my 1997 Honda CRV has no leakage that is noticeable. I've noticed that it is overheating could be my thermostat Or radiator cap

What is your question?

I bought a 1997 Honda CRV that has been sitting for 8 months. I just got a oil change and needed a new oil filter. This is my second time driving the vehicle and I have noticed that oily smell coming from the engine. so I looked at my cool and hot and notice that it was hot, overheating. Before I drove today I checked for leaks no leaks even the first time I drove there are no leaks I'm trying to figure out could my radiator cap be bad or thermostat

How long has your 1997 Honda CR-V had this problem?

I just noticed the problem
