When I pull out of the garage in the morning, I can see coolant on the garage floor ( pass. side front of truck).Crawled underneath yesterday to see if I could see where it is coming from. No luck there, although the drops are coming off the front corner of the block on the pass. side. In looking from the top, I see evidence of coolant around the water pump housing, but it is dry, with a shiny glaze over it. So I'm thinking loose bolts on the pump. Not so, says the wrench on the bolts. Basing this statement on the hoops I had to jump through yesterday to get to the bottom bolt. The water pump is going to be a SOB to change, unless I'm missing something obvious. I know the belt has to be undone, which I didn't do yesterday. What else is there, to be removed? Alternator?Anything else you can thing of that would drip coolant from that area? New radiator hoses a couple of months ago. No signs of leakage on the lower coming out of the block.
