I have 86 TA with a 5.7 ... new water pump last fall, termstat last week, wired fan direct, new coolant sensor's ... but i still get code 15... and over heats up to 260 yest.... drained the rad and pull the engine block plug... I did a reverse flush and water came out throught the resoiver tube.... I can pinch the top rad hose and coolant will spit out of the tee I put in the heater core hose...
any ideas why this is not getting coolant to the engine block???
