No Gavin.
A spacer will move the fan closer to the radiator.
Now I have seen the pic of the phewma shroud,its a bad idea.
The fan will find it easier to draw air from the engine side rather than thru the radiator.Not something to mess with.

I can only see it making any difference if there was a purpose made, shortened shroud to go with the spacer. Then it would at least open up a space between the engine and shroud so the airflow has somewhere to go at highway speeds.
I have considered trimming 10mm or so from the top half of the shroud where it sticks out further than the rest, but the gain would likely be negligible.
My TDCi has endued 50+ degree temps,since when has overheating been an issue?. Pat
Since 2007
Never had any overheating problem with our TDCI 2.4 so I'd leave it alone.
Ford has had a lot of experience with these engines and they are a proven design.
I notice even BAS doesn't require any change to the radiator, only the intercooler, with its 170hp remap, so it must not see engine cooling as a problem.

Interesting thread over on Defender2 about this:
DEFENDER2.NET - View topic - [For Sale] PUMA overheat? We have the cure!
Looking at mine, a 2.2, I can't see any benefit of moving it forward apart from room for more airflow if a shorter shroud was developed. Maybe the 2.4 was the problem?

Here's the thread I referred to earlier about fan / shroud depth spacing.

Totally agree with Jilden's comments about fan tip air dispersement.
The post above looks about right for a fan with no ring around it.
I used to design windsurfing sails, etc so I do have a bit of a clue.

Sounds like BS to me,the highest coolant temp mines ever shown was 96 degree's towing my camper up north,the claims are up to a 15 degree drop in temps which makes mine 8 degree's under the thermostat opening temp :confused:.Sounds like he's designed a band aid solution for a faulty fan or blocked rad.
