With these cars, it\u2019s less so staying on top of the regular service items from the dealer - and more so staying educated on all the little unspoken chickenshit maintenance items that VW doesn\u2019t outwardly talk about.

Cons: unspoken maintenance items

Vehicle: Volkswagen

I actually just changed the pump on my 2018. With the pump/thermostat assembly, and a collection of specific tools, it cost me ~$900. I was quoted 2k by a dealer so I saved a good chunk of change. All-in-all the job is straightforward, save plenty of headache with disconnecting hoses and wire clips.

Pros: straightforward job

Cons: disconnecting hoses, wire clips

Vehicle: Volkswagen Golf

The Aisin kits are fine. I would not use a gates kit; the water pumps are junk and so are the tensioners

Pros: Aisin kits are fine

Cons: water pumps are junk

I want to share a brief but critical report regarding the recent replacement of the engine's electric water pump (EWP) on my Prius Gen 4. The analysis of the data logs revealed an alarming scenario; the new aftermarket pump's performance was completely unreliable, showing clear evidence of torque failure and instability. I had no choice but to purchase the Original Equipment Manufacturer (OEM) pump from the dealership (it was stamped with the AISIN logo). The problem was instantly and definitively solved.

Pros: problem instantly solved

Cons: unreliable performance, torque failure

Vehicle: Toyota Prius
