Thats all. Unless you regularly drive in freezing-cold weather, you'll never 
notice it. Our engine has both the waterpump bypass plugged and the intake 
manifold exhaust-heat passages plugged; warm-up now takes 4 minutes instead of 
three....   I've been running this pump for 18 yrs with no problems other than 
splitting the very thin lower boss used for a thermal switch. And since this 
boss is useless on a Pantera (hose runs into the alternator) & no one even 
remembers what a thermal switch was, I plugged it- and overtightened the pipe plug. 
A welded cap fixed the crack and the hole. FWIW- J Deryke
