1991 Ford Escort Thermostat

  • 1991 FORD ESCORT

I was wondering if anyone out there could tell me where the thermostat is located on a 1.9 litre Ford escort. Is it were they are normally located, because if so, it looks like it is a little more involved than your thermostats on your older cars. If anyone could help, it would be greatly appreciated.
Do you
have the same problem?

Disconnect battery cable and wiring connector from thermo switch in thermostat housing, if equipped.
Remove radiator cap, then attach a hose to drain tube and open draincock. Drain coolant level until its below water outlet connection. Close the draincock.
Loosen upper hose at radiator, then remove water outlet housing retaining bolts. Lift clear of engine and remove thermostat. Do not pry housing off.
Clean outlet housing and cylinder head mating surfaces.
Position thermostat and seat so it will compress gasket. Position outlet to cylinder head, using a new gasket and install retaining bolts.
Connect top hose to radiator and tighten clamp. Ensure that draincock is closed.
Fill cooling system with recommended coolant as follows:
Add 50 percent coolant, then add water until radiator is full. Allow coolant level to settle, then add more coolant until radiator remain full.
Install radiator cap to first notch, connect battery cable and wire connector to thermo switch. Start engine and let idle until upper hose is warm, then carefully remove radiator cap and top off coolant level.
Install cap securely and fill reservoir to FULL COLD mark with proper concentrate. Add water to FULL HOT mark. Check for leaks.
