I use my landy for daily commuting (few kilometers between home and work) so in October I put on the radiator muff and it stay in place until springtime. The photo below was taken in the Italian Alps last winter, just after a long trip from Paris (so the muff was rolled).

That's exactly the sort of thing I was rattling on about earlier in this thread except the 'period' ones I was referring to brought the blind control up into the dashboard - or underneath it. The muff was on a sprung loaded roller type blind affair mounted in front of and at the bottom of the rad, a Bowden cable was fitted to the blind which ran through the engine compartment and bulkhead and terminated in a length of chain and a ring. To raise the blind you just pulled the ring and then locked it in position by hooking the chain over a peg under the dash. More Series 1 than Puma but the ones I'm on about were on pre 1939 cars with tall rads, no water pumps and thermo syphon cooling. Steve.

Today I have done just over 350 miles with the card in front of the radiator. Left early this morning heading for Warrington my first stop. By the time I got to Sandbach services I was a bit worried that because the outside temperatures had risen it might have been getting a little too hot, so I pulled over and trimmed the card from ¾ covered to ½ covered. The first 25 miles of the 350 have been done over the last few days just going back and forth to work all cold starts and short journeys. I would expect to get around 19 to 22 mpg for this. As I wrote earlier in the thread I did 182 miles on Saturday travelling at 60-65 and got 26.3 mpg. Today I travelled at about the same speed and filled up before I got home. It recorded 27.9 mpg so that is and small improvement but whether it is down to the radiator being semi covered is another question. Also it should be noted that I have 285’s on the vehicle so logically is recording less miles on the clock than it would had I been running on 235’s.
Both mileages were recorded on BP fuel. |

I'm beginning to theorise that using a full muff restricts the intercooler, reduces power and thereby improves fuel consumption. As I mentioned yesterday, my full muff stopped me going as fast as I would normally - is that possible? Tell someone you love them today because life is short.

Indeed you maybe right. Mine was running spot on today (as the intercooler was not covered just the rad).

Oh - just found a pic of rad and intercooler - so the intercooler is just a rectangular unit behind the right hand third of the rad (behind the Land Rover badge)? Thought it went underneath too

ZeDefender,
i am afraid you are looking at an oil-cooler or something (intercooler runs horizontal, oil coolers vertical on one side of radiator) look here in the pictures both standard and performance intercooler pictured: http://www.defender2.net/forum/post60440.html If you have airco the airco-cooler is hiding your intercooler. regarding the muff, ideally you would put a sheet between radiator and intercooler but the frame has no slot as far as i can see on mine. Need a solution also so if i find something iĺl tune in.  |

Many thanks Yehaa - understand now: in order from front to back: full-grill-size aircon cooler - smaller intercooler - radiator
So having the muff done up kills the intercooler entirely - if the effect on power is that I can't go above 130 km/h, I understand why people harp on about intercoolers so much  Tell someone you love them today because life is short.

you are correct, Huge aircon exchanger - intercooler - huge radiator front to back
you will have an electric fan attached to the airco rad. The airco rad is the thinnest of the 3. Another benefit sometimes forgotten about the muffs is that they prevent the radiators being clogged with snow/ice. As long as there was only the cooling radiator that was not such a problem as the engine heat would melt this away but with the airco rad in front and the intercooler sandwiched between them you risk blocking all airflow in heavy snow. (and the visco fan is sucking in air, so you have a bumper snow-vacuum cleaner in the morning at startup) Seen this on other cars with much less frontal shapes. funny to have an engine overheating at minus temps. |

The Exmoor trim one only takes a minute or two to put on and take off which means it is a lot easier to nick than one held on with cable ties. It is secured on the top two corners by a strip of fabric at a 45 degree angle which slides behind the radiator front grill and is held on at the bottom by two adjustable clips which attach to the bottom slat on the grill. I have yet to have it closed completely as in the standard open position shown the scangauge shows CHT temp at a constant 70 degrees when sitting at idle for long periods on a cold day which is enough for the heater to still be blowing hot air instead of the normal cold air after 5 mins.
