[QUOTE="swampratt, post: 2843700, member: 15054"] Do not run tap water through it. Pull the lower hose and drain then you can get crafty with a shop vacuum that is blowing and blow the coolant out of the block through the upper hose if the thermostat is removed. I agree with going Green .. That dexcool (Orange) is great stuff until you get any air in the system then you are screwed as it will quickly make rust. I change coolant in all my vehicles at least every 2 years.. some vehicles get a summer mix and a different winter mix (hot rods). Keep all oils off the hoses.. never apply WD40 to rubber products as it will degrade them. Wife's 95 corolla still has all original hoses and they look and feel good as new. 280,000 miles on it. Power wash engine at every oil change and to avoid the transmission flushes I pull the trans drain plug every other oil change (6000 miles drain trans). It only drains 3 quarts.. I like to pull spark plugs at 20,000 miles or sooner and inspect. If people would do this in the ford Mod engine the plugs would not get stuck. I feel 100,000 is a long time for a plug to be twisted into the hole.. The plug may be fine .. Heck i never replaced the Motorcraft plugs in my 79 mustang inline 6. But i did pull and clean them often.. that car went 376,000 miles and the Fox body just fell apart around the engine and trans. [/QUOTE]
