Needing Thermostat housing

are you getting sufficient flow through the cooling system,i.e. clogged radiator,bad water pump,stuck thermostat. also when the head was repaired , was it pressure test for cracks? valves out of adjustment will cause the engine to run poorly but not overheat.

Locate upper radiator hose.

It will attach to the top or front of your engine block via thermostat housing.

Remove hose from thermostat housing,catch coolent accordingly. Then remove thermostat housing, usually two or three bolts. If housing does not come off easy you may try an jiggle it loose, if no luck get a flathead and pry it off, there may be a thermostat housing gasket, or possibly simple RTV silicone gasket maker. Once housing is off pull thermostat out. Noting it's position, mostthermostats have a small dimple of hole indicating upwards position.

Once removed use razor blade to remove old gasket and or RTV.

If it's a paper gasket, buy a new gasket with your new thermostat. (some thermostats come with gaskets, others dont). Also while at the parts store pick up a tube of silicone RTV black gasket maker.

Now! Once everything is cleaned, mock up the gasket with the housing so you know proper placement. open gasket maker, lay a 2mm bead (read packaging to confirm bead) along the gasket on bock sides leaving no open parts, leave the bead, don't spread it around with your finger.

Ok now put thermostat in block, then gasket and housing. Try and install it one swift motion without making a mess. You do not want that RTV to leak out the sides and be all messy!

Torque both housing bolts to factory spec. I you don't know spec call autozone, or just tighten them to your liking. Not to tight.

Crack open a miller light and wait for RTV to set up. When set up( again read packaging) then install radiator hose. And clamp it down, not to tight, the clamp may puncture the hose if swollen or old.

Now, tour good to go, but you may need to bleed air out the system, I suggest taking it to a jiffy lube or shop n asking them to do it real quick, or just ask another question on here and I'll explain!

Good luck.

YEP YOU HAVE LEAK AT THERMOSTAT HOUSING.YOU NEED REMOVE THERMOSTAT HOUSING OUTLET AND CLEAN THE MATING SURFACE THOROUGHLYTHEN APPLY RTV SEALANT IN THE GROOVE OF THE WATER OUT LET HOUSING.INSTALL THERMOSTAT WITH SPRING TOWARD THE ENGINE TORQUE THERMOSTAT OUTLET HOUSING BOLTS 89 INCH LBS.IF STILL LEAKS OUTLET HOUSING COULD HAVE CRACK IN IT CAUSING LEAKING.

Have you checked inside vehicle to ensure there is no heater core leak? If not leak found there and leak at thermostat housing is not severe once at normal operating temp, issue could be with a cylinder head crack to an exhaust valve which generally vents coolant to exhaust with very little or none showing in oil.

thermostat housing is on engine block, left side as you look at engine. Thick black rubber hose leads from radiator to the thermostat. Two bolts to remove, be sure to clean all stuck- on sealant so you get a smooth, flat surface when reinstalling thermostat housing.

You have clean the surface all parts and replace the seals so is the one way that not leaking, If you thermostat housing has two parts ot metal, if not, you have to buy another one with the housing more.

Thermostat housing it sounds like.The Daewoo Laganza use GM Parts so you can get one from your local dealers.If this engine is the ECOTECH.Good luck

in the fron of the cylinder head ,you will need to remove the timing belt to get at it

thermostat in a 99 maxima is right above the alternator. just look down and you will see a hose clamp and a hose. that's the thermostat housing. you will remove the whole housing (3 bolts),because that's the whole thermostat.

well The same thing happened to me and I have a Answer!
