marysboy Posted February 16, 2010 Share Posted February 16, 2010 Hello all, The thermostat on my Series 3 is open all the time and I need a replacement. I see that there are two versions available: Part number 532453 = 74 degrees C Part number 596225 = 82 degrees C I'm not sure which I should have, does anyone here know? I have a 1977 2.25 diesel. Thanks all, Ian. Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted February 17, 2010 Share Posted February 17, 2010 Go for the 82*, its what i have used all year round for the last 28yrs with no overheating issues even when towing and i dont have a fan cowl fitted. Quote Link to comment Share on other sites More sharing options...

marysboy Posted May 4, 2010 Author Share Posted May 4, 2010 Well I've had my 82deg thermostat in for a couple of months now. Rather than never reaching operating temperature, the engine now heats up in 5 minutes. The heater blows warm air (shock!) and the engine is more lively. The temperature sits just below the red line all the time - will see how summer affects that! Ian. Quote Link to comment Share on other sites More sharing options...

The 74 is mainly for the MoD fleets, and primarily for FFRs that spend a lot of time idling. they use the lower setting so that the flow keeps the temperature from peaking.
