I bought this truck about 6 months ago it ran great for awhile. I've put 15,000 miles on it so far but it started to show symptoms of overheating then it started overheating. Changed the thermostat then it overheated again. Took thermostat out in belief it got vacuum locked. With air in the system. Changed the A/C compressor. Then thermostat was stuck. Originally that's how the overheating started. Now it drives sluggish at times and feels like its bucking. It now will not keep coolant. Then check engine light been on. The ABS light. When I back up it sounds and I could feel a loud clunk. I'm not mechanical so my person is doing. This diy and don't have have money storage to a shop.

Hello, I'm Danny.

The first thing you will need to do is have the codes from the check engine light and abs scanner so we know what the codes are to properly diagnose these issues. Here are a few tutorials for you to view showing how diagnostic codes are retrieved:
