Purchasing 1996 grand marquis with 120k miles, should I replace intake manifold before it fails?

Intake manifolds are metal and don't usually fail. The gaskets that seal it to the engine may leak with time. If it isn't broke, don't fix it. Your major concern should be the condition of all rubber hoses including the flexible brake line hoses on the front wheels. There are metal springs inside the radiator hoses that help prevent the hoses from collapsing. Squeeze the hoses at the radiator connections (cold engine) to see if they feel gummy , have cracks, and still have the springs inside.

Where is the freeze plug located at on a 1989 cressida

The freezer plug is located on the left side of the motor under the exhaust manifold towards the back.I think its visible if you take off the metal heat shield that's on the manifold or maybe from the bottom if you lift the car.If its not leaking from there than it could be coming from the back of the motor. There are hoses, a EGR cooling plate and metal water lines on the motor.

Heater doesnt work but ac does

Assuming the fan blows OK but you have no heat. Go to the firewall and notice where the heater hoses enter and exit the cabin. You'll notice a metal manifold and also a rubber bypass hose that connects the two. This bypass hose is a design problem and causes the coolant to bypass the heater core which is located inside the cabin under the dash. Over time, the heater core gets blocked by gunk and you'll get no heat. All the coolant flows through the bypass hose when this happens. The fix is to flush the heater core itself. It's difficult to access at the firewall, so I disconnect the two hoses at the engine itself and attach a garden hose to flush it. Before doing this you must clamp (vice grips) the bypass hose so that all of the water goes through the heater core.

, apower brakes have no pressure when pedal pushed, no brake line leaks, pushes hard when engine turned off acts like power assist is leaking thru

I would check the medium sized rubber hose that goes to the brake booster from the inlet manifold as it can swell internally and prevent vacuum getting to the power booster. Replace if necessary. I would also check all those pesky little rubber vacuum hoses that are used for pollution control. They tend to go hard and split where they connect to the metal piping if they are over 10 years old, allowing air / vacuum leaks into the inlet manifold. It could also mean that the rubber diaphragm inside the brake booster has developed a leak and causing loss of power assistance.

Tube disconnected fron antifreeze holding tank to wherever it is supposed to go keeps losing antifreeze

there is two small hose come out from reservoir. on of them(rear one) goes to coolant bypass line it is a small metal pipe goes all the way to thermostat housing other hose(front) connected to radiator.
if you lose coolant from the bottom breathing hose on reservoir you may have air in coolant system you should bleed the system.

2003 chevy tahoe no rear heat

I know the earlier tahoe's have two heater lines running from the engine compartment to the rear under the vechile. Those lines could be clogged or pinched shut. What you do is get two hose locking pliers. Go under your truck, they are two metal lines that turn into rubber and back into metal again farther down the line. First, checked for pinched lines. If none, find where the rubber hoses are, clamp them off, remove from metal lines and drain. Use garden hose to flush fresh water through. When water comes through at high pressure and pretty clear, it should be done. Reconnect hoses, top off radiator fluid and it should be fine.
