Fleetwood Providence Overheating

We continue to have problems with our 2006 Fleetwood Providence overheating....after only going a couple of miles. We have replaced the thermostat as well as the water pump. We have finally decided that the radiator and CAC is severely clogged. I've been reading on the forums here about using Simple Green as a cleaner.....is Mean Green the same thing? We don't want to use anything that will do more damage! Also, a mechanic with Caterpillar told us that they flush their radiators with Cascade; just pour it in and let it boil out your radiator...haven't tried that yet...wanted to see if any out there has done that and what the results were? Thanks in advance!!

I had the same problem when I bought my Providence back in 2006. I recommend Simple Green Pro HD, sold only at Home Depot. Cleans extremely well and is safe for aluminum.

Cascade is used for cleaning the INSIDE of your cooling system (after an oil cooler failure etc.). You need to clean the outside.

I have a very thorough method of cleaning my radiator/CAC that I have saved on my computer. I'd be happy to send it to you. PM me an email address if you're interested.

If you do a search on here, you will find picture's of radiator's and CAC and what they look like when taken apart. After taking mine apart, And saw what it looked like in between the two, there is no way to properly clean them without taking them apart and removing for proper cleaning and inspecting. I know it is a bit of a job, but better than over heating and a roadside breakdown and a tow, then paying high labor rates on the road. JMHO

sewfine,
Cleaning the CAC and the radiator fins in many coaches is one of the toughest things there is to do. In many, it's almost impossible. If you think you can do it, thoroughly and efficiently, while both are in the coach, more power to ya Bud. On mine, the only way was to remove them. Good luck on that one. Now, as for inserting ANYTHING, ANY CHEMICAL other than what's supposed to go in that cooling system I think, is taking a chance. I'm no CAT tech or, no chemist but, those engines have certain restrictions on the cooling chemicals etc.

If I were you, just for your protection and, your engines protection, I'd get a second "Professional" opinion on adding "Cascade" to the internals of that engine. Just a suggestion here. Good luck.

And here is a great thread on this to read Rear radiator / CAC cleaning
Pretty much my opinion too. While ours, an '04 Itasca Horizon 36GD with the C-7 330HP CAT, did not over heat during regular driving on flat ground, it did rise in temp easily on even mild grades during mild temps. Long story short, as he stated, there's really no real, efficient way to really get both of them, the CAC and the inside of the radiator truly clean.

Many have done what they think is a complete job but, I know there was no way to do it on ours. So, out both of them came. I did all the work myself. Not an easy job, which is par for me anyway. But, it took a lot of industrial cleaning compound, as in ZEP CITRUS BASED DEGREASER and, a pressure washer to really get it all thoroughly cleaned out.

So, just what kind of effort is needed to get the OPs radiator and CAC really, really clean, remains to be seen. In some cases, some have cut an access door in the top of the radiator shroud and done things that way. I couldn't even do mine that way due to the fact that the shroud is really tucked in and under the head section of the bed.

For the OPs sake, I do hope he can get it clean without removing the two but, as stated, it's pretty tough to do. Good luck.
