I have a 1985 300SD with a starter that won't crank while hot after long drive, only solenoid click. If I wait 5 to 10 minutes it will start without issue as it does when cold. Is this a common issue with this starter or is this a sign of more issues to come? I read that wrapping the starter with high-temperature insulation could help keep it seizing from the heat. Does anyone have experience with this that they could share? Thanks..
