Long story short, i bought a civic half core for my mx3 thought i measure it right, but as you can tell i got the length and the width mixed up. Dont ask how I just did.
Would i be able to turn it on its side? Would it still cool the same or would there be problems with the flow of the coolant.

Any other forseeable problems? Would i run into a problem with the coolant over flow/radiator cap?

 

You may have trouble working the air bubbles out of the 'top'(?) tank of the radiator.

 

there is also a bleed valve near the T-stat housing if u cant get rid of all the bubbles thru the rad cap

 

couldnt you just get a remote mount filler on the upper radiator hose and run a really high pressure cap on the radiator and a lower one on the filler so if it vents off it will be the top one which would go to your expansion tank. Think this would work but i might be wrong.

 

Ive probably already got it sold, but i did figure out what would work, would require some custom work but could be done, to much work for a 130$ radiator.
