I have seen reference to ‘hot climate’ or ‘Gulf spec’ (vs. RoW) markets for JLR where they use additional radiators, more powerful fans, lower temp thermostats etc.

I’ve not been able to find detailed information on exactly what’s involved…is there a ‘hot climate’ version of the F-Type? If so, which markets get it, what are the differences and can any useful cooling system enhancements be retrofitted to RoW models?

 

I know what you're referencing as I've seen this on JLR TOPix. Its stronger radiator fans. The upgraded units are 750 watt while the standard is 500 watt.

 

All I know for sure is that the XFR had a hot climate version in some markets and that involved (at least) an extra auxiliary radiator behind the front left corner of the front bumper cover, to match the standard auxiliary radiator behind the front right corner. Funny thing was my 2010 Aus delivery (ROW) XFR did not have this hot climate set-up (ie no extra radiator) despite some parts of Oz including where I live in Adelaide getting as hot as anywhere else on the planet including Phoenix, sometimes hitting 45 C (113 F).
Dunno about the F-Type but I don't recall ever reading about a hot climate version.

Edit - should read my own doc better - my copy of the 2014 V6 Workshop Manual clearly shows a hot climate version of the coolant system, with an auxiliary radiator, see items 4 and 5 in the attached PDF. This auxiliary radiator is mounted to the bottom front of the main engine radiator and pokes out/sits horizontally rather than vertically. It doesn't look like there is anything else extra to the hot climate version. That said and based on my experience with my my old XFR, who knows what markets got this hot climate set up and which did not, I don't think my F-Type has it but I'm not sure.

 

Thanks. It seems at least the more powerful fan at least would be easy to retrofit. I thought I had a horizontal radiator in front but maybe not, I'll have to go take a look. You'd think more companies would angle to serve 'hot climate' packages. I realize resistive heater wire is cheap, but what the hell is someone going to do with a heated steering wheel and seats in Phoenix? or Adelaide, or LA or Miami?

 

Yep, my F-Type has a heated steering wheel (and heated seats) and I have never used either of them!

 

I've used them both frequently in mine, but rarely use the cooling function. I guess you could use that!

 

It seems the V6 and V8 cooling system components are pretty much the same, so the V6 cooling system would be relatively oversized.

 

V8 has larger oil cooler

 

My 2018 (MY19) R-Dynamic P380 came with the additional lower radiator and uprated cooling fan. I have no idea why a UK (not what you would perceive as a 'hot climate'), V6 car would come with this system from factory. It seems way too much in terms of cooling capability given the lower thermal energy load compared to a 500- 575bhp V8?

Possibly Jaguar rationalised the assembly of the 'radiatior pack' at some point, consolidating variants to just produce the 'hot climate' version. I have seen a radiator pack for a P300 (i4 engine) online from a breaker, which also included the additional radiator. This would be even greater cooling capacity overkill given the smaller design/lower output of the inline 4.

The additional cooling components and uprated fan must have come at a cost to Jaguar, so it does seem odd they fitted the 'hot climate' system to cars that were highly unlikely to require it for reliability puposes .

Strange decision by Jaguar (but not the only one )
