Hey guys, I overheated the other day cause I had no coolant in the radiator. I'm as green as they come lol. I burped the radiator, but the truck still overheats in idle. What's my next move? Replace water pump ? Please help!!

 

I would suspect the thermostatic fan clutch on the fan behind your radiator first thing if it overheats at idle.

I assume your truck is equipped with one of these. Can you turn the fan when the engine is shut off?

 

Yeah I can turn the fan manually with engine off.

 

So, why was there no coolant in the radiator?

Like 88xlt states, check the fan operation

You should be able to pull a heater hose to check the water pump flow.

What year is your truck?
