within 10 minutes of picking it up and the dash warning light came on. There was no coolant in the tank, zero. I don't know if the mechanic simply did not fill the coolant chamber or if when replacing the hoses, did not get the connections right. The car is holding coolant now, although I have not driven it again. I will call you if the car begins to lose coolant. Meanwhile, you charged me $18.50 for coolant and I spent another $14.50 at Walgreen's to buy a bottle of it.
