Water pump Gates or OEM Toyota

My 99 V6 just rolled 316k, am looking into my 2nd timing belt/water pump DIY

Engine water pump is leaking coolant. The pulley and drive belt are slinging the coolant onto other components. Highly recommend to replace with factory parts.

Electric water pump is leaking, replace with an oem toyota part dont cheap out and go aftermarket on this part.

I used a gates water pump on mine and have had no issues

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

We used to install gates pump and belt kits, but saw too many leaking water pumps well before they were due for another belt. Switched to aisin kits and haven't had a problem.

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

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.

I had my issues with the 2nd gen (water pump failure)
