What they said. Thermostat would be easy access while doing the timing belt. Take a look at the cooler above the oil filter. If it's caked in dirt, replace the oring between the oil cooler and the block.

+1 on replacing the timing idler pulleys. My old motor died cuz one of those seized up and caused the timing belt to wrap itself around the crank pulley. Depending on the mileage, you may want to inspect your water pump, oil pump, cam shaft seals, and oil pan seal.

Good call. I plan to get a new oil pan (killer B) and pick up tube, which I recommend for anyone running the 2.5 block's oil pick up tube...seen one of them crack at 40K miles, so now I'm nervous about them. My oil filter had a sandwich block for its oil pressure sensor, and it's filthy above it somehow.

Good advice, thanks all!
