Radiator cover TL3473

[Andrew Rowe]

I have a Canadian Mk1 with a ply cover in front of the radiator, TL3473 , original. the Question being, is this to lessen fan noise or is it for carriers in colder climates to restrict airflow? over to you guys.

[Ben]

I believe it's to help in the cold weather. Where the board is stored on each MK of carrier is a debate in itself.

Why can't I find that part number TL3473? Mine is TL853SA???

Ron, the board itself is TL3473 my early parts list doesn't have TL853SA could it be specific to a MK2?

The SA part I think is an sub assembly number. British parts books list a "SA" number then below brake down the assembly into each component part number.

Andrew, It is described as a "Blanking Board".I think it's main purpose is to stop the little sabastians from wrecking the fins of your radiator, when you let them climb in for a look.
Ron, not sure how it all ties up, but the board (as Ben already said ) by it's self was a TL3473.
I think your number refers to an assembly (mid war???) with the 3 rivets holding the dished washer in the board. The later Canadian parts list still lists the TL3473, but says not to demand it, rather order the CTL242A as a complete assembly, which was then replaced by a CO1UC 105115A then a CO1UC 105115B.
I think the difference is in fine detail as they all seem to be interchangeable between all models.

The blanking board was used to cover over tr radiator during cold weather. Same idea as a radiator cover on trucks in tue winter. Helps to get the engine up to running temps quicker.

Does nothing to help lessen the fan noise. Only way to do that is shut the engine off.

As for where it is stored I seem to remember seeing something saying it was stored behind the gunners seat back. It fits really well there and doesn't move around at all.
