For the 99.5-03 ALH engines, the manual transmission cars from the factory where supposed to be done at 60,000 miles and automatic transmission cars at 40,000 miles. When replacing the TB, a kit can be purchased to upgrade to 100,000 mile intervals. 206,000 miles in my case was way over due on a TB and pulleys only meant to last 60,000 miles.I wonder why the timing belt changes in the UK are specified at 60,000 miles. i read about much higher numbers in the US / Canada, though i do see more evidence of cambelts breaking as well based on posts i read.
cant imagine the belts are any different?
