Hi all. I'm about to replace the water pump and thermostat on my 2018 expedition. Where is the most reputable place to buy parts from. I know ford redesigned the thermostat recently and would like the updated one. Also is there any other parts that I should replace while I'm doing this? Thanks
Have you tried a dealer, using your VIN? Or, worried about gouging on part’s price?
There are several online Ford parts sellers, such as FordPartsGiant.com (I have no connection to them). They sell from a variety of Ford dealers that sell parts cheaper than list. The site allows you to enter your VIN, which ensures the latest, updated part is shown.
As a suggestion - don’t forget to replace the engine coolant (don’t reuse at this point). The initial change recommendation is five years (I believe)
Since you have to remove the drive belts, perhaps replace them too? They are stretch-to-fit.
