One more thought...

The radiator is an Amazon.com Chinese made 4 row all aluminum radiator. I have purchased such China sourced parts for LR’s before. In my experience they perform very well and are built solidly but each time I have installed one they required some effort to fit. Well, this radiator was no different. It was too thick at the bottom. I don’t know what to call them but I had to grind a little off (see photos) and trim the fan cowl/shroud at the bottom on each end, just a little bit.

But... for $244 for an all aluminum 4 core radiator, I can live with a little modification. Yes, I am cheap.

I just added a photo of the amazon listing of the one I purchase. Interesting it has jumped in price by $65 in a few days.

This is very helpful, awesome write up, I am going this route as well. While I would like to have one of the high dollar Aluminum, can't justify that type of expense.

I paid less for the D1 I am working than the cost of the “high end“ radiator. While the radiator I installed required some “adjustments” to fit, it cools fantastically and appears very well built.

I have a 200K mile GEMS 4.0 that's on all its original seals and gaskets. It too stays in the 180 to mid 190's in normal driving conditions but when it's under considerable load it will climb to 210-215. I'm thinking this is it telling me I am due for a HG job.

condx of fan clutch and radiator???

Land Rovers do NOT require head jobs as frequently as the FSM says to disconnect the battery before changing the wiper blades!

This is interesting. The HG in mine was replaced by the PO so I don't believe that's my issue though I understand they could need replacement again at some point. Have you checked your fan? I only ask because I did and it seemed fine. But I've been under the hood quite a bit lately and noticed it spinning longer than I thought it should (or did the first time I checked). I've checked it several more times now and a bit less than half the time it comes to a reasonably quick stop while the rest it spins longer. I'm not familiar with the failure mechanism of these things but I don't like unpredictable mechanical parts. Thinking it has either failed, is failing, or will fail I searched for fan repairs here on Discoweb and there is an interesting thread ongoing right now. I wish it was as easy as ordering a replacement so I could tick that box. I can't see how it would matter but should I be checking the fan while the car is specifically hot or cold? I don't understand why sometimes it seems coupled and sometimes not.

To test your fan clutch, run truck to op temps.

Open bonnet, while peeking through the gap where you can see the fan blades, turn the engine off.

if the fan blades do not come to an immediate stop, call me and I will ship you a new fan clutch (pending my having one in stock, but it’s a good bet I have one)!

With a HD power sucking fan clutch it's better. I also decided to run a toggle switch to my AC fan and toggle it on when i'm climbing a grade that typically push the temps to the low 2's. I recently got back from a trip to SW Colorado and she did fine on all the climbs and was able to keep the temps under 200.

No need for the toggle switch. The A/C switch turns the fans on.

Probably not anymore. It’s been modified

The ecu will not allow the fan to engage until the coolant temps reach 225f. That’s too late, imo. I run a Bluetooth app via my phone that displays the coolant temps at the sensor. A 12” helper fan is only marginally helpful anyway so I figure toggling it on early can only help.

I kept things simple by only running a wire to the fan relay ground post. Fan toggles on/off when needed and has not affected how the ecu communicates afaik.

Highly recommend adding this area to the bucketlist

With apologies to Brian Bonner and Perrone Ford “you are wrong”.

The instant you push the A/C button, the aux fans kick on.

Yes, but if Im on a long slow climb at elevation the last thing I want to do is put additional load on the engine by turning on the AC. Fortunately for me, toggling on the fan was helpful a few weeks ago when summiting all the passes between Silverton, Telluride and Ouray at 12-14K feet.

Disconnect the compressor

When I was in Leadville, I NEEDED the A/C!
