radiator design

There must be a good reason for it but I still am wondering why a radiator can't be tilted back at the top.

The reason I am asking is-----------most pickups have square front ends that push a lot of air. If the radiator was tilted back at the top, the pickup could be a lot more aerodynamic. I would think this would improve gas mileage considerably.

I am sure someone who is smarter than I am has a good answer.
 
I think they could be. No one ever thought about it until you right now. Call the white house and tell the president of GM(external_link) your idea. Maybe can get it on the 2011 models.
 
Having the radiator standing straight up is the best way to get the most air to flow thru it, for good cooling. I suppose, if they made a radiator with slanted fins, then they could slant it for lower hood lines and streamlining the styling.
Good idea. get it patented, and you will be on easy street!
 
Dude...it is not about visibility of stuff in the driveway or aerodynamics...it is about manliness, big rig envy, appearance of might. How is it the the some Kenworths can have a relatively small radiator opening and a cowboy version Inter or the Peterbilt has to have huge snouts? I can see having lots of area for slow speed log hauling in mountains or such. Remember the people voted for the Ford F150 (according to Ford) and for years they made an ugly bull nosed design, I've got one.

You know that is something to think about. My wife's car is a wedge sort of shape but the radiator stands straight up but looking at the car from the front it is hard to tell that it is. Shoot the grill area of the car is very small but it does have an area down low that directs air flow. I do seem to remember a car or truck that had a lay back radiator at one time but can not remember what it was. I know things like oil coolers etc have been tried but for the most part have caused other problems
 
Manufacturers spend a lot more time and money on aerodynamics than you think. The blunt front end of most light trucks is a compromise: Slanting the front end necessarily makes the vehicle longer and doesn't necessarily reduce drag. Remember that the idea is to have as much of the air striking the grill go through the radiator as possible; any air that goes around the radiator is lost cooling capacity.
 
Some GM vehicles do have a slanted radiator. You do not have to slant the fins just use a radiator with side tanks and the fins are vertical and work just fine.
