Two days ago, I had antifreeze put in my car. Yesterday, I noticed a little smoke from the hood while at a light. I pulled over and opened the hood to see a dripping from the cap where the antifreeze could be put in. Not the coolant tank, but that other area that should not be opened while the car is hot. I just figured it was too much poured in and the excess was dripping out. The car was not running hot at that time. My car overheated while driving about 3 AM this morning and then came to a slow coas, then shut off. I had to have it towed home. Today, I opened my hood and saw that the hose had came off the radiator and antifreeze was all over the place. I put the hose back on and added antifreeze. The hose looks a little burned. I tried to start the car today. It cranked like it wanted to start the first 2 times, then it didn't turn over any more. Just 1 quick crank and nothing. Is it possible I did something to the engine since I drove it while it was overheating? The car has a new trans, new alternator, new battery, I hate to think I need another engine. This is my 2nd Lexus and it seems like it is the same pattern. First trans goes....next overheating....then new engine! Help :(
