Water Pump

Is it possible to change the water pump and serpentine belt in a 2006 Toyota Camry with 4 cyl. engine in less than an hour?

Probably. I changed the water pump and serpentine belt on my wife’s 93’ Cutlass Ciera in about 30 minutes. It has the V6 engine. A mechanic with experience with an 06’ Camry 4 cylinder will be faster than someone with no experience on the same engine.

Highly unlikely. The water pump on your 4 cyl engine is driven by the timing belt.

The 2006 camry 4 cyl has a timing chain, not a belt. Here is a Youtube link that shows how to do it.

Yep! You’re right! I looked up the wrong engine.
