My car was running fine all day, ran errands in the morning then stopped for dinner for a few hours then started my car to head home and engine light came on. I connected computer to see what the code was. The code was P0340 so I turned off the code then started to drive home, but I was not sure if I should drive it or not so I decided to park it and get a ride home. Parked it at my boyfriends house for the night and called my friend who has a repair shop and told him what happened and he said he would come pick it up in the morning and check it out. When he went to check it in the morning there was new yellow coolant floating on top of the oil in where you would pour in the oil. So now I think someone put coolant in my oil, because the shop I bought the car from last month put a new radiator and pink coolant in the car. What I am wondering is after a month would there be new yellow coolant floating on top of the oil after removing the cap? Is there something else that could be wrong with my car? Any help is very appreciated.

I purchased the car a month ago from my friend who owes a body shop. A guy had hit a deer with it and it needed a new radiator and hood and headlights. The guy could not afford to fix it so I bought it and had my friend fix it. It was running completely fine this whole time, until the check engine light came on last Sunday. After I checked the code and turned it off the check engine light came right back on so I parked it. It seemed to be chugging a little, but I was not sure because there was a few inches of snow on the roads and they were slippery.

I would drain all the oil and coolant out thoroughly and while it is empty and the plug is out, I would pressure test the cooling system for a long period and see if any coolant runs out of the drain plug to indicate a serious internal issue.
