got the new hose and finally had some time to work on the car.
Filled with fluid. Car held fluid
Started the car and it idled great with good vacuum and oil pressure. Put pressure cap on. Let the car continue to heat up. Everything going fine. BAM!!! hose blew off the bottom of the AST (rotary performance version).
Anyone know why it wasn't purging air and building up pressure? Should I leave a cap or hose off till it fully warms up?
