A great way to flush your cooling system is too not put the lower hose on well enough. At about 70 on the interstate, with cardboard over the radiator, the hose will blow off and form a huge cloud behind your truck.

Moral of the story is, the clamps that come to hold on the hose are horrible. I have change mine out. Learn from my mistake.

 

Yea and if you ever push the upper rad hose on a 2nd gen in front og the oil fill tube be sure to move it back before you go to town. None of the auto parts stores in my town stock them. They said they could get one the next day. Thats when I pointed out the big puddle under the truck.

 

Well you discovered the smoke screen secret, that is how the security guys lay down one, squirt some anti freeze into the exhaust.

 

Actually they use Oil, but I guess antifreeze might work at night.
