ANTIFREEZE LEAK


Recommended Posts

Posted

:P I HAVE A 1999 SILVERADO 5.3 ENGINE HAD THE PISTONS REPLACED FOR THE COLD PISTON RATTLE. I NOW THINK I HAVE A SMALL ANTIFREEZE LEAK. MY QUESTION IS IT POSSIBLE TO LET THE ENGINE KOOL DOWN OVER NIGHT AND RETORQUE THE INTAKE MANIFOLD DOWN WITH AN INCH POUND TORQUE WRENCH PER THE BOOK PROCEDURE?

WHAT IS THE PROPER TORQUE? I HAVE SEEN SEVERAL DIFFERENT NUMBERS.

THANK YOU
