For the past few months I have been getting a "low coolant" light on. I put new coolant in every couple weeks. When I got the oil changed they said the coolant and oil looked liked it was mixing!
When I turn the car on, for the first 20-30 seconds the car shakes and rattles very bad. What could this be?

Hi there,

First thing to do is get a cooling system pressure test done, this will locate any external coolant leaks, then have a head check done this will check for exhaust gasses in the cooling system, a sure sign of a head or gasket problem, start here.
