Rover 416 Thermostat - TK - 421

I have had to replace the thermostat in my 1995 rover 416 (Twin overhead cam, the new body shape). It's a damn fiddly job, and I have just about managed it, but when I separated the housing , the old thermostat fell out before I could check which way round it goes. Any ideas how I sould fit the new unit?

Its on the right hand side of the car, and the unit has a cone shaped actuator on one side and a big spring on the other. Should the spring be facing toward the engine block or toward the wing ?

Ta very much
chris

Am not familiar with this engine, but the heat sensative bulb & return spring are normally on the same side of the stat & should face the source of the heat ie engine.

Spring goes to the engine side. Wiggle pin, if there is one, is usually positioned at the highest point.

Thanks, chaps. I think I have it right... Any ideas how bad it would be if I haven't??? Incedentally, This is absolutely the worst car to work on, the access behind the engine block is SHOCKING!!!

Engine will overheat as the thermostat won't open. The heater will work beautifully though until the engine stops.
