Ok, so i smelled a little bit of antifreeze on the way home today, i pull in, look under the hood, and my fan has 3 blades that are missing decent size chunks [anywhere from 1-2 inches].. not enough to make the engine overheat, but they arent all right in a row, however, the chunks are in the same spot and the same size in each blade. could something have got in there to make this happen? how else would such an occurence happen. also... there was coolant sprayed on the battery, and quite a bit on the shroud, and on other various parts and within an hour of sittin, there was a small puddle on the ground. can anyone point to what this might be from, or is this fluke accident. please help. greatly appreciaited

i dont have a camera this weekend.. but anyway, took to a buddy of mines mechanic garage and was diagnosed as leaking water tanks. the fan blade chunks were caused by a piece of the shroud coming loose but that is a seperate incident. anyway, does anyone know where to get a cheap fan, and also how much 2 new water tanks + labor would run me? thanks

check www.rockauto.com for the fan

Go with a taurus e-fan and simply get rid of the clutch fan.

nooooooooooooooooooooooooooooooooo do not use a e fan they suck they dont save a thing and dont work at high rpm the blades go flat and can go thrugh the raditor and cause big big trouble

[dmbrisket 51]

^ my honda uses 2 of them, and ford tauruses use them... your saying that taking a load off of my engin doesnt save me anything? i think it does, and also, how is a Plastic blade going to go through my aluminum radiator? if it doesnt help or is nothing but bad, why would companies continue to use them?

[redwheeler]

the gas savings is like nothing u couldent run a weed wacker on the savings the fan does nothing at high speed flat blades dont move air

[dmbrisket 51]

its not gas your trying to save (atleast im not) on a flat stock moter removing the fan adds 15 horses, im trying to push every poney i can and save room doing it

The only blades that go flat or break are "flex fans" not regualar e-fans. They are thin metal not high density plastic. E-fans are a good upgrade. provided you stick with a good flow one. The Taurus e-fan runs 2800 CFM low, 3600 on high. More than enough to cool our engines.
They remove the load off the engine and you regain about 4-9 hp for your motor. (Regain, not create). E-fans have been in use a long long time, if there were that much of a problem,. no one would be using them.
You obviously don't know much about e-fans.

Not discrediting your advice, but when does the efan recover horsepower when the fan is practically free-wheeling when the engine rpm is anything above idle?

[rlith]

Actually it will kick in above idle as well. That said, less weight=less resistance. Physics 101. The e-fan has been proven over and over and over again to help in that regard. But as stated, you are actually freeing up power, not adding power as some people think.

The thermostatic fan clutch on the Blazers is another great BorgWarner part (not made in my plant though). BlazerLT is pretty much right... the load on the engine is minimal except when the temperature of the air coming out of the radiator is high enough to engage the clutch. This isn't to say that an electric fan might not be slightly more efficient over time if it were really well designed, but generally speaking, driving a load by an almost direct mechanical connection (i.e., the fan clutch) only when needed is going to be more efficient than generating electricity with an alternator, transmitting that energy through copper wire, and then converting the electrical energy back into mechanical energy via a permanent magnet motor, all steps that involve significant losses.
