Hey All,

I have to replace my timing belt on my 99SI and I'm wondering should I replace the water pump and tensioner along with it?

If I do replace the water pump, is there much more labour involved or is it relatively short labour?

jdm211

most likely you dont have to change the tensioner but the water pump i would always change when changing the belt

Is the water pump difficult to replace?

once the belt is off its 4 or 5 10mm bolts, and on the d-series i think you need to take off the upper alternator bracket/mount thats attached to the water pump.

Should only take another 30 minutes max once you get the belt off

Thanks for the replies guys... Any other opinions on whether I should change the water pump and tensioner?

szuberi

the only other opinion youll get is not to change the pump and tensioner.

sleeperz

Ok smart ***, lol, anyone agree that I should change the water pump and tensioner? Labour is free so that's not an issue and I'm getting the parts at a discount.

si_ponz

so whats the worry, if u got labour for free and parts at discount...do it all lol

yeah, it's not a big deal, just replace it all in one shot. parts aren't that expensive compared to if you gotta do it over again next year when the WP takes a crap, or even worse if the tensioner seizes and snaps the belt.

who cares about the tensioner, just change the waterpump and timing belt.

you do understand what happens when the bearing in the tensioner seizes, right? engine (possibly)

si_ponz

your right there, you mine as well do it, how much more could it cost for that part? honestly, saves u a possible headache later on!

just change all three when u take the belt out it's really easy to change the pulley and the water pump usually when u change the timing belt u always change the water pump as well it's just easy and only a lil more money and time

Question, how do I prevent the engine from turning over since I'm going to be unscrewing the crank pulley bolt? Should I put it in drive?

sleeperz

Automatic...

Using an impact gun on the bolt usually takes off the bolt without turning the crank. Another method is to use a special tool that holds the crank from moving while you can fit a socket in the middle of the tool to turn the crank pulley bolt off. Side note: be careful not to lose the small key holding the crank pulley to the crankshaft snout.

if you feel un-easy and near Oakville.. i can come give you a hand.

I also have the crank holder tool. If you dont have this tool, put the car in drive, parking brake up and/or step on the brakes (a friend obviiously). If this doesn't work, you'll need an impact gun or a special tool

Well, got the timing belt done, tensioner, and water pump. We did not have a crank pulley bolt holder so the only way to remove the bolt was to remove the starter, jam the flywheel with a screwdriver, and then attempt to remove the bolt, which finally gave off after several attempts. No damage occured to the flywheel, which was a relief too. Definitely a time consuming task!
