I'm in the process of converting my truck to run on veggy oil . I need to tap into the coolant out of the block . Alot use the coolant from the heater core , I see that the heater core line comes out of a tap on the block .
There are a few plugs that are off the block , can I pull one off these plugs and draw coolant from these?
