Lower radiator hose - 2002 Mercury Sable

If there is not a pit **** on the bottom or side of the radiator by the lower hose you will need to loosen the lower radiator hose and gently work the lower radiator hose off at the radiator and drain it into a drain pan. If not at the lower radiator and if the water pump connection for the hose is easier to work on you can loosen the clamp on the hose there and pull the radiator hose back and drain it from there. Once it is drained push the hose back in place and tighten the hose clamp. Refill the radiator slowly as not to get an air lock in the radiator, also once you think it is filled start the truck and leave the radiator cap off until the thermostat opens and add more antifreeze to top it off. Hope this helps.

Re: Where is the lower radiator hose?(99)

Stand in front of the car, open the hood, and face the engine.

On the left hand side of the radiator, at the top, is the upper radiator hose; which goes to the upper water pump connection.

On the right hand side of the radiator, from the bottom, is the lower radiator hose; which goes to the lower water pump connection.

Where is the lower radiator hose 99
It is a forum and goes on about draining the radiator.

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

Suzuki factory manual

remove as followed :
1- upper trans cooler line.
2-upper radiator hose.
3-lower trans cooler line.
4-cooling fan electrical connection and retaining bolts .
5-coolig fan.
6-splash guard below lower radiator hose .
7-lower radiator hose from radiator.
8-condenser line retaining clip.
9- condenser to radiator bolts .
10-coolant tank small hose from the radiator .
11-radiator retaining bolts.
12-radiator ....
That's it. feel free to contact me I did this removal more than five times to your grand am type specifically .

REMOVAL

Section 303-03: Cooling, Engine 1997 Explorer, Mountaineer Workshop Manual REMOVAL AND INSTALLATION Radiator - 4.0L Removal

1. NOTE: Refer to following illustrations.
   Drain the cooling system by removing the radiator cap (8100) and attaching a 9.5 mm (3/8 inch) inside diameter hose to the draincock nipple, located at the lower rear corner of the radiator tank. Then, open the radiator draincock (8115) and allow the coolant to flow through the hose into a suitable container.

1. Loosen hose clamps at throttle body and engine air cleaner assembly. Remove air cleaner outlet tube and position aside.

1. Remove radiator overflow hose from the radiator, disconnect two hose locators at top of radiator and position hose aside.

1. Remove two fans shroud bolts. Lift the fan shroud out of the lower retaining clips and position it on the fan blade.

1. Position upper and lower radiator hose clamps, remove hose from radiator and position it on the fan blade.

1. Disconnect the two transmission cooling lines from the oil cooler fittings on the radiator, install protective caps over lines and position aside.

1. Remove two upper radiator bolts.

1. Tilt the radiator back (rearward) approximately 25 mm (one inch) and lift directly upward, clear of the radiator support bracket and the fan blade.

Installation

1. Position the radiator into engine compartments, make sure that mountings on both tanks are inserted into radiator support brackets. Install radiator retaining bolts. Tighten to 6-8 - (54-70 lb-in).

1. Install upper radiator hose and position hose clamp. Tighten to 3 - (26 lb-in).

1. Install lower radiator hose and position hose clamp. Tighten to 3 - (26 lb-in).

1. Position fan shroud in lower retaining clips and install upper bolts. Torque to 6-8 - (54-70 lb-in).

1. Position radiator overflow hose, connect to radiator and locators.

1. Position air cleaner outlet tube to throttle body and air cleaner assembly. Tighten to 2-3 - (18-27 lb-in).

1. Fill the cooling system; refer to Cooling System Draining, Filling and Bleeding in this section.

Disconnect battery ground cable. Remove battery. Remove battery tray. Remove clip retaining contant control relay module and position module aside. Remove radiator cap. Raise vehicle front end as high as possible. Remove radiator splash shield. Drain radiator. Remove the radiator mounting bracket assembly. Remove lower radiator hose. Partially lower vehicle.

Position transmission oil cooler tube and install transmission oil cooler tube bracket. Install lower transmission oil cooler tube. Install lower transmission oil cooler tube clips. Install lower radiator hose. Install radiator mounting bracket assembly. Tighten bolts. Install radiator splash shield. Lower vehicle. Install upper tranmission oil cooler tube. Install upper transmission oil cooler tube clips. Install upper A/C condenser core retaining bolts. Tighten bolts. Install radiator overflow hose and tighten clamps securely. Install upper radiator hose. Position constant control relay module and clip securely. Install battery tray. Install battery. Connect battery ground cable. Fill and bleed cooling system. Start engine and inspect for leaks.

depending on how many miles you have on the car i would look at the lower hose first; the other common problem on a 93 cav would be the lower radiator neck or radiator leak; the lower hose has less pressure on it than the upper so sometimes finding the leak can be tricky. with the engine off and cold squeeze the lower hose by the radiator to see if any fluid comes out. otherwise you would have to pressurize the system to find the leak
