I changed the radiator, the thermostat, and the fan clutch on 84 Chevy and the temperature gauge gets hot!

Question

The temperature gauge goes to 220 degrees and the coiled hoses look ok. What can I do?

Answer 1

try a water pump.  

Answer 2

220 degrees is probably OK if it doesn't blow out coolant.You have a pressure radiator cap so it can run above atmospheric boiling point.

Answer 3

sensor maybe

does it really get hott or does it represent a fake temp

could be alot but check if the temp is real

if it is not most likely your sensor

Answer 4

Does it smoke when you crank the car, or does the oil look creamy like water in the oil, if so the head gasket is probably some thing to look at. The water pump is another part that needs to be looked at to see if it is making the coolant flow fast enough to cool. last it could just be the gauge, but if you smell something funny like antifreeze, or are loosing coolant then it probably is really running hot. If you can't work on it your self, I would take to a shop and ask them to quote you a price on fixing it, they will probably do this for free, You can discuss that at time of quote. this way you know what is wrong and don't have to spend money on the spot. Hope you have good luck.
