tool time

Today was another busy day.  My dad and I went to Baltimore to pick up a car part and I spent the rest of the day at the mechanic's shop.  I got the turn signal casing but on, recharged the ac and flushed the antifreeze.  FYI- I know that car places tell you to change the antifreeze and it seems like a scam but you really should do it.  After a while the antifreeze breaks down and becomes corrosive.  This can cause major engine problems.  Been there, done that.  I think this is one of those well kept car secrets.  Today I learned that there are several different colors of antifreeze and you should NOT mix them.  There are some that say for use with all colors so that one is fine to mix but not the others.  Antifreeze colors include: red, blue, yellow, green, orange and purple.  Could be a few more that I forgot.  The have different additives that react with different metals (that the engine is made of).  That's why you shouldn't randomly mix them.
