Any suggestions for covering the radiator to keep engine temps higher in the winter? My concern is the other coolers that are up front (transmission, etc). Unless pulling a hill I run about 170 and that's in moderate outside temps. When go east ill be in single didget temps.

 

Sounds like a thermostat is the real issue. I have been putting cardboard in front of my rad for 3 winters now, and it hasn't been a problem at all. When it get at about 25*F, I have to uncover about a quarter of the rad to let air flow though. Otherwise, it's nice and warm, but not hot.

 

times 2 on the cardboard i have been putting it in my little jeep diesel for the last 3 winters and i have never had a problem either. just make sure you use like a beer box or something so when it gets wet it doesnt turn to mush.

 

Good reason to drink beer plexiglass works good too

 

just use cardboard and cut a 5 inch diameter whole in the middle for air to got through

 

I know it's an old post, but I use one of those white foam boards from staples. The width is exactly snug...just slide it down between the front of the radiator and the I/C and trim the top off with a razor knife.

 

I do the same as rockin with the hole and then just cover 3/4 of my radiator

 

would be best to attach your cardboard or plexiglass/lexan to the back of the grille so air can still be pulled through the radiator if necessary.

blocking it off completely like that with no air gap can cause a serious overheat issue when towing. also just cutting a hole infront of the clutch fan can prevent the clutch fan from ever engaging.

 

I put my cardboard out by the grill over everything and dont cover all of it. the main purpose for the hole is to keep from pulling the fan through the radiator. Dad said years ago he saw a couple guys who thought it would work good until they sucked the fan right into the rad because of the suction.

 

see just bolt or zip tie to the back of the grille and eliminate both issues
