(clipped from previous response)<<(shrug) I'm not paying another fortune to fix this problem if the head is cracked, and no coolant is entering the engine chamber. I'll simply continue to just add coolant at this late stage of this car's life. >>
1990 model, 195K miles is late stage of the car's life??!!
Check out Larry's signature. This car is just broken in!! You've got another 150k to go on this one! Check out the sale price of a replacement car, comparable to this one. That may sway you to repair it.
Good luck, with whatever you decide.
