2006 Ford V10

[ferd3]

I have a 2006 Damon Challenger, with a Ford V10. We purchased this MH in January 2010. We are new to RVing, and have only taken our MH on 5 short trips. We purchased the MH in Kennedale, and drove it to our home in San Angelo, Texas. We took the MH on our first outing in February. Then the next 3 trips were in May and late July. On the last 3 trips I hear a noise that sounds like the engine speed increasing, however the RPMs on the tac do not increase. After a period of time the noise fades, and all that I hear is the normal engine sound. After a period of time the noise retuns, then fades again after a period of time.

I've gone through the owners manual hoping to find out what this noise could be, and could not find anything about this.

I suspect that it is a cooling fan for either or both the engine and the transmission. I watch the guages closely and both are at normal levels all the time.

I also suspect that on my trip home from Kennedale in January and the trip in February, this noise was not heard due to the colder outside temperature and therefore there was not a need for the cooling fan to activate.

Am I on the right track?????

Thanks,

Ferd

ferd3 , You are correct.

Mike,

Thanks for the reply.

If the engine fan is kicking in and its less that about 110 outside, then I would say you probably have an overheating problem. I have never heard mine kick in and I have pulled some really big mountains.

You may want to get another temp indicator to check it. I use a Scangauge II that just plugs into the OBD port.

My 08 Ford V10 fan does come on going up Mountains and is quite loud. But only on steep grades, even in the 113 degree desert heat it does not come on. I can only see a slight increase on the heat gauge when the fan comes on. Clutch could be bad on fan.

Thanks Wizard and Safari1 for the additional info. The last 2 trips were in 100 degree temps, but I'll check the engine temp and also the fan clutch just to make sure.

I hear my fan come on. Mostly pulling hills, rarely in the flat. It's not real loud, but I do hear it.
Mt temp gauge never moves, except to "mormal" after a cold start. I've heard Ford programmed it this way on purpose, for reasons beyond me they just don't move until the rig is seriouly overheated, then they go right to the top.

Yes, if you want to actually see the engine and other temps, you need a scangauge.

I have never been a fan of Fords guages. They are like a idiot light with needles. Start the engine up and rev the engine and watch the guages the oil presure will not change.

Thanks for all your help. I have ordered a scanguage. Hopfully it will be here in time to use it on my next trip (Aug 15-19).

One question, is there someway to test the fan clutch to determine if it is working correctly?

I have the same sound on my 2006 V10 and it is definitely the fan. Comparing the scan gauge and temp gauge, the actual temperature (scan gauge) can increase from 192 F(usual) to as high as 208 F (4,000 RPM on a long hill), and the temperature gauge will never move. The fan usually cuts in about 200-205 and back out at 194 or so; cools down fast!
