About once each summer on a hot day, my Cadillac Catera won’t restart until it cools for 15-20 minutes. I turn the key and the dash idiot lights come on but the starter does nothing. It only happens rarely and only on a hot day. Any ideas ?
More than likely the starter is starting to heat soak.
Heat soaking is where an electric motor ( which a starter is) is effected by heat where it’s mechanical and electrical components fail. You allow that electrcal motor cool down and it functions again.
This is usually remedied by replacing the starter. Unfortunately, the starter in your vehicle is located under the intake manifold.
