Hi George, my name is Jason.
The most likely reason for both the coolant loss and the rusty color is the heat exchanger itself is rotting out, and has a hole in it. When that happens coolant and seawater will mix, giving you a rusty color. Coolant will also escape and leak into the seawater side. What needs to happen is the heat exchanger needs to be drained, removed, and pressure tested. Does that make sense to you?
I think that should do it. But I do want to make sure you are happy with my service before you go. If you had a further question on the issue by all means feel free to ask. If not, Just in case you do not understand the way the website works (and some folks do not). You do have to put forth a positive rating in order for it to credit me for helping you. When ratings are not done, the website simply keeps your deposit and they will not credit me. The ratings box is located at the top of the screen. To rate, you must select the star you wish and also confirm it. Please let me know if you run into any problems or errors when trying to do it. If you do have a problem, or if you can not see the ratings box which is at the top of the screen. Please reply back "I rate Jason's service _______" and fill in the blank.
Questions do not close out, so if you have to come back later on with follow up questions to the issue you still can even after doing a rating.
Your question is in the boat category.... What kind of truck is this, i'll get this moved to the proper category for you.
Okay i'll get this moved for you. Sorry for the confusion.
Hi I'm Wayne

what you are describing is a head gasket starting to fail
go to auto/truck parts store ask for a bottle of exhaust gas test
pour in radiator, follow directions on bottle
and check for exhaust gases in the cooling system
also when you have head off,have it magnafluxed for cracks
I hope this helped you

Not Poor/Bad service
Thank you for that
the best way is to remove the exhaust manifold,
and pressure the cooling system to see water in the heads
if you have gas bubbles in the radiator, you have a gasket going bad
Just a follow up with you
