Where is the waterpump to add coolant and water in santafe 2005?


The water pump is enclosed on the front of the engine. The bottom radiator hose connects to the water pump inlet.
You do not add coolant to the water pump. You add a 50-50 mix of antifreeze and water into the radiator cap opening. Or you can buy the coolant already mixed with water and just pour it into the radiator.

The coolant system uses the water pump to circulate the coolant through the engine and then into the radiator via the upper radiator hose for cooling it off, and it then goes back into the engine through the bottom radiator hose. When the engine is warmed up, the coolant constantly circulates through the engine to radiator and back into the engine.

I have a Eurovan and it doesn't hold water. It goes right to the ground. Is that a cracked head?


It could be a cracked head, a cracked engine block, a torn hose, a really bad water pump, a bad radiator...Pretty much anything. You have to look to see exactly where it is coming from when you pour the water in.

When the engine has cooled down check the coolant level and make sure it is full. If the coolant is in the operating range, I would suspect one of two problems, water pump or thermostat. With the engine on check to make sure the serpentine belt (should be only one belt for your engine) is turning the pulley for your water pump is rotating without restriction.
The thermostat will allow coolant flow when it reaches operating temperate. You may be able to squeeze the hose and feel the pressure of the water flow when the engine is heating up. Be careful of loose fitting clothes and your body stays away from moving parts of the engine. If you have no flow check the thermostat first and if the flow of coolant is not circulating when the engine warms up you will have to drain the coolant to remove the pump to check the operation and replace if necessary.
The thermostat is inexpensive but you may have to drain and refill the radiator. If the water will not flow though the radiator it will not cool the engine. Follow the large radiator hose to the engine block. The hose connects to a cast iron elbow with two bolts holding it to the block. Drain the radiator fluid, unbolt the two bolts and you should see the thermostat. Clean off the old gasket off the block and elbow then bolt the elbow and new thermostat with gasket to the block to the manufactures torque specs. I would buy some radiator flush if it has not been flushes for several years. Fill the radiator with the correct ratio of coolant and water replace the cap then run the engine for 15 minutes and look for leaks or listen for hissing from the leaks.

The small elbow shaped hose coming out of the manifold and into the belt tensioner is leaking coolant. What is this part and how easy to replace?


This is a 3100, or a 3400 V6 engine? It should be one of the water hoses that connects the tube on the front to the water pump, it is a preformed hose availiable from many parts stores and is not difficult to replace, if you drain a little coolant out before you take it off you will lose less coolant in replacement, be sure to refill coolant after your done. Hope this helps, let me know

Over heating


The thermostat will be under an elbow shaped (90 degree) short metal fixing connected to the engine block. The other end will have a rubber hose connected to it. the metel fixing should have 2 or 3 bolts holding it to the block. Undo these and the thermostat is underneath. Lift it out and put it in a container. Pour boiling water on it and see if it makes a loud 'Pop' if it doesn't then you will need a new one.

This is no joke, I can,t fine where my thermostat is in my 1997 merc sable, ,i even followed the top hose back to the engine block


if you follow the "upper" radiator hose from the radiator to the engine it should have a metal piece that bolts to the car ( usually with only 2 bolts) and also the hose is clamped to it. it most likely has a domed shape to an elbow looking piece. take the "upper " radiator hose from where it connects to the engine. remove the bolts that hold this metal piece to the engine that you just took the hose off of. the thermostat "should" be located under this piece. you must take that metal elbow thing off from car to access the thermostat. where it bolts to the engine it most likely will have only 2 bolts and where that connects to the engine will be a gasket and it will be kinda football shaped. a lot of cars will also have a brass flat screw on top of this domed shaped elbow. that will be the give away to that that is where it is. what you do is when the car is running and the coolant starts to get warm, you back out the brass screw a little. this will let the air escape thats trapped and when coolant starts to escape tighten the screw back down. now you have the air out of the system after youve replaced the thermostat. I hope this helps....

Leaking coolant


These plastic elbows (3.8L Engine) do fail. To the best of my knowledge this is a dealer only item, which is not a big deal as the cost is low (in terms of car repair). Remove the alternator to gain access to the elbow. Monitor the coolant level following repair.

As you probably know, don't let the engine run low on coolant as engine damage will follow.
