Call a mobile car repair service to advise you on emptying car as it can be an ******* to drain the fuel out as where do you get rid of the fuel

Made a video showing how I replaced the radiator on my 2005 Hyundai Santa Fe and in the process show how to find the drain plug.

I took off the lower radiator hose in my shop

it aint got one,you undo the radiator bottom hose to drain the engine......

REMOVAL & INSTALLATION (4 Cyl. eng.) CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

1. Position a suitable drain pan under the radiator drain **** and drain the cooling system.
2. On the 1MZ-FE engine, remove the air cleaner cap assembly. Be sure to label all wiring disconnected.
3. Disconnect the water temperature switch harness from the water inlet housing (except 5S-FE engines).
4. Remove the oil filter on 5S-FE engines. On the 1MZ-FE engines, remove the heater hose covering the housing.
5. Loosen the hose clamp and disconnect the lower radiator hose from the water inlet housing.
6. Remove the two nuts from the water inlet housing and remove the housing from the water pump studs.
7. Remove the thermostat and rubber O-ring gasket from the water inlet housing. To install:
   
8. Make sure all the gasket surfaces are clean. Clean the inside of the inlet housing and the radiator hose connection with a rag.
9. Install the new rubber O-ring gasket onto the thermostat. On 2SE and 3S-FE engines, align the jiggle valve of the thermostat with the protrusion on the water inlet housing. On 5S-FE engines, align the jiggle valve with the upper side of the stud bolt. On 2VZ-FE and 3VZ-FE engines, align the jiggle valve with the stud bolt. Insert the thermostat into the housing. Fig. 1: Remove the thermostat housing from the engine with the coolant temperature sensor - 1MZ-FE engine
   Fig. 2: Removing the thermostat from the engine - 1MZ-FE engine
   Fig. 3: Always discard the old O-ring from the thermostat, if reusing the old component
   Fig. 4: Always replace the thermostat with the correct temperature specifications
   Fig. 5: Line-up the jiggle valve with the protrusion on the housing - 5S-FE engine
   
   
10. Position the water inlet housing with the thermostat over the studs on the water pump and install the two nuts. Tighten the two nuts to 78 inch lbs. (9 Nm) on 4 cyl. engines, 2VZ-FE and 3VZ-FE; 14 ft. lbs. (20 Nm) and 69 inch lbs. (8 Nm) on 1MZ-FE engines. Fig. 6: Thermostat installation - 2VZ-FE and 3VZ-FE engines
    NOTE: Don't forget to install a new O-ring onto the water inlet pipe. Apply soapy water to the O-ring prior to installation.
    
11. Connect the lower radiator hose to the inlet housing and install the hose clamp. On the 3VZ-FE, tighten the bolt holding the water inlet hose to the alternator belt adjusting bar to 14 ft. lbs. (20 Nm). On the 1MZ-FE engine, tighten the bolt retaining the water inlet pipe to the cylinder head to 14 ft. lbs. (20 Nm).
12. Attach the water temperature switch connector.
13. On the 1MZ-FE engines, install the heater hose removed.
14. Install the oil filter and check the oil level if removed. Install the air cleaner cap assembly on the 1MZ-FE engines.
15. Fill the cooling system with a good brand of ethylene glycol based coolant.
16. Start the engine and inspect for leaks.

Is what the liquid plain water or coolant (water mixed with antifreeze). touch and smell the liquid, no smell = water, antifreeze smell and oily feel = coolant.
If plain water, could be Air Condition condensation dripping from condensation drain which is normal. (this drain is usually located near the center of the vehicle).
If coolant, could be leak(s) from: radiator, radiator hose, heater hose, water pump, engine freeze plug. A coolant system pressure test should show what is leaking.

There is a metal coolant crossover tube with 5 gaskets 2 hoses and a thermostat above the transaxle anyone or all of these could be leaking

Below are instructions and a diagram for removing the radiator from your Santa Fe. There's nothing involving the motor mounts. Best of luck and please post back with any questions or just to rate the solution. Greg

1. Drain the cooling system. Remove the radiator cap to speed draining.
2. Remove the inlet hose from the radiator.
3. Remove the transmission oil cooler lines from the retainer clip at the bottom of the cooling fan shroud.
4. Remove the fan shroud clip from the condenser tubes.
5. Remove the bolt that connects the fan shroud to the condenser hold down bracket.
6. Remove the air deflectors from the top of the radiator.
7. Remove the cooling fan shroud bolts.
8. Remove the coolant reservoir hose from the radiator overflow neck.
9. Remove the radiator upper support brackets and bolts that connect to the fan shroud.
10. Disconnect the engine cooling fan motors electrical connectors.
11. Remove the cooling fan motors electrical harness from the fan shroud clips.
12. Remove the cooling fan shroud.
13. Remove the outlet hose from the radiator.
14. Disconnect the transaxle oil cooler pipes from the radiator.
15. Tilt the top of the radiator rearward.
16. Remove the condenser hold down bracket from the radiator.
17. Lift the condenser from the mounting tabs on the radiator and position the condenser aside.
18. Remove the radiator.

on one side of the radiator near the bottom is a petcock. open the petcock to drain. Take the radiator cap off to do this to allow it to vent so it will drain out.
If you cant find it, remove the bottom hose off the radiator. This is messy but effective.
