Having IMS/Clutch and flywheel done... opinions?
 
Hi all,
I am having my IMS done as the clutch and flywheel needed replacing. My car has 74K on it. Also doing the RMS and pan gasket plate.
A common issue I have heard about is the water pump. I believe mine is original but not completely sure. What is the failure rate of water pumps and life expectancy?
Is there any other maintenance items I should be wary of?

Thank you!

It should be replaced about every 5 years or 60,000 miles if using a OEM quality WP. Replace it immediately if it leaking or the bearing has play.

Front motor mount while you're doing the water pump. Check the transmission mounts and AOS while the clutch is being done. Do the water pump if there is no record of a replacement. Over time the plastic impeller blades will crack and break off due to many heating and cooling cycles. Then the pieces can travel into the heads and get caught in small passages, leading to hot spots and cracked heads. Have them flush the cooling system as good as they can if there are any broken impeller blades on the old water pump, to get as much of them out as possible.

Good job on your list.

AOS if you haven’t replaced it recently. It’s just sitting there so easy to access with the tranny out.

Motor and transmission mounts for sure if they are still factory.
