Warren,
Thanks for your reassuring reply. Now I know how to proceed
Next, pardon my ignorance but, why the testing sequence in the order.....
coolant pressure, compression test and then, leak down ?
What is an adequate test for oil in the coolant, just examining the expansion tank fluid, opening the radiator cap for a peek, draining some radiator fluid or what ?
Finally, I am not certain because I wasn't looking for anomalies..... but seems like I did add a little coolant to the expansion tank this summer but that could have been another vehicle. But now that I am concerned..... I'll watch it and if I notice any 'usage', I'll report it.
Appreciatively,
Courtney
