Water pump Gates or Hepu

my hepu has been in for 9 years with zero issues

Hepu pumps are the best.

Water pump if stock would have a plastic impeller known to fail, but you can find metal impeller options from Graf and Hepu brands and from other aftermarket brands too.

Update: it was the water pump. Got a new Gates water pump (screws and gasket included). Installed it, no sealant or anything. Works flawlessly. Not a drop anywhere.

I used the gates kit from rock auto including the gates water pump… Car seems to be driving fine for the past few thousand miles since install.

I only use gates kits on any HDI I work on. Out around 30 fitted to friends and family cars I had one water pump bearing fail after 4 months they changed it with no issues but as it was a home fit not garage no labour cost offered no other issues.

Did hear Gates did have a bad batch of 2.0 Blue HDI OEM water pumps with impellers coming loose

I also had the Gates pump leak within 6 months. The input shaft seal was leaking. Gates used to be a great brand but these pumps are garbage.

I’ve gone through about 3 water pumps all within 10-30k kilometres and each time it’s something leaking other than the gaskets. Either the freeze plug starts to leak or the actual water pump does. Luckily i bought it through napa and they’ve been giving me new ones under warranty but the job takes about 4 hours and each time i have to buy new coolant which is starting to get expensive. The cheapest OEM pump i’ve found from mopar was 1000cad which in itself is crazy because the napa/gates are about $170

I am dealing with a similar issue right now on my CJAA which I changed the timing belt in April this year. Leaking from same spot. Hepu waterpump.

Good choice on going with Aisin. I had to redo the job on mine after 2 months when the shitty Gates water pump started pissing out the weep hole. Will never buy another Gates pump again.
