Yes.
only way to change lower radiator hose is to get underneath the vehicle there is a fawcet on bottom of radiator to dump coolant, then remove hose from underneath vehicle
The only way to drain all the coolant is to unhook the bottom radiator hose. The radiator does NOT have a drain vale.
if there is no drain petcock on lower radiator tank, removing bottom radiator hose at radiator is the only way to drain radiator
There is a small brass valve on the top of the thermostat housing where it attaches to the top radiator hose. Loosen it and then fill the radiator until coolant comes out of the valve and then quickly close it. This is only for an impala with the 3.8 liter engine though I believe there are two valves on the 3.4.
The heater core has no overflow hose. Cooling system is a closed loop system and the only overflow hose is the one going from the radiator cap to the reservoir. A thermostat that is stuck closed will cause the engine to overheat. Drain and flush the radiator, replace the thermostat, install a 50/50 mix of antifreeze and distilled water, bleed air from the system. You may also need to replace the radiator cap. Be sure and replace these parts with OEM parts.The heater core has no overflow hose.

If it is a hose, that runs from a hardline to a caliper or from a hard line to the hardline located on the axle, then you simply remove the old one, using a line wrench, install the new one, and bleed the brakes. To bleed the brakes, you start with the wheel farthest from the master cylinder, but if you only replaced one hose, then only bleed that one. If you must replace a line, then remove that line, either have someone or make up a new line yourself, install the new line, and bleed the brakes.

On a 1999 Lincoln continental the thermostat is located by following the lower radiator hose from the radiator to the engine. It is easily accessible from underneath on the front passenger side. Remove small over flow hose only their is no need to remove lower radiator hose and once you remove the two bolts the housing will come off with the lower radiator hose attached hose still attached.AnswerFollow lower radiator hose from radiator to engine on 1999 Lincoln Continental V8.
there is only one hose on the top of the radiator. the other hose is on the same side of the radiator but on the bottom. the top hose connects to the port on the side of the cylander head closest to the front of the car. the bottom radiator hose connects the the port on the side of the head closest to the fire wall. hope that answered your Q
That engine has to be refilled with coolant in a manner that allows the air to escape. There could be air trapped in the cooling system from not having it filled properly after the radiator was replaced. Here is the way to get air out: It would be good to start with only a partially filled system. Open the drain cock of the radiator and collect coolant fluid. It may not begin to outflow very much until you notice also that the thermostat housing has a bleed valve which if you open it will allow the fluid to drain from the radiator more rapidly. Drain about 3 quarts of coolant in a pan for reuse; then close the radiator drain cock. Put a 4' length of clear plastic hose on the thermostat housing bleed valve nipple and direct the hose over the front of the car to a clean container to catch the coolant as you refill the system (You don't want coolant to get on the drive belts). Then take the cap off the recovery bottle and slowly fill the coolant recovery bottle until fluid starts to flow out of the clear hose. While adding coolant slowly as necessary to keep it running from the 4" hose, gently squeeze on the top radiator hose until all the air is exhausted from the system via the bleed valve hose. The outflow from the hose should have no air showing up. Close the bleed valve and fill the system the rest of the way until it reaches the to the mark on the side of the overflow bottle. Remove the hose from the bleeder valve nipple.
disconnect bottom and top radiator hose then hose from filler tank, plus small overflow hose . unplug electric fans then undo 2 bolts at top holding radiator in then lift out with fans attached. no bolts at bottom only slots
If you follow the bottom hose on your radiator it will lead you to it. You will have to remove 3 bolts on the thermostat housing to get to it but it should only take you about 20 minutes to change it out.
