Hey there, I was looking for a few semi cheap ways to free up a few hp and save gas, and I thought a good place to start would be the engine cooling fan. I looked around a little bit and found this, though its a bit smaller than my stock fan, I wanted to know what you guys thought. For one, if its a legit website, and two, if the fan is any good, as well as the brand. I appreciate any advice.

2000cfm is a bit low if you ask me...but it might be suitable

 

A lot of people go into installing an electric fan thinking they are going to save money and/or gain HP only to be disappointed. If you are trying to save space, an electric fan is the way to go. But to better the efficiency and flow of the stock fan with thermo-viscous clutch, you are going to have to get a very expensive fan and an equally expensive thermostatic controller. Reason being, the stock fan is only truly driven when the thermo-viscous clutch is heated to its set point. While cruising down the road at typical speeds (45-65mph), the draw on the engine from the stock fan is practically immeasurable. When in stop and go traffic, the fan clutch will lock up and actively pull air through the condenser and radiator.

I have seen a lot of people install electric fans only to end up with overheating problems on hot summer days when they have their A/C cranked. This is because they chose a fan that does not pull enough air.

IMO, your money is better spent elsewhere. I would start with a PCM tune and go from there.

 

I appreciate it, any suggestions for the tuner? I have only found one brand for sure that makes them for blazers.

 

I have read good reviews from PCMforLess.com and Wait4me.com with more satisfied customers using PCMforLess.com. I plan on getting a tune for my Rainier from them.

 

Much thanks to you. I will check it out.
