engine very hot might need coolant?

[Milio Marsh]

my engine gets very very hot, I look in the radiator and its all filled up with radiator fluid I was wondering instead I might need coolant were does that go? theres a small little tank on the left side of the motor that says "Radiator coolant only" and its empty. If I buy coolant and fill it up do you think that my problem is solved?

Thanks

Fill that up to the cold fill line when the motor is cold. Then drive for 5-10 miles and check the level. It should be at the "hot" level. If it's not, add a bit more.

If that doesn't fix your problem then it could be your thermostat or radiator cap or something else.
