How do you cool down a starter?
Though not recommended for long drives, water will help keep your engine cool in a pinch. Add warm water to your radiator, but only after the engine has cooled. Cool water can cause a crack in your engine block due to the extreme change in temperature.
Why does my Car start cold but the starter is hot?
If you have the instrumentation, measure the current draw of the starter while cranking and compare it to specifications. If the current draw is high on cold and hot starts you probably have a dragging armature. If the current draw is okey cold but excessive hot, there must be excessive load caused by the engine.
What happens when you heat up a starter?
Once under-hood heat warms the battery, cables, and starter, a “tipping point” is reached concerning the overall amount of resistance a starter can accept (and still function properly).
What does it mean when Your starter says heat soak?
What exactly is starter “Heat Soak”? Without getting into the physics of thermal conduction or Newton’s law of convective cooling, it is simply a matter of the starter absorbing and retaining heat from under-hood sources such as the exhaust manifold. This absorbed heat adds resistance to the electrical conductors inside the starter.
What to do if your car starts at a high temperature?
Low Starter Voltage. Check by bypassing the solenoid with a heavy duty jumper cable, or by removing the connection from the battery side and touching to the starter side. Replace the solenoid if the engine cranks. It’s not unusual for a starter to “seize” at high temperatures if the internal clearances are excessive.

Why does my car starter not crank when it’s Hot?
If your starter easily cranks a cold engine, but “drags” or cranks very slowly when hot, there may be a “heat soak” problem. Before you condemn the starter as bad, you should perform a system diagnosis of the battery, cables and starter.
Why does my Car start slow and get hot?
Hope that helps. The slow cranking is from bad bearings in the starter. The heat is from the electrical resistance of the (extremely powerful) starter motor trying to turn against the high resistance. The high battery drain is from the high current draw of the starter trying to turn. Thank you all for your answers.
