Cooling/Coolant Pump Drive Pulley fell off

[tokayama]

98 Boxster.

Thanks of this forum, I have found how to replace drive belt.

When I remove rear wall cover, I noticed that the belt is fine...

And the coolant pump drive pulley has fallen off.

At the following website, I have found a manual to replace the pully, but seems like it is not easy.

Have anyone ever change it before?

If fixed at the dealer, how much did it cost?

Thank you,

Doesn't look all that hard....simply remove the engine access panel, remove the drive belt, unbolt the old pump after draining the coolant, cut the metal seal, and install in the reverse order. Probably can be done in about an hour, not counting the filling and bleeding procedure.

It's a fairly straightforward job. If you dyi, parts will run just under $300. Pump, Gasket, Coolant. People here have gotten quotes from $500-$1200 for Indy shop to dealer. My local dealer quoted $900. I want to say its 4.5 book hrs for dealer. Plan on it taking longer than that if you dyi. If you can find a reliable shop that will do it for $500 I would go that route.

I changed mine out in Sept. I would guess I had 6-8 hrs into the job working on it 1-2 hrs here and there over the period a week. Access is the biggest issue; it’s tight in there. I found that 1/4 in drive with deep 10mm socket worked best. If you don't want to drain all your coolant pinch pliers can be bought at Sears for about $16 a pair, you'll need 3 pair if you go this route. You will also need an E12 Torx socket to remove the passenger seat. You don't have to remove the seat, but I can assure you from personal experience it makes life a lot simpler. Sears sells an entire set of torx sockets for about $20. When you trim the old gasket a heavy set of scissors works best. My wife had a pair of "Kitchen shears" from Bed Bath Beyond that worked great for this. You also will need to get the car up quite high to gain access to the front of the engine from below.

Good luck
