How hard is it to change the timing belts on an xt6? did you have to remove the engine? how long did it take, and last but not least, How fast does your xt6 go(with what mods)?

timing belts are not terribly difficult. if everything goes right (cough cough), the only tricky part is the drivers side belt tensioner. easy with two people, get a chance to be a little creative by yourself. i always do it by myself with no problems. the 4 cylinder motors are definitely easier, but the XT6 isn't terrible and doesn't require any special tools - depending how you tackle that drivers side tensioner.

 

if it hasn't been opened up any time recently the timing covers will likely be very annoying to remove. the inserts that the bolts screw into will strip and turn inside the inner belt covers and the bolts won't come out. you'll have to push/pull the actual insert out in that case. or just break your covers and run without them.

 

how fast .....the XT6 doesn't have any problems getting over 100 very quickly. it's not a race car, but it doesn't take forever and requires a slight incline to get over 100. mods won't make much difference in top speed as the top speed isn't all that high. the automatic is geared higher and has the potential to go faster. for instance a manual AWD trans XT6 will run 60 at 3,000 rpms and the automatic AWD will run 70 at 3,000 rpms. i'm making those numbers up, but they are close since i don't really pay attention, but something like that. so at 5,000 rpms in highest gear the auto will be going faster.
