If you don't mind a non-diesel question.





Changed my 4.3 S10's coolant yesterday. Reloaded it with Dex Cool. Since air is the killer of this product how do I know if I got all the air out of the system?? I understand the 4.3 is a problem with this coolant and I drained perfectly clean coolant out and would hate to have no started a problem.


There seems to be a "plug" on the engine just BELOW the spot that the hose from the radiator attaches. Is this a bleeder?? Looks like you would lose a lot of coolant if you opened it.


Unfortunatley I don't have a Service Manual for this truck, just a Haynes that says to refill the system.

Thanks





Just keep check on the tank or actually remove the cap and check it??


Why is there such a big deal about this engine getting air in it?? Operator error??
