to me, th first stat is an engine stat, the controller of the engines temp.
the second one looks like a heating circuit stat, with a bypass to mix the flow. not 100% but i'd be changing the first one. |

Puma has two according to the parts catalogue.
The white bodied one alongside the radiator like the Td5 - PEM100990K And the LR004618 part you've been given, which is in here:  Click image to enlarge 1988 90 Td5 NAS soft top

Thanks Martin! Now which one is likely to cause over heating? I presume the one on the back of the pump will open once the engine reaches temp And the same for the plastic housing type for the heater, that said this one is unlikely to cause any over heating? Just cold heaters?  2016 Range Rover Autobiography 4.4 TDV8

that picture is a transit thermostat housing
NOT A DEFENDER THE HOUSING IS NOT FITTED TO A DEFENDER AND THERE IS ONLY ONE THERMOSTAT the metal bracket shown in the picture that the housing bolts to is the bracket at the top front right of the engine (as you look at front ) where the glow plug wire joint is ON A TRANSIT |

That's fine, but I got it from an LR parts catalogue - traced using the LR part number given.

Much90 as much as i think the same as you the facts are against us!
Land Rover gave this stat, the web shows it for the 2.4 tdci, the work shop manual shows it in the rear of the pump BUT the fitting instructions only show the other plastic assembly? 2016 Range Rover Autobiography 4.4 TDV8 2010 110 XS Utility 2.4TDCI 2010 Range Rover Sport TDV8 (gone) 2007 Discovery HSE TDV6 (gone) 1993 110 csw 200 tdi (gone) 1994 90 HT 300 tdi (gone) 1994 discovery 300tdi (gone) 90 hybrid 3.5 v8 (gone) Range rover bobtail 3.5 v8 (gone) |

see the big wiring loom at the front top of engine , you can see the metal peg sticking out under it by the top hose and cable tie , that's the metal bracket ( number 4 ) shown in martins diagram picture Last edited by munch90 on 18th Jan 2015 5:20pm. Edited 3 times in total |

And that's the exact same diagram that's in my manual also. I started with nothing and still have most of it left! |

Bit off topic. But why are you changing the stat?
I thought you were going to fit new sender Andy |
