Are you suggesting that it could create a leak when mixed. It's very recent that I added the Autozone coolant to the truck.

 

My guess is that you didn't notice the leak while you were low on coolant, and now that you are topped off you noticed it.

Still no more leaking?

 

Like said above, you probably had a small leak. Mixing the coolants could cause it to change ph and eat the freeze plugs over time. It wouldn't be a fast thing.

 

I'll be back at my truck tomorrow, then I'll see what's up, I might have a small lead. I greatly appreciate all the advice so far.

 

Had it lifted up for some other repairs, and the technician told me there was evidence of a leak from the water pump. As someone here noticed it dripped down on the plate and channeled somewhere else before hitting the ground. Some days it leaks a little, and other times not. Any good suggestions for a water pump or would you always go OEM?

 

I'd go oem
