Replacing N55 waterpump & thermostat

oneBIGtoe · 10-28-2018, 02:15 PM

Hi guys, water pump is leaking and need to replace. What I would like to know, is there anything else I need to order & replace other than the pump, replacement bolts & new thermostat?

Coolant. You could do the expansion tank and hoses too if you really feel like it.

That’s all you should need. But if any of your coolant hoses have been in contact with oil from a leaking oil filter housing gasket, now is a good time to replace them. Be sure to use OEM blue coolant. If you use the typical green you’ll be repeating the job much sooner.
