3K trip over 2 weeks, should I do this service or wait

[Leroy Eckert]

The Primus is not a part of the engine cooling system, at least it isn't on
mine. There should be two small white plastic bottles at the rear of the bus up
high that are the reservoirs.

So in a 1992 WB40, the Primus antifreeze is also part of the cooling
system? For some reason I thought they where seperate systems and
used a heat exchanger between them. I will go out and fire up the
coach now and run all the systems so the fluid gets circulated as I
am going to town in a little bit to pickup test strips to test the
balance.
