No foamy oil (water in oil), Have not noticed any water from
exhaust. Temp. has been fluctuating for a while now. goes up to 223
when air is off and second fan comes on it cools down to around 200%
Thanks Don.

Check for dexcool crust around the water pump housing(crossover) at
the junctions with the head and block on both ends. They are a bit
hard to view, but can be seen. My other recommendation would be a
block test, these engines tend to loosen at the head gaskets due to
thread failure in the block. Any cold misfiring at startup?

I'm not sure what dexcool crust is but will take a look when the rain
stops. Not sure how to do a block test ether. not having any
misfiring that is noticeable. I did change the radiator cap today to
a 16 lb. cap. that is what is called for in the manual. It had a 14
lb. cap and it was weak. I did mix the anti freeze with out realizing
it. I have red (five year) and put in about a quart of the green,
(three year). they should not be mixed, could that have anything to do
with it loosing water?

Dexcool crust is just dried orange coolant residue, The block tester
is a special tool, available at NAPA or other sources. It is filled to
a predetermined level with a special fluid and placed over the
radiator opening(some fluid may need to be removed to prevent sucking
up coolant). Air is drawn through the fluid with a bulb that is
included, or positive cooling system pressure, and the fluid reacts
with the presence of combustion gases and changes colors. The fluid is
usually blue, changes from green to yellow determined by the severity
of the internal leakage. The mixing of the green into the long life
should not contribute to any fluid loss, the fluid is either leaking,
or being consumed internally. My feeling at this point is, if you
don't see any external leaks, you might consult someone and tell them
you just want a block test. It can also be done with an exhaust gas
analyzer held at the radiator opening.

Thanks for the info. It looks like this is getting over my head so I
have made an appointment at the auto shop to have it checked out. I
did get what I think is good advice on this site but I'm limited in
both knowledge and ability so I must pay for what I do not know or can
not do. Isn't that always the way???
