Re: Hot-running LS6
190 on the hiway seems reasonable, but over 210,and you do not hear the fan clutch start locking in and pull the temp back down... i would be looking for a restricted radiator.if the radiator is not dumping heat off to the fan coil then the fan is not going to engage,if the radiator is plugged it wont transfer heat.another thing to watch closely is these systems get alot of air pockets in them whenever the cooling system has been worked on or drained, it is important to work the air out while the engine is idling and the t-stat is open, by pinching off the upper radiator hose on and off for a few minutes, this will help purge the air out of the system [img]/ubbthreads/images/graemlins/beers.gif[/img]
