dear dennis thanks for the input ... but no entry of coolant into oil system at all... i went over entire engine several times since the last bleed off and yes my California Model 5 speed diesel does have a buzzer for coolant ... the trigger/sensor is located in combination with t valve off block ... sensor/trigger in main reservoir on starboard side of engine compartment .. there is another coolant mover located in the forward area topside of engine compartment ... it is likely for the under the seat bus heater in rear or it is a supplementary pump .. scott remarked on that item when i was there but i dont recall what he said today and i was too focused on other items so i dont even think the message he spoke got logged ... oh well next time i am up on the hoist i will follow that to its source and end ...

again thanks dennis ... by the way my oil buzzer did go off once with the 1.6 .. that scared the willies outta me .. my over heat buzzer sounds a little different ... ;o) yours
