1991 Ford Aerostar Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1991 Ford Aerostar

Engine oil leaks are known to develop around the rear crankshaft (main) seal and engine oil pan gasket.

The valve cover gasket may fail, causing engine oil to leak onto the exhaust manifolds.

If you experience poor idle quality and fuel economy (and the Check Engine Light illuminates) after the exhaust system or motor has been removed and replaced, it could be that the oxygen sensor wires are crossed at the rear of the motor. Wiring schematics should be checked to ensure that the correct harness plug is connected to the corresponding sensor.

Chirping clicking noise started at rear of engine about a week ago. 178,000miles on engine. Ford aerostar 3.0.

I loaned out the van; it came back with the side door not being able to open. I've tried locking, unlocking, prying, and removing the top inside panel, but not a budge. How do I get it open before it can even be fixed?

Has been running rough for a while. Happened before and I put it in neutral and pushed it forward then in drive then park and it started right up. Then drove 1,00 miles no problem. Each time after sitting a day or two problem returns.
