Is it Mandatory to Change the Water Pump when changing the timing belt?

 

No its not manditory but you should look and check for leaks around the water pump while you're in the area.

 

ya not neccesary BUT if you have most the motors front pulled apart.
its a GREAT IDEA to replace the water pump, tensioner, belt, and also the most forgoten upper and lower oil seals for the crank shaft and the cam shaft. otherwise a leaking oil seal can well..... leak oil which is harder on the new belt and makes it alot easier to slip a tooth...

if youve already pulled the motors front apart then these little parts are just cheap insurance!
they dont cost much when it comes to the posible "future" issues.

 

don't complain just do it now its easier than later and scorching your engine

 

I didn't. I'll just change mine when it breaks since it really not that hard.[&:]

 

I agree with Addiction, if you've got the timing belt off you might as well change the pump and seals. It's not a fun job to have to do twice...

 

they change the water pump with the timing belt because you have to take the timing belt off to replace a water pump. that is usually around 4-5 hours labor. so doing it at the same time is the best choice.
