just get the belts changed. At least YOU know when they were done last.
I use an app on my phone "car maintenance" I believe to help keep on top of the maintenance records for my car.
honestly it's not that difficult of a job, the hardest part is breaking the crank bolt loose.
Side note: only try this if you're really comfortable with your mechanical skills. To break the crank bolt loose, use a breaker bar with socket, and use the engine to break the bolt loose as in place the socket on the bolt and spin the engine over (without cranking it) it only takes a second to loosen it.
Good luck with the maintenance. Remember check for cam seal leaks and crank seal leaks. I replace them with every timing belt change.Also note if you do the cam seals, DO NOT PUT RTV on the bottom of the seal where the drain holes are in the head. Otherwise you'll be leaking oil again and have to do them all over, and DON"T TOUCH THE 5 bolts on the VVTi cam gear. Just the bolt in the center.
lol please learn from my mistake and save yourself the extra 1 hour of having to realign the vvti cam gear.
