I have a 2004 TL Auto transmission. Due to stupidity and not paying attention, I ran the whole car right over a curb. Luckily the only thing that seem to be damaged was some plastic component on the underneath of the car on the front driver side underneath the hood, part number is: 74111-SEP-A03. However, I recently also noticed the the coolant is leaking which leaks on the passenger side. Is it possible to damage the coolant by hitting the bottom of the car and giving it shock? Is it possible to have the radiator damaged? I have a feeling it's more of a hose problem, this guy was quoting me 3-4 hours to diagnose and asking me to pay by the hour...

 

have you gotten under the car to see? "passenger side" is pretty vague. How much is leaking? Have you removed the splash shield to see what's underneath?

Possible that the radiator is damaged but we can only do so much over a forum. If you dont want to spend money on a diagnosis you'll need to take some steps yourself.
