Next, I went and blocked off 2 of the grille slats. I blocked these because the intake is on the drivers side one, and I wanted to keep cold air from reaching that part of the bay, the other was to keep it symmetrical. I didn't have the time to block off the whole thing, so I just did those two.
This helped more than I originally thought it would, and I saw a rise in coolant temp once warmed up. Warm up time wasn't effected much, mostly cause the bottom one did more area.
Keep in mind, that I did these blocks this way to try and keep it looking stock. I didn't want a grille covered in duct tape. So I used duct tape at any time It would go with the color it's going to be on.
While driving a Jeep and/or truck, it sometimes seems as if the side of the road is more interesting than the road it's self. It often leads to VERY minor dustyness, and yellow rims. Many Jeepers don't wash their jeeps, but in fear of rust and paint removal, I washed it up. This was also in hopes that the grille block would last a little longer. This next pic is of when I first made the block. As you can see, it's not as weather torn.
That dustyness is nothing compared to what most Jeeps and trucks that are used properly go through, but salt had been building on there for a while, and it was the only warm day I could get until the weather dropped below freezing again the next day. Here's what it should look like after washing.
As you can see, washing, if done properly, does not effect the grille block. So for those considering the water and etc. Nothing should happen to it from washing if washed properly.
Waiting for some upper grille action? that's what's next.
