I plan to switch out the fan clutch on my 03 6.0 with the 7.3l clutch. I've been shopping for water pumps and came across Dieselsites High Performance model for the early 03 engine I have. Has the billet impeller and claims 25% more coolant flow. Anyone tried on of these??

I have the late '04 version. It has worked fine for me for the past few years.

Bullet Proof Diesels pump is probably the last pump you would ever need, that’s why I put one in my truck.

I too have the Dieselsite water pump for 05+. It's been on for 100k miles, no cooling issues whatsoever. I highly recommend
