<div>I agree with that point.  When I had my engine out of the car and 
striped to rebuild it I opened up the expansion plugs and used a high pressure 
hose to wash out the water channels.  There was about 2 inches of mud like 
crud at the bottom of the water jacket inside the block. It was shocking to see 
what spilled out on my driveway.  After the rebuild I haven’t had any 
problems with over heating. Everything else on the car is standard except for an 
after market plastic fan.</div>
