I hate to be that guy but as a guy who does this for a living I must interject, you can do it without the tools if you mark everything like you are referring to. It’s the same way we do all cars even with the tools, mark the belt and pulleys and transfer the marks to the new belt and line the marks up and if you marked it right it’s good to go. The tools are there so if it’s off a tooth you can put it on correctly. The tools are only TrueType a must if you take off the cam pulleys r the belt is off by a tooth otherwise it’s no different than any other timing belt. As a European repair shop we do a LOT of timing belts, just last month we did our first 2018 Volvo 2.0 it had 120k miles and we had to get the procedure from the dealer because it wasn’t in Mitchell or alldata yet, we did 4 of the newer TDI’s in the last month alone
My answer was solely based on the
standard recommended practice of replacing the water pump when replacing the timing belt which does require the removal of both cam pulleys.
When both of the cam pulleys are removed, any marks or tooth counts are totally worthless and the engine MUST be retimed correctly using the timing pins as outlined and explained in detail in the Factory Service Manual.
Why would anyone
NOT replace the water pump when going to all the trouble and expense to perform a timing belt replacement service on this engine is highly unusual indeed.
Yes, if you don't remove the cam pulleys to replace the water pump, you can mark all the pulleys, count the teeth, etc..but why would anyone take that chance....
The water pump on these engines have been known to fail, leaking seals, or worse yet total bearing failure which causes catastrophic failure of the timing belt and subsequent broken rockers etc...repairs gets
very expensive when this happens.
If any shop is only replacing the timing belt and leaving the water pump untouched, they are doing a huge disservice to their customer IMHO.
If you search LOSTJeeps, there are horror stories posted in the past concerning water pump failures causing total timing belt system failure....I don't make this stuff up!
But as always, it's your vehicle, you are your own warranty provider and if the owner wants to cut corners and take chances with expensive engine failures, so be it...
