What is your question?
would high coolant temp and low oil pressure be indicative of an oil cooler failure or head gasket? 4.3 litre eng runs strong, only blows oil at startup and doesn't pysically overheat, even though coolaqnt temp sensor is maxing out. Is same vehicle that has 286,000 miles on it. trying to "nurse" it til we caqn afford an eng rebuild. thx...

Do you see oil in the coolant? If you take a look inside the coolant reservoir or the radiator, is oil present? This is usually a sign of a failed oil cooler. At the early state of the failure usually won't cause overheating, but it certainly will overheat later. Bad temp. sender unit could show false reading also. Zee
