I apologize for the onslaught of questions;

does it matter if I get a thermal or nonthermal fan clutch? from what i understand the Thermal runs only when needed, while the the nonthermal always runs??

Also, is replacing this as simple as it looks? remove the bolts retaining the fan/clutch assembly, then pull out, and vice versa to install???

Here's the explaination from Derale:
"There are two types of fan clutches, non-thermal and thermal. Non-thermal fan clutches engage the fan based on the shaft speed of the water pump. Thermal fan clutches engage the fan based on a bi-metal thermostatic coil, which senses the under hood temperature."

That being said I used the thermal, be sure you have a fan that is designed to go with a clutch (not a flex fan and the hole in the center is big enough for the base of the clutch to go through http://www.derale.com/fan-clutch-fans.html). From my understanding more blades are better = 6 or 7 blade.
