Here's the thing the car seems like its okay but coolent isn't circulating. The radiator never gets hot but the guage does. Can't really drive the car because it overheats within five minutes. Any ideas. Its an 84 944 with about 130k miles.

Bleeding air out of the cooling system in a 944 is a little tricky and an air lock could be the problem. Do you get heat in the car? If so, your water pump and thermostat are working properly, and the most likely problem is a clogged radiator. If you don't get heat in the car, the most likely problem is a bad thermostat and the next likely is a bad water pump.
You will have to remove the timing belt to replace the water pump, so you might as well figure on a new timing belt if the water pump is the culprit. Otherwise, a thermostat replacement is not too difficult and can be done from the top of the engine.
The thing to worry about is whether the engine has overheated and damaged the cylinder head. As long as it runs smoothly before overheating, you're probably still okay.

You can test the water pump by turning on the heater in the car full blast, if it gets hot, its usually not the water pump. If you have cool air coming out then your water pump is probably gone. And I do feel for you, they are not cheap on a 944.
Could be a thermostat or clogged hose or a hose that is leaking between the res. and radiator, anything on the ground when pouring coolant in?

Tricky one but i would guess either a blockage in the system somewhere caused by an air lock or gunk,or your head gasket could possibly have gone.Get a mechanic to have a look at it if you arent mechanically minded otherwise go through the system yourself,maybe removing rad and flushing it.Whilst rad is off try running water through the engine too,see if anything happens.Other possible causes are a knackered water pump or thermostat

you may try the water pump by utilising turning on the heater contained in the motor vehicle finished blast, if it gets warm, its generally no longer the water pump. in case you have cool air popping out then your water pump is in all probability long previous. and that i do sense for you, they are not low-fee on a 944. may well be a thermostat or clogged hose or a hose this is leaking between the res. and radiator, something on the floor whilst pouring coolant in?

sounds like the thermostat is not opening or you have a problem with the water pump also check that nothing is preventing air air flow through the radiator

Check/replace the engine thermostat. It could prevent water circulation if its bad.

Sounds like the thermostat, should be quite cheap. If not, it could be the water pump, could be quite expensive. Take it to a garage and have them check it.

you have an air lock in the radiator. Probably caused by a failing head gasket or a crack in the head/main engine block. OR.... a knackered water pump....

Sounds like a stuck thermostat.
