changing engine and tranny fluids?

It's a 1998 vintage RV with only 58K miles on it so it has been sitting stationary more than moving.

Change ALL the fluids.....engine oil/filter, tranny serviced (fluid/filter/adjustmnets), rear differential, BRAKE fluid (flushed thru brake lines/changed) and coolant.

Also check the DOT year date on those tires......new tires if more than 5 yrs. old which I bet they are.

Do you have any previous maintenance records?

If not, it's probably best to assume that the fluids need changing. (Don't forget to also include flushing the brakes and changing the brake fluid!) You could get the advice of a trusted mechanic on the work needed.

Also check the date codes on the tires and inspect/replace them as appropriate. Most motorhomes require new tires due to aging long before the tread becomes too worn down.

98 do all the above AND belts,,hoses. rubber rots.

I purchased a 93 Toyota RV with no service records. I have changed every fluid,filter, belt and hose on it.

Brake and tranny fluid are hygroscopic meaning they absorb moisture, moister is not a good thing in these systems. The additives in coolant break down over time, not a good thing.

I missed the fuel filter and then read a post on someone with a used RV that got stuck because of a plugged fuel filter, so next on my list!

Learn to read the date code on your tires, tires over 7 years old are unsafe!

What ever you decide it's been my experience to NEVER allow the repair shop to FLUSH anything. "Just drain and replace fluids".

I've had them ruin a radiator, break ac line, etc.

The push to flush is just to add more money to your bill. And in any older vehicle it's an accident waiting to happen. And more bucks for them to repair. Just saying.

I would "highly" recommend that you change the front brake lines though.

The brake lines will look perfect on the outside but what happens is the inside degrades. Been there done that flying off an exit ramp MH towing and NO brakes. Common problem with the V-10 chassie. Repair shop knew exactly what the problem was. Brake line looked fine no leaks but the inside was completely shot. No fluid coming thru no brakes for me.:(

I had a Ford mechanic friend tell me that Ford said not to worry about the multi ribbed fan belt until it started loosing pieces of rubber, cracking was nothing to worry about.

I start thinking of tire replacement at four years and not more than five. Most of these will age out before wear out due to all the sitting in storage they usually do. Just sayin'.

I think the fluid changes you pointed out would be good if you do not know when they were done. If you do know when some were done. Just follow the Ford book. Belt inspection would be a very good thing.

I just picked it up today, RV mechanic told me not to worry about the transmission fluid till around 75k miles. Oil has been kept up with but I'll probably change it wen I get back to north FL. Did replace one of the front tires, the rest have dates from 13-14 so they're still good. I did notice something I didn't see when I bought it which was some word rot/rust in one of the storage compartments, other than that everything seems to be great. Runs amazing.

Dont use synthetic trans fluid. It could cause more problems than you want.
