LR032135AL is the aluminum thermostat and housing for the 5.0 liter AJ133 V8, and it goes in place of the plastic assembly that Land Rover catalogues as LR032135. That is the whole point of this part. Same fitment, same job, same number behind it, in metal instead of plastic. The housing carries the thermostat and forms the coolant junction at the cylinder head, which means it lives under constant heat cycling with coolant pressure behind it and hose clamps and fasteners pulling on it. Aluminum takes that and keeps its shape. Plastic is asked to do the same job for the life of the engine, and it is the part of this assembly that owners end up thinking about. Going to aluminum is the kind of upgrade you do once and stop worrying about. One housing covers a lot of ground. Land Rover catalogues this assembly across the Range Rover L322 and L405, the Range Rover Sport L320 and L494, the LR4 L319, the Range Rover Velar L560 and the Defender L663, on both the supercharged and the naturally aspirated versions of the 5.0 liter V8. The one thing worth checking is the LR4 L319, which Land Rover only catalogues with the naturally aspirated engine. The factory number has moved more than once over the life of this engine. LR032135 is the current one, and it supersedes LR029143, LR023429, LR010799 and LR010796. That matters if you are working from an older parts list, because LR029143 was catalogued as a water outlet connection rather than a thermostat and housing, so the same position on the engine can turn up under two different names. Frequently Asked Questions How is this different from the standard LR032135? Material. This one is aluminum, where the standard assembly is plastic. It covers the same Land Rover part number and the same vehicles, so it is a direct replacement rather than a modification. Does this fit the supercharged 5.0 or the naturally aspirated 5.0? Both. Land Rover catalogues this housing against the supercharged and the naturally aspirated 5.0 liter AJ133 V
