Installed trans now leaking coolant NEED HELP quick!!

[Killian]

Okay here is the deal I just swapped my transmission from an automatic to a manual, this was not the problem. The problem is once i finally got the manual trans lined up and pushed it in i started dripping coolant from the timing belt side! keep in mind the motor has not been run for over a month and i only replaced the timing belt tensioner a week prior and of course had to remove all of the belts to do this, but the leak was not there until i slid the transmission in what could cause this???

It could be from the waterpipe/water pump o-ring connection or from the pump itself. It also could be from the oil cooler. My o-ring started leaking one time when I replaced a clutch. I guess I knocked the pipe hard enough to make the aged o-ring leak.

Sorry to be a bit slow what o ring are you referring to?

He said "waterpipe/water pump o-ring connection" which means you'll want to look at where the two meet. Luckily (?!) that's one of the few places a leak could be caused while installing a clutch. There's not much else you can bump from the other side of the motor. Though you may have a leak elsewhere and it coincidentally just became obvious today.
