Hi! 1993 Ford Aerostar, 159415 miles,
I have two problems which may be related: (1) No heat, discovered that vac hose was unattached, did not know where it went so bypassed heater control valve. Do not know where to attach vac hose on engine (2) Was very cold outside, engine would not start, in process of starting, extremely loud bang. Engine eventually starts, but runs extremely rough, finally cuts out, will not restart. Checked, found starter fried, replaced starter, Freeze plug missing directly above starter, assumed all coolant emptied out onto starter. Tried to drive later, would start, but when heated up, would run terrible, and would overheat. When leak was discovered, poured coolant in, WAS coming out immediately below block( via missing freeze plug) which was discovered earlier. Replaced with expansion type plug, drove vehicle approx 4 miles started to overheat. Did not drive.
Noticed coolant leaking again. Now, other side freeze plug gone. Replaced. Started vehicle, let run for approx 15-20, minutes. Overheated to place that it blew freeze plug out. Would not restart immediately afterwards: Vehicle is overheated.
Went out day or two later, started vehicle with no problem, have not been able to drive vehicle.
I have been told to possibly check the temp sensor, thermostat, radiator cap. Radiator and cap is approx 9 -10 months old, thermostat is about 1 year old. What do you think problem is at this point? Any help would surely be appreciated
