winter front

Does anyone make a winter front to block off part of the radiator over the winter. My temp is perfect all summer long but could be alittle higher during cold winter months. Before I make something just seeing if there is anything else out there.

They used to, many years ago, but I haven’t seen mention of them in a long time.
Most Bronco owners that experience odd cooling issues, typically have the opposite to deal with. Runs too hot in the first place!
Quite a few people have made things over the years, but I don’t know if anyone commercially makes what you’re talking about anymore.
Be interesting to find out. Glad you asked the question!

I actually was thinking about that for my 68 also. After installing the WH triple pass Radiator, it runs cool all the time. Even takes a while to warm up in the summer
But I figured I would check the thermostat first, before going down the fabrication road.

I always just stuffed part of a cardboard box in front of the radiator back in the day. Lately I use a factory Ford 90s mustang thermostat. Sealed shut until it hits the 192 and holds that temp way better than any of the aftermarket units.

When I lived in Idaho, I used a piece of corrugated plastic (think cardboard box) and had a piece that I dropped down in front of the radiator and suspended from the upper mounts. It didn't go but about 1/2 way down. Also kept the snow dust from accumulating on the distributor and carb to freeze up. Ran it about 5 months out of the year.

you could buy sheets of plastic, aluminum from Amazon and zip tie those in place?

I would say a properly positioned 30 pack carton from your favorite beer would be a nice and functional touch. Just be sure you install it neatly with care. Otherwise it might wind up looking haphazard and trashy

I used a piece of cardboard for years in my courier. Works like a charm. And it was super easy to store behind the seat to install or remove as needed.

Maybe there is a truck with a similar size grill as your CB. Here a link to a company that makes winter grill covers.

I got some 3/16 aluminum plate laying around. Gonna do a quick finish on it and bolt it up. Gonna start with blocking a third of it and go from there. Will post some pics this weekend after I get them in. Temp falls off hard next week so should be a good test.

Why not use cardboard? Using it was the ONLY way to bring my 351W temp up towards the tstat from Nov 1 to April every year.

I got inspired once and painted it and felt like I should take it to a car show! lol So I still paint it every year and it just disappears behind the grill.

Fold 2" of the cardboard over at the top so it can lay over the top of the radiator core so it won't slip down. Won't move all winter then. I wouldn't use anthing that could wear a hole into the beer can thin alum AND because you don't need to because unless you mount it directly against your core (or within a 1/2") the fan will pull whatever air it needs around any air dam that is more than an inch away from the core. Simply put, anything on the grill won't help.
