What part of the engine will coolant boil first?
The cylinder head The cylinder head area is the area where coolant will boil first if coolant is present. The area directly above the combustion chamber will get hot first, which is the bottom area of the cylinder head. The old saying that heat rises is still true. Heated coolant will usually exit the upper radiator hose to the radiator and as coolant is cooled in the radiator, it will circulate down into the block where it will be heated again to repeat the cycle. The coolant pump present in most engines just helps this natural cycle.
