Excessive fan without load

[tabraha]

My PSD is still relatively new to me and at first I thought this was a torque converter deal but after some .org reading this sounds like the big fan kicking in and running at the same speed as the engine once the engine gets hot.

I can leave my house in the morning first thing and even at 80 degrees after 15 minutes of easy highway driving with no load the big fan is kicking in to cool the engine. This isn't normal right?

It does appear that the fan is working and that the engine is running a bit too warm (but not hot) so the fan is needed. Could the radiator be slap worn out at 114,000 miles? What are my best places to look for problems?

Hum, not sure exactly what the problem is. I will bump this up for ya. Maybe the thermostat is not working properly or water pump. I am not tech, so I am just throwing a couple of things out there.

Yeah, that had crossed my mind too. Heck this time of year I could just yank the T-stat. 80 degrees is as cool as it's gonna be for the next few months. I sure hope it's not the water pump. $$$$ Thanks for the bump!

is it hot out? do you have your ac on? i hear a hugh fan noise when i run my ac alot. if not its a bump for you!!!!

i know this is a stupid question, but have you checked your coolant level? 1 gallon low will make these trucks run hot and/or hotter than usual and espeacially with the ac being on. i havent seen the first water pump problem, or a bad t-stat but that doesnt mean they arent out there.

I have noticed a similar issue with my truck. Its not even a year old yet, but in the past couple days the fan has kicked on, and the temp gauges on the cluster seem to be reading normal operating temps. It has been over 90*s since Monday and the dealer says that it is normal for that to happen but I'm still skeptical.

Though I wish it wasn't, I suspect it is normal... Here in the desert it's been well above 100 for two or three weeks now and the thing kicks on whenever I turn the A/C on... Obviously if it's other then later at night or the early morning the A/C IS on and so is the fan...

Yeah I noticed that it was only coming on when I had the A/C set to max A/C.

As long as I'm not by myself I guess that I'll let it slide. I've checked the fluid level and it was OK. I feel like I'm driving an International alright with that sound coming out from under the hood, that's for sure!


Anyone know of a really good radiator for these 6.0's? I might give one a whirl. I need to hook my travel trailer up one afternoon at about 100 degrees and see if I'll still be able to keep the temps in normal operating range. At this rate I might need a set of gauges for a stock engine!

About the only time I hear mine is when I'm pulling something pretty heavy.
