radiator

hi
I have a 2006 Winnebago journey C-7 cat. 50000 miles I have no over heating problem but should I just drain the radiator and refill with new coolant.?

What makes you believe I don't have that spread sheet?

My engine is under the care of one best cummins service centers in Puget Sound. I'll trust them over a internet expert any day.

I was talking to the OP.

Tom,

Yes, I assume you are using the three way test strips.

They test for:
Freeze point
SCA concentration
pH

It is often the pH (coolant becomes acidic and starts "eating" coolant system components) that triggers a coolant change.

That is what an anode is for.

Every five years ALL fluids should be changed; differential, coolant, power steering, transmission, air suspension desiccant filter,etc.

I agree, with the exception of changing the air dryer desiccant more often if your MH spends a lot of time in the rainy north west. Add the oil in the front wheels if you have it.

Your vehicle came with an owners manual that has a maintenance schedule and suggested fluids. If you would like it to perform as well as possible for the longest time possible, I suggest you read and follow it unless you have specific reasons not to. I heard that . . . . , my friend said that . . . ., I read on the internet that . . . . are not good reasons to ignore the owners manual. Yes, it's that simple!

Your Cat-C7 probably has a coolant filter. If it does, change the filter, replenish as required and leave it alone.
contact you local Cat, service center to know for certain.

If your engine does have a coolant filter, the correct filter DEPENDS COMPLETELY ON WHAT COOLANT CHEMISTRY YOU CHOOSE. If Caterpillar ELC (a good choice with a Caterpillar engine) the filter is a BLANK (filter media only, no SCA). But it in and forget it for 6 years.

Yes, if you choose a "low silicate coolant for diesel with added SCA, the filter may be different (depends on whether your new coolant already contains the initial dose of SCA or not).
