Cat 350 c7

I have recently purchased a fleetwood revolution 2005. I have a cat 2004 350 HP c7 engine. I was on a trip when the engine started to overheat. I discovered that the coolant radiator and turbo radiator were packed with oil dry and crud. I was able to use a degreaser to get it going again,but realize it will just happen again.

I know about extending the blow by tube, but was wondering if there was a way to clean the radiator,especially since they are sandwiched together,without having to remove the radiators?

Spray degreaser and a hose just like you are doing. If it is really bad let the degreaser soak for a period of time and then blast it with the hose again.

Your C-7 has the same radiator/CAC setup as the 3126E. Check out this prior post on the subject of cleaning rear radiator MH's and make sure you do one of the slobber/breather tube mods which will eliminate future clogging problems

Welcome to what IMHO is one of the biggest design flaws of the C7.

As has already been pointed out, you will need to do a VERY thorough cleaning of the radiator & CAC, and this must be done annually, at a minimum.

There's also a good chance that your engine oil dipstick has never been calibrated, and you are over-filling the crankcase, forcing the excess oil out of the crankcase ventilation tube (slobber tube), which will then get sucked into your radiator.

After you do the above, many of us C7 owners have modified the slobber tube by either extending it past the radiator or adding some sort of oil blow-by catch can.

I highly recommend you join the Cat RV Club Forum where this issue has been discussed in detail, with many of the discussions saved in the "Files" section.

iRV2 also has a good Cat engine owner's section where this has been discussed.

I have some good info saved on my hard drive at home on this topic. Feel free to PM me, and I can email it to you when we return home.

Happy trails!

Craig

I had a high pressure transmission line leak that sprayed my radiators causing them to clog. Cat had to remove them to properly clean and the bill was over $1600. Kinda takes a lot of fun out of a trip.

Allow me to repeat myself....do some Cat RV Club & iRV2 forum research on the subject. You cannot get a garden hose in between the CAC & radiator.

It really has nothing to do with the design of the C-7, CAT has a good unit there. It's up to the RV chassis manufacturer to provide the specified cooling package.
It's much cheaper to go with a rear radiator/CAC than a side radiator/CAC and CAT doesn't make that decision, the RV manufacturer does that according to their budget.

I was referring to the design and positioning of the slobber tube, which is a Cat design. IMHO they should have gone with a closed crankcase system from the start. The dipstick issue I'm told is the fault of the chassis manufacturer.

I guess I shouldn't finger point, since there are three different manufacturers that could be responsible any particular flaw.

Craig, the oil dipstick is installed by the coach manufacture. It all depends on where the coach manufacture wants to install it. The same goes for the radiator. However the crankcase slobber tube is a caterpillar fault.

Are you sure you have a CAT 350 and not a Cummins 350 ISC? Regardless the radiator and CAC should be cleaned regularly.

Good luck
