how essential is the coolant crossover tube for the temp of the heads? i kinked the line a lil bit on the end where the hose slips on the steel tube, the one that goes into the radiator. how much will this effect my cooling?

 

as long as water can get through it will be ok, take a cresent wrench and round it back out......

 

if it get stopped up or badly kinked, what happens?

 

It's a steam vent. If it's completely blocked, guess.

 

lol, gotcha
