Re: leaking from conection at gasket and thermastat
The gasket may have slipped out of place while placing the bolts in the holes. Remove it again. Make sure the thermostat is orientated correctly. Apply a gasket tack onto the housing apply the gasket and let dry until it will stay in place. Carefully place the housing in place. Start all three bolts before tightening them. Also just in case, check the thermostat housing for cracks, and make sure the hose end is not damaged from the hose clamp, or when you removed the hose. Sometimes people try to pry the hose loose with a flat tip screwdriver and unknowingly damage the hose. If you follow the steps above you should correct the problem. Good luck.

Remove the radiator hose from
the thermostat housing cover by removing the band clamp that holds the
hose to the cover. This is done with a Phillips screwdriver. Slide the
band clamp back away from the housing and pull the hose off.
2 Remove the two bolts that hold
the thermostat housing cover to the top of the Elantra intake manifold
with an adjustable wrench. The bolts will be reused. They should not be
3 Remove the old gasket that was
pressed between the intake manifold and the thermostat housing cover.
It's a paper gasket and should pull off of the intake in one piece.
Remove the thermostat from inside of the intake manifold by pulling up
on it. The gasket and thermostat can be discarded.
4 Place the new thermostat into
the intake manifold of the Hyundai Elantra. The thermostat must be
placed with the top sticking out of the intake manifold for it to work
properly. Use the old thermostat to orientate the new one.
5 Place a small amount of PVC
gasket sealer around the thermostat on the base of the intake manifold.
Allow the PVC to dry for ten minutes and then place the thermostat
gasket on top of the gasket sealer. Place a small amount of PVC gasket
sealer on top of the paper gasket and allow to dry for ten minutes.
6 Place the thermostat housing
cover onto the gasket and bolt it into place with the original bolts.
You should see a small amount of PVC gasket sealer squeeze out between
the housing and the intake. This is normal and it should be left in
place. Once it dries, it will add additional seal protection and prevent
7 Place the radiator hose back on
to the thermostat housing cover and fix it into place by tightening the
band clamp with a screw driver. Your Hyundai Elantra is now ready to

ok. It's fairly straight forward -- Make sure engine is cool, locate the hose leading from radiator to the top of the engine, you should find a housing with two bolts one on each side. remove the hose, bolts and housing, clean all smooth surfaces with scraper then sand paper to remove all old gasket material, replace thermostat, seal with gasket sealer and torque bolts back on to specification (typically a good solid snug would do) Best regards Ck
YES! DRAIN THE RADIATOR! THE THERMASTAT IS AT THE ENGINE SIDE OF THE TOP RADIATOR HOSE! REMOVE THE HOSE! AND THE THERMASTAT HOUSING HAS TWO BOLTS HOLDING IT ON! REMOVE THE TWO BOLTS, AND THE HOUSING! CLEAN THE AREA AROUND THE BASE OF THE HOUSING! SCRAP OFF THE OLD GASKET FROM THE HOUSING, AND ON THE ENGINE! REPLACE THE GASKET WITH A NEW ONE! PLACE THE NEW THERMASTAT IN THE SAME DIRECTION AS THE OLD ONE COMES OUT! REPLACE THE HOUSING, TIGHTEN THE BOLTS, AND PUT THE RADIATOR HOSE BACK ON, RETIGHTEN IT, AND FILL WITH ANTIFREEZE, AND CHECK FOR LEAKS!
Follow the upper radiator hose back to where is clamped to the engine. The part that the hose clamps to is called the goose neck the t.stat is under this part. You will need to drain some coolant from the radiator not all about a QT. or so remove the upper hose clamp twist the hose to brake the seal remove the hose move to one side. Remove the two bolts that hold the goose neck down remove goose neck remove T.stat it will lift out. Clean all of the old gasket off bolth surfaces THIS IMPORTANT THE SURFACES NEED TO BE CLEAN OR YOU CAN CRACK THE NECK OR HAVE LEAKING AFTER INSTALLITION. Put the new T. stat in place put the new gasket in place you may want to use a gasket sealer it will hold the gasket in place. Put the two bolts in tighten then evenly go back and forth between them so to tighten them in stages they olny 18 ft lbs of torque DON,T TRY TO OVER TIGHTEN that is what the gasket is for reconnect your radiator hose tighten the clamp put your antifreeze back in start and check for any leaks sometimes you have to repisition the hose slightly and your done

LOOSEN HOSE CLAMP REMOVE RADIATOR HOSE FROM THERMOSTAT HOUSING.THEN LOOSEN HOUSING BOLTS.REMOVE THERMOSTAT HOUSING AND THERMOSTAT.CLEAN BOTH THE THERMOSTAT HOUSING SURFACE AND INTAKE SURFACE YOU CAN USE ACETATE OR BRAKE CLEANER AND SCOTCH BRITES ROLL OF CLEAN PAPER TOWEL. AFTER CLEANING HOUSING AND INTAKE SURFACE MAKE SURFACE CLEAN SMOOTH FROM THE DEBRIS WHEN DONE. TAKE THERMOSTAT PUT GASKET SEALER ON BOTH SIDES OF GASKET PUT GASKET TO THERMOSTAT HOUSING MAKE SURE GASKET AND THERMOSTAT HOUSING HOLES ALIGN CORRECTLY.NOW PLACE NEW THERMOSTAT IN PLACE IN THE INTAKE.MAKE SURE THERMOSTAT SPRING END GOES TOWARD ENGINE FACING DOWN.THEN INSTALL THERMOSTAT HOUSING WITH GASKET TO THE INTAKE.TORQUE THERMOSTAT HOUSING BOLTS TO 20 FT LBS.WAIT 1 HOUR BEFORE POURING ANTIFREEZE BACK IN THE COOLANT SYSTEM GIVE THERMOSTAT GASKET SEALER LITTLE TIME TO CURE.SO YOU WONT HAVE COOLANT LEAKS.NOW IF THERMOSTAT HAS THE LARGE O- RING ON IT YOU DONT HAVE A THERMOSTAT HOUSING GASKET THE THERMOSTAT O- RING IS THE SEAL THAT HOLDS COOLANT INSTEAD OF GASKET.WHEN THERMOSTAT AND HOUSING IN PLACE.INSTALL RADIATOR HOSE TO THERMOSTAT HOUSING TIGHTEN HOSE CLAMP.THEN FILL RADIATOR BACK UP WITH THE COOLANT YOU DRAIN OUT.START VECHICLE UP. THEN CHECK FOR LEAKS.
Your Thermastat is located in a Dome Shaped Housing,just take your hand put it on upper radiator hose and follow it to the engine ,you'll run into a hose clamp around the hose thats holding it on the Thermastat Housing.
Make sure your car is cold, then put a pan underneath vehicle below the thermastat housing,You'll loose a Little Coolant ,So this Way you can catch it.
Just Loosen the Rad. Hose Clamp and Pull off the Hose from the Thermastat Housing.Then you'll have a couple bolts holding on the Housing,Remove the Bolts and The Housing should be FREE to come off.If its a Little Stubborn ,Lightly Tap on It with a Plastic or Rubber Hammer a nd it will come off.Your Thermastat is under the Housing.
After off Clean Both Surfaces on the Housing remove All the Old Gasket material and Gasket Sealer .Then just put your new thermastat housing in with the Spring part facing Up.
Put Gasket Sealer on The Thermastat Housing and Put new Gasket on and Line up your Bolts Holes.
And Also piut a Small bead og Gasket Sealer on The Engines Surface. Tighten Down Good and Snug ,But Don't Over Tighten.
Put the Hose back on Tighten Clamp and Fill Radiator Back up to Top.

Hi This is d_hubbs: Removal and replacement of your water pump.I'm assuming you have a 2.5 Engine.You did'nt give your engine Information but about 75% of your Year and Model had the 2.5 in them.
1st start by disconnecting your negative cable on your Battery. Then Drain your Coolant into a Container: then remove your drive belts remove your fan from the water pump: You probally should also remove your alternator and A/C Compressor to make it easier to get to your water pump, now remove your lower Radiator Hose, then remove your water pump mounting bolts, now remove the water pump: Now Clean the water pump surface on your engine where your gasket will be. Besure its Clean Good : NOTE: Sometimes if you purchase a New water pump it will not have the drive belt pulley on it. if this is the case Remove your Pulley from your old Pump and install it on your New pump : now Run some gasket sealer on your new water pump where the gasket will go.put gasket on the new pump lining up your mounting bolt holes.also put a small bead of sealer on the engine where your water pump will mount: now Mount your New water pump to the engine with the Mounting Bolts.Torque the Mounting bolts at 25-30 Foot Lbs.
Inspect your Drive belts and Hoses its a good time to put new ones on if needed.Now put your lower Hose back on-re-install your A/C compressor and Alternator-Put your fan back on-now put All your Drive belts back on be sure to Adjust the Belt Tension and Lock down the Bolts.-Fill your Radiator back up with coolant,If the Fluid you took out is still fairly new ,you can use it. If its Aged best off putting new Coolant. Replace the Battey Cable Start your Car and Check for any Leaks , After your Thermastat opens you'll need to recheck your Coolant Level. if no Leaks and Cooling System is Full you Are Done. Please let me know how my advice and Solutions have Helped you. Thanks for Using FIXYA From d_hubbs
Hi: You'll first want to Drain your Radiator take your radiator cap off so when drain it the coolant will drain freely.Then Drain your raditor you'll find a Drain Tee outlet on the inside bottom of your radiator. And catch the Coolant in a Drain Pan. Standing in Front of your Vehicle you'll see a Hose connected to your Radiator(UPPER RADIATOR HOSE) take your Hand and follow it down to your Engine until you locat a Hose Clamp Remove the hose clamp and work off the top Radiator Hose.Where you removed the hose theres a Dome Shaped Metal Housing,with 2 bolts in it. Take those 2-Bolts out and Remove the Dome Thermastat Housing,Under it You'll Find your Thermostat it shuold come out with a little Resistance. Once its out, Clean Up The Thermastat Dome of any Gasket still left on it, and clean where you remove the Thermastat Surface.To put back just Reverse the Removal Be-sure your Thermastat is put in right and not up side down.Then get some Gasket Sealer Put a Little on the Thermastat Housing where gasket goes and some on the Enging surface and Install your New Thermastat,Be careful when Tightening the 2-Bolts on The Housing. not to Over tighten them.The torque Specs on the 2 bolts range between 10- 15 Foot pounds.You don't want to Strip,
After you get your New Thermastat in and your Radiator Hose on and Clamped.Make Sure you have closed the Drain outlet. then fill with coolant,if your coolant is old i recommend putting new coolant in. I hope this helps You.I;m Sure it Will, But please let me Know through FIXYA by Voting and a Testamony.This way I'll know that my solution was Helpful. Thanks From d_hubbs
