Head Gaskets, coolant flow or no-flow
Posted by Brian A. On 2013/5/23 15:17:46
Hello everybody,
While I was getting ready to put the heads back on the block I checked the head gaskets to make sure they were correct and they aren't, or are they? On the block and head there are three passages for coolant flow from block to head. They are located at the bottom, a large round passage in the middle and two triangular passages between the outer and inner cylinders. The gasket I removed, a steel gasket, had openings to allow coolant flow at these three passages. The new, composite, gasket does not. In the Service Manual, Engine chapter, page 4, figure 11 shows coolant flowing through these passages. Page 22, figure 51 shows a picture of a head gasket without openings at the three points. Which is correct, flow or no-flow?
