Cooling Fan Noise

M

GUEST
just bought a new Avalanche yesterday and I am very happy that I bought one. I have noticed that the engine cooling fan comes on all the time (for a short while) although its cold weather (45 F). This fan is little noisy while the engine is super quiet. What should be the normal coolant temp - mine reads little below 210 F all the time. Is a flex-a-lite solution a good idea for better cooling and less noise?
Thanks for any infos. I really like this forum, learned already a lot before I even bought the vehicle. My AV is orange metallic and I love that color but most people think I am crazy - seems everybody likes pewter, grey or black.....

I show just below the center 210 mark as well for the past 9 months or so... (Hot Atlanta Summers, and normal winters)

Should be fine... I don't "HEAR" mine come on that much, but I will pay more attention and report back if anything strange is happening

Welcome to the club mahalkita - I have the flexalite fans on mine and they are substantially quieter and open up the engine compartment quite nicely - the install is not too bad except for removing the darn clutch. ;D

Hi Mahalkita, Welcome, I haven't noticed any noise from the fan at all. I have had my Autotap on mine (just playing) and noticed very steady coolant temperature never went above 194 degrees even after idling for 45 minutes I was impressed with the cooling capacity of the Av. Having mine over a year I have never seen my temp gauge hit the 210 mark. Good luck and again welcome.

So you have electric cooling fans? and not the regular mechanical fan w/fan clutch that is belt driven?

gandolphxx has electric fans because he put them on to cool his supercharged monster.

Around 200 is very normal operating temp - remember you have a 195 degree thermostat.

Thank you all very much for the warm welcome to the club! This is my first American car (made in Mexico) - before only Toyota Landcruisers. We had a LC club as well, so I am very happy to find also this AV club. It really helps a lot sharing infos, getting to know the little important things...

@TexAVfan
No I have no electric fan but the clutch kicks in every now and then. Just noticed some strange noise because the engine is super quiet (not like a Toyota LC)

Is 500 $ for a pair of electric fans not a lot of money, do they improve on power gains? Here in Louisiana it will get warm in a little while...

I would leave the fan that is on it unless you have done some mod that requires you to change it. gandolphxx needed the room and pulley space but it would not be of big benefit to you, course it would take away a small amount of drag on the engine but I dont think enough to justify the expense.

I think I read one time that if you plan to offroad at all then the electric fans would be a NO NO. The stock fan does just fine in the 110 degree heat we have here in the summer.

Like it was mentioned before unless you plan to supercharge it and not go offroad (no water) then the electric fans would be OK.

Mine makes a bit of noise when it's cold, but it doesn't keep doing that for long.

Mine sounds like a jet plane intake for the first 60 seconds  :eek: But it only does it once in a while. I have not been able to figure out a pattern ???
