Cat C12 505 HPOverheating

Yahoo Message Number: 70914
I just bought a 2002 Affinity. I have some questions

I was watching the coolant and oil temp in the engine. The lowest the coolant got was 190 and the oil was 204. Going up the three sisters in Wyoming the coolant got up to 205 and the oil to 220.

How high is the save range.

No. 2

I saw the generator start in the bedroom. Is there one in the living room or driver's area?

No. 3

Steps were working and stopped. Ideas?

No. 4

I got the backup camera to work, how do you get the navigation going?

What kind of MPG should I expect.?

Thanks for your help. I have been following the group for a week now. You all seem very helpful

Hi Sam,

Not going to be able to help you with your questions, as my Allure is a different animal then your unit.

Wanted to welcome you to the board, and concur this group is great.
-Generator Start - In the allure, is on the same panel that shows the waste/water/lp levels, and controls the hydro-hot, over the front door on my unit. Generator's should have a hours odometer time number roll, usually close to where the switch is.
-No experience on Cat temps, others will be able to help you on this for sure.
-Door steps could be a number of things. From a fuse, to a switch. You said it was working. When you try it, do you hear anything at all - as if it is trying to do something?
Last tip was given to me when I first got our 04 Allure about a year ago. I was told to go grab a cup of coffee, a comfortable chair - and then start working my way thru the great documentation that CC provides. Hope you have these boxes and manuals for your coach.
Bob has a 02 Affinity, and check's in often - suspect he'll be happy to offer input too.
Again, welcome to the board, and enjoy the coach. It is an elite coach in any camp setting, hope you have a smile on your face (to offset the dent in your wallet!).

Have fun, be safe,
Smitty

Welcome to the forum and CC ownership!
Those numbers are about right for our C13. Our engine cruises around 190 and on hills will go to 204-205 before the fan kicks into high and drops the temp. Have hit 210-212 on a couple of hills in AZ when it was 110 degrees outside and the buzzer comes on to tell me to slow down. If you call the CAT RV Hotline 1-877- 777 - 3126, they can tell you what is normal for your engine. They will need the engine serial #. You can also transfer the registration to you in case of recalls, etc. While on the phone they also may be able to tell you what service has been performed on your engine if it was done at a CAT dealership.
PS Include your coach # in your signature when you post. Makes it easier for us to help sometimes.

Sam,

I have the C12-505HP in my 2004 43' Intrigue (built in July 2003) and oil and coolant temp numbers you quoted are consistent with what I see when moving down the road. I think i have even seen the oil go a little higher but cannot remember right now since I only drive it twice a year.
I have a control panel above my entry door which includes a generator start button.
Be sure that the steps are kept well lubricated (Kwikee provides a reasonable explanation on why to use Kwik-Lube). That is probably not the cause of your problem but definitely a good starting point 0 lube up and try to pull or push. If that isn't the cause then most likely an electrical problem.
MPG is something that you just cannot worry about owning one of these beasts. And, MPG performance depends on a whole lot of factors for which have all had their fair share of discussion on this site. However, for your info on my coach the Silverleaf consistetly shows around 4.6 MPG unless I have been boogying down I-5 for an extended time on cruise when I have seen the high 6's and one time even saw an 8 (had to be an abberation). That is the good news. You can bet the first time I tried to climb the Ashland grade in Oregon and saw 2.7 MPG on the Silverleaf it took the wind out of my sales but you get used to it. With fuel prices the way they are today I just figure $1 a mile and hand over my credit card at the fuel stop, relishing in having the joy ownership and not the pain of ownership.

Enjoy.

What are you watching the temps on? The analog gauges? Or do you have a Silverleaf? The analog gauges are useless. On the Silverleaf, 205 coolant temp going up steep hills is totally normal. Mine goes to 210 under these conditions.

Do you know this number? We just got the coach. It seems to be in pretty good shape.

Our 2003 Magna Resort 42' 505 is probably very similar to your '02 Affinity. For some reason, my Silverleaf unit was originally programmed to read out in degrees Centigrade (for coolant only for some reason), but it usually runs in the 95-98 degree range, which is about where yours is running on the Farenheit scale. Climbing steep hills towing a full-size Grand Cherokee, it will rise to 102-103 sometimes which, as you know, is over 212 F, but then the cooling fan kicks into high and brings it back down into its high normal range, around 99-100. The only time I have gotten a hot engine fault was when the fan controller unit failed when we were back East. Once I replaced it, there have been no problems. The oil temperature typically runs about 20 degrees higher than the coolant, so you seem to be right in the ballpark there.
If you have the same Silverleaf unit I do, you can probably push the "info" button while the unit is operating, either while the coach is running or, alternatively, by activating the Silverleaf manually with the switch on the dash. The first screen usually shown upon pressing "info" is the generator information, and from there you can turn the generator on and off using the rotary dial to toggle between start and stop, and pressing in on it to activate either function.

The step problem is probably a fuse, but I've never had the problem myself, so check the electrical system diagrams in your manuals to see where it should be.

We usually get between 6 and 7 mpg over the long haul, and I do quite a bit of mountain driving. Your mileage improves drastically if you stay in the 55-60 mph range, but I'm often too impatient to do that.
Once you get into the 65-70 mph range, your mileage will drop to around 6.0-6.2 or so. As someone else said, just figure a dollar a mile these days and be happy that you always have a place to stay, a place to cook and eat, and probably no bedbugs!
