If you have any hesitation doing this, then don't start it. It's a bear of a job, detailed, and time-consuming. Figure out a dollar amount for worry, effort, and 'opportunity cost' for your time. That should help with the decision.To continue with original poster's question, I am a fair shade tree mechanic. I've personally done three timing belt changes on my 2002 Hyundai Elantra (currently 293K miles). I have ALLDATA service for my 2004 Tundra V8 (currently 110K miles). I have to be honest, I'm a little intimidated by this. You have to take out the radiator, a/c compressor, suspend the p/s, alternator .....
The instructions call for three special tools/tool sets. Do I really need the special crankshaft pully puller or will a standard craftsman three arm work? To stabilize the crankshaft pully it calls for a special spanner. I've used a jury rigged setup on the Hyundai for this but not sure it would fit here. Another special spanner type yoke wrench is called for removing camshaft timing pulleys. Bye the way, why do I want to do that? Can't I just slip off old belt and put on new belt? Are there workarounds for these special tools? I don't want to tie up $200-$500 on single application tools.
Another problem is I've got a coolant leak somewhere. The water pump is suspect. So it would be opportune to change the pump with a timing belt change.
I think I'm really begging you guys to talk me out of trying this and convince me to just take it to the dealer. I'm new to forum. Thanks for any advice.
