now my STS has it :( at 67500 mls... very bad so early! well is there something wrong with the engine? I heard the 99 engine wasn´t build perfect GM made a mistake I heard. is that true? so if I reapair the HG does it come again?? Whats the reason for the broken HG?? What kind of coolant should i use? only the Dexcool or an other one which is also allowed?
How about the waterpump? does it also brake down soon after the HG? are the pellets important to do it into the new coolant??

THX a alot
