2001 LS. Where is the fuse for the radiator fan?

The temperature switch on the side of the upper radiator hose is not working. That is, if the engine is hot. Boiling over - need to check thermostat. Grab on to upper hose (should be hot) than with engine off, grab bottom radiator hose. It also should be same temperature as top. If so, thermostat ok. Electric radiator fan - turn Ac on. Fans should run. No, check fuses & relay. Mechanical fan - with engine off, the blade should be stiff to turn. Easy, replace fan clutch. Usually, low level of water is most common. Wish you well.

If you are referring to the cooling fan in the front of the radiator, it is a hydraulic system, not electric in the LS from 2000-2002 and thus has no fuse. If you are referring to the blower motor, I can give you that fuse location.

check the radiator cap and the fan clutch

do u hav the rite thermostat or is it in correct--shud be closed at startup-if not takes long time to get at operating temp and bad gas milage too

Physically look in the radiator under the cap(if one exsist's) when cool, for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.

If radiator is low on coolant fill it to overflowing, replace cap, and check that coolant overflow is filled to the COLD line or mark. The overflow is normally where you would add coolant. (never overfill the overflow)After refilling as outlined above, check the level every morning for 2 or 3 days until coolant level stops dropping below the cold mark and add coolant to the overflow ONLY. Do not open the radiator cap. Also, if you have even a tiny coolant leak anywhere in the system, air will get drawn in, instead of coolant from the overflow.

For more OVERHEATING PROBLEMS try these...
Radiator fins dirty, clean with a strong stream of water, not high pressure water.
Radiator clogged, try backflushing it, or replace.
Thermostat stuck open or shut, replace it.
Water pump worn out, can no longer move enough coolant, replace it.
Fan shroud broken or missing....
Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.
Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.
Air dam under front bumper is gone, loose, or broken. It actually has a purpose other than scraping on the driveway or curbs. It forces air up into and thru the condenser and radiator. If it's loose, airflow can actually push it out of place making it useless or blocking the airflow. Along with that, there may also be a plastic piece attached to the bottom of, and wraps up behind the bumper. If it

First when car is running hot stop and pop the hood check and see if the electric cooling fans are running. Second have your radiator cap checked, replace if bad. If neither or these are the issue, with the engine cold start it up and remove the radiator cap. It will take a couple minutes for the engine to warm up enough to open the thermostat. After it gets warm enough that your thermostat opens, (5 to 10 minutes) you should see the fluid in the radiator start to circulate. If this doesn't happen your water pump is out and needs to be replaced. Back to the first thing if your fans aren't kicking on check all your fuses in your engine compartment first. If you narrow down the problem to one of these and need more assistance, just reply to this comment and I will help you further.

Radiator cooling fan is not electric, it is driven by a silly hydraulic pump which is located low on the passenger side of the engine above the alternator. All 2000-2002 LS's have this system. Most likely either the motor or pump has failed.

Well....deep breath.......it's not bad.

1. Check your radiator coolant level

2. Check/Test radiator fan

3. Test/Replace radiator cooling fan relay

4. Replace the thermostat

5. Check/Replace the coolant temp sensor

6. Replace the water pump.

Radiator fan fuse is fuse # 5 (40 amp/Green) located behind the interior fuse access panel on the left side of the instrument panel next to the steering column. Also, in the underhood Power distribution center, next to the air cleaner filter are two black fan relays: high speed (F) at the far left, second row down and a low speed, 1st one to the right on the bottom row.
