Why is my pickup overheating?
Why Do Engines Overheat? Engines can overheat for many reasons. In general, it’s because something’s wrong within the cooling system and heat isn’t able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.

A broken thermostat might be stuck in the closed position, causing the engine to warm up – and then keep going. No matter how hot the engine gets, the coolant is unable to pass through. This is a real problem and can cause your engine to overheat rapidly.
What to do if your Toyota radiator is overheating?

If you’re only overheating on the highway, you might just replace the thermostat (especially if you’re driving an older vehicle).
