Which Water pump Bosch or Carquest
 

My water pump is weeping a small amount now so Im getting ready. Im going to order from Advance Auto either the Carquest new pump for 80ish after discounts or a Bosch new HD unit for 85.99. I believe the Bosch has a 12 month warranty vs the lifetime on the Carquest. Im also going to do the cap and rotor at the same time. I dont know if the opti has been done before by the previous owner or not. 93,800 ish now

Does the Bosch have any description of what makes it "HD" other than being a few bucks more?

Personally, any time I had a car that was stock or with mild mods i would just get the parts store brand with a lifetime warrantly. Unless you have mods that are forcing a lot more heat into the engine than stock the more expensive, slightly higher flow units won't really make a difference.
