Over Heating Issues!!!

[tammha]

I replaced my radiator hoses , new thermostat, and new radiator.
Now my temperature guage is on high , What could be causing this to happen? Everything worked fine before i changed everything. I would appreciate it if any one has any ideas that could be causing this.

:bash:

Make sure the radiator is hot to the touch when the car is warmed up. This will let you know that the thermostat is opening and coolant is flowing through the radiator.

You can also remove the rad cap when the car is cold and let it idle until it warms up. You should see the coolant flowing when the thermostat opens.

Check the radiator hoses to make sure they're not collapsing and restricting the flow when the thermostat is open.

You have an air pocket behind the thermostat.

Bleeding the KA coolant system sucks.

Get the front end as high as possible, let the motor run with the radiator cap OFF (important!), and heater on HIGH. Let it idle for as long as it takes to get warm...as this point, check the lower radiator hose...I'll bet it's still cold.

Run the engine UNTIL the temp gauge starts to read H...then turn it off. Have a sandwich and a beer. Come back to the car after ~15 minutes.

By now, some of the heat from the block has soaked into the thermostat housing and the thermostat itself.

Run the motor again, watching the temp gauge. Feel the lower rad hose (BTW, don't get a finger caught in a belt when you do this)...lower hose will still be cool.

When it starts to overheat again, turn it off, let it sit.

Rinse and repeat as necessary.

After a few times, the lower rad hose will be warm/hot to indicate coolant flow, so you'll know the thermostat 'popped' finally.

Drive the car around the block, do a once-over check for tools under the hood, and you're done.
