If you reflect back on post #165, you'll see where I had to change that heater control valve. I was working on the rear frame rails this past weekend, & I noticed a small pool & various drops of coolant on the garage floor after backing out. I popped the hood & started searching. Lo & behold, it's that damn heater control valve again. Before replacing the original, I had read some reviews stating the new one failed. It's just a cheap piece of reproduced plastic anyway. I guess this weekend I'll have to pull this one & take it back to O'reilly Auto.
On a better note, I was able to do some undercoating on the rear frame rails around the areas where I had wire brushed & painted with rust reformer. I only had time to get one coat done, but I plan to do one more once I have another chance. I didn't get pics this time but will be sure to post some next time around.
