-Check your coolant level. If coolant is low, that's the problem.

-Watch the fan when the temperature starts to get high. If it doesn't turn on, the fan, switch, or relay is probably at fault.

-Check your oil. If it looks milky, or there's a white/cream colored substance in it, your headgasket is blown.

-Check your coolant for 'oil bubbles' floating in radiator. (ONLY WHEN IT"S COLD - DO NOT OPEN RADIATOR WHEN IT"S WARM) If it has oil bubbles floating in it, your headgasket is shot.

-Check your exhaust smoke - if it's blue, oil in combustion chamber(s) causing high compression (rings or valve seals) - if it's white but overly smokey, it's coolant, and the headgasket is probably to blame.

Could be your thermostat has jammed shut, take it out and check in boiling water.

Radiator core could be clogged with debris, back flush it.

Water pump impellor broken. Remove to inspect.
