im loosing coolant. no puddles or anything its almost like its evaporating to fast... any ideas

 

check you hoses my fan sliced mine one day and lost coolant fast check that the hose is conected to the resivior

 

a bad head gasket will leek coolant into the oil galleys or be burnt in the compression chamber
check the oil for milky color

 

If it's not leaving as liquid from a leak, it is leaving as vapor from the exhaust as in blown head gasket.

 

X 2. If you're not leaking coolant, you're bruning it. Only 2 ways to lose coolant.

 

so how much work is a head gasket? cost? time? i need to know if i need to take off work to get it dont and other than just putting more coolent in can it really hurt my engine if i wait till it warms up out side to perform the surgery? sorry for the flood of questions and thanks for the help guys.

 

have the cooling system pressure tested by someone who knows their way around a car before you go doing anything serious.

 

i am having the same problem pressure tested it and found no leaks i am also getting black tar like string in my coolant

 

A 2001 eh? Do you have the "0331" head that sometimes develops a crack?

 

If you have an 00 or an 01 and you have "unexplained coolant loss", the odds are quite high that you have a cracked cylinder head.

There is a known casting defect between cylinders 3-4 on that head. And the #1 symptom of a cracked 0331 head is unexplained coolant loss.

So if you have performed a comprehensive search for a leak and have found none, you likely have a cracked head and you need to educate yourself about it and do it fast. Coolant mixing with oil will toast your engine bearings and wait long enough and you'll need a rebuild or a different engine.

Instead of reinventing the wheel, read this thread.

sell it quick

 

Note to self: Never ever buy anything from Firestorm. I mean ever...

As for the OP, welcome to the cracked 0331 head club...
Takes about a day to take the old head off, three days to get a new head from Clearwater and another day to button it all up. Total cost including replacing all gaskets and the cooling components (except radiator) ~ $700.

 

Actually, I've been a victim more times than I can count of the "sell it quick" club.
