I found two 12 mm bolts , one on each side of the metal pipe incoming and out going from the radiator to the engine and back , on the bottom side of the me , towards the front of the Mule those drain the lines only it seems ,and maybe the radiator. But I did find two other 14mm bolts just below the dipstick mounting bolt , one on each side of the block ( one for each cylinder) that drained the coolant from the block . I have a new head gasket and push rods , can coolant get into any other part of the engine oil somehow? The gasket looked good , and I can’t seem to find any cracks , or signs of any gasket failure.
