3mirrors Engine Coolant Pipe O-Ring Kit Fits Ford F-150 926-168 – OE Solutions DR-3Z8566-A BC3Z-8590-F

Saved me a lots of money I had an anti-freeze leak and brought it to my mechanic to find the source. I usually do all my mechanical work myself but couldnt find where the leak was coming from. He told me to bring it to Ford and see if the block was cracked. I wasnt prepared to leave my truck at the dealership because I need my truck for work. Anyway, one morning I saw a HUGE puddle of anti-freeze in my driveway. More then I ever seen before. I popped the hood and found a puddle of fluid sitting on part of the frame and the plastic shield. I thought for sure it was my water pump but couldnt confirm. I took a rag and cleaned as much as possible to see where the leak was coming from. I then ran my hand near the thermostat housing and there was liquid on my hand. I then took my iPhone and recorded a video and noticed that their was a drip around the thermostat housing. I then cleaned the housing dry and waited a few minutes. Ran my hand and sure enough, it was wet. I cleaned it again and touched the bolts seeing that the fluid was dripping from there and they were dry to the touch. I then ran my hand on the hoses at the TEE and sure enough, there was the leak. I ordered the O-Ring kit, arrived the next day and VOILA, no more leak! One thing that upsets me the most is that there are hundreds of senors on new cars but they cant detect a leak. Go figure!
