I'm "restoring" a 98 camry 4 cyl. with 200K miles I picked up for free. I'm going to use it to keep the miles off of my gas guzzling trucks.
So far I've:
Cleaned it as good as a possible. Previous owner spilled food and drinks everywhere, lots of pet hair.I think I went through a whole bottle of Frebreeze

Washed and waxed, I don't think it ever was waxed in 10 years
Put in new sparkplugs
Changed the oil
Drained and filled the tranny a couple times until the fluid came out red then changed the filter.
Changed the tranny fluid in the front diff.
Flushed the brake fluid, pads still look good.
The P.O. said she changed the timing belt around 120k or maybe 140k miles

so I figure it could use changing. I was going to replace the water pump, thermostat, and flush the coolant. I have the tools and have experience with timing belts on other cars. How hard is the 4 cyl Camry? Any tricks I need to know? How long of a job is it?
Thanks
