced friction and helped gas mileage maybe up to 1 mpg. At 100K one idler pulley had rust on the indside lip and the other had dirt and grease covering the inside lip. Water pump wasn't leaking and looked fine, I replaced it anyway. I needed 2.2 gals of coolant because I drained the coolant from the engine as well, there are two engine drain locations, so coolant doesn't spill everywhere when removing the water pump and oil cooling hose. With 1/4" of rubber protecting harmonic balancer the locking chain wrench still put small dents on several of the "v" channels so use at least 3/8" or a thin peice of metal over the rubber. Luckily, the dents were small and didn't mess up the harmonic balance.
Follow the TSRM for timing belt and water pump change and torque all bolts to correct specs and you will be fine.
