Disconnect your lower radiator hose...or open the petcock located on the lower corner of your radiator. Be sure to have your cap off.

No pressure in radiator 454runs at 150 deg

Probably a bad radiator cap. If that doesn't work then a radiator flush might be required.

HEAT NOT WORKIN IN 1989 CADILLAC?

either the blower motor is bad or you need to flush out the heater core.due to the age of the vehicle its probably clogged up with deposits and needs to be flushed out with air pressure or you can try hooking up your garden hose to it and flushi9ng it out that way

How do I drain the radiator on a 1995 cadillac deville

its on the side of the radiator ,down towards the bottom of it,,on the drivers side,be care full because this stuff will gush out of it if you remove the drain plug all the way,and you need a good sized pan for it because it holds a lot of coolant,good luck,i hope this helps

Flush radiator and cooling system on 1997 Calillac DeVille Concou

your radiator has a pecock on the bottom of it screw it out then you can run water through a hose behind it once it stops draining to get any residue out as far as the engine youll never truly get all of the old coolant out without tearing it down and putting it back together so flushing the radiator is just fine.

Car cuts off when hot

pull bottom rad hose it will drain. You might need to replace your thermostat there might be a vapour lock also you should have a screw in your cooling system somewhere for bleeding it(letting the air out)
