Hello again.
I decided to make a new grille block for my Ranger. I grabbed a Splash grille and headlight trims at the pick and pull a couple of years ago. I liked the look better than the stock grille and trim. On the old grille I had installed a piece of clear plexi-glass to make a 100% grille block. It seemed to help and I saw a modest increase in MPG. When the fan clutch locked up it put such a drag on the engine I took off the grille block to let in more air and keep it from over heating. I then found the Splash parts and didn't want put screw holes in the grille so I've left it open for now.
Today I decided to take the old stock grille and start on another 100% grille block. I don't think I'll install it until I get an E-fan set up. Right now, even with the Splash grille, sitting at a fast food drive up makes the temp gauge visibly climb early to red-line. But I wanted to have it ready to put on when the E-fan or winter comes.
I took the old grille and had to modify the mounting because the Splash headlight trims are longer than the stock ones. A Dremel tool, a cut off wheel, and about 15 minutes and it fit nicely. I then took some super sticky "nuclear grade" duct tape and covered it vertically in half-lapped layers from the center out. Then covering it horizontally in half lapped layers added some strength. It's not done yet but I wanted to get it started and get a couple of pics to see what folks here thought.
The final product will be taking the block as it is now and shooting it with spray adhesive and laying a piece of cloth (cheap bed sheet material) on it. Then covering it in the two part fiberglass resin my brother uses on his race car to give it a nice smooth durable shell.
When I had the plexi-glass grille on it there was more than enough fresh air cooling from the small opening under the grille and the other opening in the bumper below the grille (until the fan clutch went out) that when the E-fan goes on I don't expect any overheating problems.
