Do not drill a hole.
The system is self bleeding once the stat opens for the first time. ie You may see the temp rise to 110C once after refil then a sudden drop to 88C

As a more aged member, I recall that when I had classic cars in the 1970's /80's some of them had black leather radiator muffs fitted, which greatly helped in reducing cold air flow when driving off in the winter with an ice cold engine. Also London Transport even used a sliding steel panel on the RT Type double decker bus that could be risen in cold weather to reduce air flow, as the 1939 AEC engine was also thermally efficient, so there you have it folks, 2 vehicles 60 years difference and technicnically streets apart but one common souoution , Stick a muff on the front, I have and it works a treat!!! |

A radiator blind may help the running temp in certain circumstances but it won't make any difference to the warm up time because there is no coolant flow through the rad during this phase until the stat starts to open.

I can attest to this, having blocked off my upper and lower grilles, with duct tape. Although it did increase the running temp literally by a couple of degrees, it simply wouldnt be worth it.

I cut pieces of corrugated plastic sheet (the type you get pinned to the garden wall advertising the builder when you have had new windows or similar) to shape. These just slot in nicely behind the radiator grille to form an invisible radiator muff, admittedly only covering half the radiator. I used it during the very cold winters we had a few years ago and felt that it did help to keep the engine warm when the heater was running, but it might have been wishful thinking!
