How do you drain the radiator in the 1994 sunbird, v-6. The drain turns but the water doesn,t drain out.

According to autozone.com,
The Radiator Cooling Fan Motor Relayis located: Under hood, driver side, front engine area, rear side of battery, mounted on fenderwell

Unplug the coolant fan & put battery voltage, directly to it

If it works, in either direction, then get a wiring diagram
& work on testing the control side of the circuit

You can check all fuses, but replacing a blown fuse,
is not a fix, for anything, that caused it to fail

change thermostat and radiator pressure cap and good coolant liquid
hope it help

You can put the thermostat in a pot of water on the stove
& put a thermometer in there to test,to learn something,
that's a good idea

Your still going to install a new one every 6 to 8 years

You don't have to drain much to remove it from the car

rad cap wont hold pressure- replace

Try to replace your thermostat check see if your fans are working properly and if you can see if your water pump is also working.

1-2-3-4 clockwise rotation for the 4 banger. 6 cyl's 1-2-3-4-5-6 (one is above 2, 3 above 4 ect from left to right.

You will need to pull the dash assembly away from the firewall slightly and remove duct work from heater case on right (passenger)side then the heater core cover,the 2 bands that secure heater core,drain cooling system,remove the 2hoses,and swop out old heater core.

if you replaced the relay because it melted that means there was a short in that circuit. if the water pump is circulating the coolant properly then there is either a faulty temp sending unit on the intake manifold. a faulty sensor on the fan itself, or there is a blockage in the system. if all of these are ok then that means that you have a air bubble in the system. to correct this start the engine with the radiator cap off turn your heater on to high fan high heat and run the system. when the engine reaches temp the upper radiator hose should get real hot ,if it doesn't then the thermostat did not open. replace the thermostat. if it gets hot then let the engine run for a bit top off the coolant shut vehicle down and replace radiator cap this should solve the problem

Hi,

Depends on what engine is there inside.
1. for the 2.0 4 cylinders, 1-3-4-2;
2. for the 3.4 V6, 1-2-3-4-5-6

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
