Has anyone got one of the rear AC in the cubby kits? How do you like it? Worth the $$$?
Any better alternatives out there? |

Cool Air Logan has the kit you're looking for.

Thanks. The pdf below was useful. Does anyone have personal experience? Think I would want to fit an uprated condenser and fan assembly at the same time.

by the flag he is in Canada, which have the 15 year rule, not 25 like US, so yep pumas can get into Canada now. Searching for my first Defender...and started just as Covid hit, so talk about timing.
5 months after starting the search I found it, and here is the details |

Yup, bought my 2009 Puma in Canada last year. Came from a very dry climate, not even a smidge of corrosion. Rode hard and put away wet though. I have spent a small fortune catching up with deferred maintenance and updates: clutch, head micro-cracks, three torsen diffs, bumpers, racks, etc. Love it though. The 110 rear compartment can easily swallow more than one medium sized elephant. And, 30 mpg …unless you are carrying two canoes with the AC on.

Tjhappel however lives in Southern California, he/she seemed to be in more pressing need for proper AC |

You can get a larger condenser which helps. Condenser fans need to be powerful. If a PO has fitted a cheap replacement, that would limit AC temps. Condensers also can age poorly with the fins corroding and falling out. That’s where I would start if your charge level is fine.
My question was about if the rear AC units add cooling ability. If your AC doesn’t blow cold then adding more evaporator capacity will not improve things! |

I was thinking about this just today.
First, about the cool air logan kit. I've heard somewhere that they can adapt them to order, to have front facing vents. Regardless, for me with a small, well insulated double cab, I think the kit could make a huge difference. But in the interim, I think there might be other measures to take. First to block the two central, louvred ports (using a sponge or similar, so the air directs to the adjustable ports. Second to put some ducting insulation around the ducting that goes to those two ports, as the ducting sits very close to the dash/bulkhead and I noticed that it was considerably warmer than the central ducts. So, I suspect the plastic tubing will be heating the cooler air on its way up. Further, have you checked the heater controller valve (inside the engine bay) that it is fully closed? The valve does not always fully close when using just the Hot/Cold dial in the cabin. Check its fully shut and it might improve the cool air you have. Finally, and I have no idea if this is true - so any others with an answer would be great, but I've heard that the compressor can be adjusted, to make it even cooler? Not sure if/how that's possible, but someone might know.  Monsieur Le Grenadier

Has anyone considered adding one of the 12V completely stand alone compressor/evapourator/blower kits that now seem to be available? There are ones for trucks which are packaged in a truck specific white case, but there are also 12V kits that are simply the component parts, ready for you to fit. The evapourator comes in a "kit car" style bolt on blower unit with controls. Seems to come in about £500 from Ebay.... They would draw roughly 50a on full which would make your charge balance borderline if you ran it all the time and the alternator would work very hard, but to get the temp down for half an hour or used with thought - it might just be the boost required. With a big charger you could also run it on "shore power" in a camp site to keep the vehicle cool.

The Defender is a big, leaky, tin shed. You need a fair amount of excess capacity to properly cool it. I have been doing a lot of reading and have found that:
- there is excess compressor capacity, - you can add another evaporator unit as long as it has its own expansion valve, - there are "higher capacity" condensers available. So I'm going to upgrade the condenser but I'm not going to spend a fortune for the stand-alone evaporator unit built into a cubby. Instead, I bought this unit: https://www.southernrods.com/southern-air-...-only.html With some minor finagling, it will fit inside a standard cubby and costs 1/20th of the price. The other issue with the $$$$ unit is that the outlet vents are not positioned very well for doing anything other than cooling the back seat passenger's knees. I'm going to use the Terrafirma storage compartment for the back of cubbies as a duct so I can have the vent outlets higher up and pointed in the right direction. |

That's really interesting. Thanks for sharing. What compressors are you specifically referring to as having excess capacity or is it fairly general?
Is it as simple as fitting a T in the existing Evaporator feed line (somehow) and then you add more gas when you fill? Or how do you then fit this unit? |

Yes, compressed capacity normally exceeds requirements.
And, yes, tee fittings are all you need though they are not commonly available. Charging the system will have to be done by an experienced tech as there are no specs and they will have to charge just using pressure gauges. |
