Re: don't have any heat
Usually at the top of the hose that goes into the throttle body in that main hose is where it should be but do this when the engine has cooled down and then unscrew the clamp and the thermostat should be inside the throttle body and then just pull it out with your fingers. PS you will loose some antifreeze doing this so this is normal. If this solution don't help you then just google what you need to do or look on you tube and there are some repair videos on there as well just type in what you are looking for.

are you installing the correct thermostat the right in the head or block
3 thermostats indicate incorrect fitment method
heater hoses run either way as the water is pushed through the heater core by the pump
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: 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
the rqad hoses are dont from top and botom
you do not need to remove the rad fan to repair the hoses
you need to jack up the car and remove the bely pan if the lower rad hose goes to **** and fix it from under side if top hose goes then it ir replaced from thr top
good luck and arent you glad you bought a beemer
First make sure engine is cool.
-Put drain pan under car, coolant will run out.
-Remove the TOP radiator hose that runs to the metal thermastat housing. Coolant will now be running out, try and direct it to the drain pan below.
-Remove the thermastat housing, BEFORE removing the thermastat make sure you TAKE NOTE at how it is situated in the casting.
- Take the thermastat housing and run a wire brush on the flat spot were the old gasket material is.
-Both mating sides of the thermastat housing MUST BE PERFECTLY CLEAN. There can not be any old gasket material left.
-Insatll new thermastat.
-Put a very light amount of PERMATEX orange high temp. silicone on BOTH sides of the new gasket.
-Put a small amount on bolt threads also.
-Now install thermastat housing, and bolts.
-Tighten bolts down a little at a time, alternating between the two, unitl till they are tight.
-Install the radiator hose, and tighten hose clamp.
-Remove radiator cap, pour in coolant, until it sits just below the radiator cap neck. This may take a little time as the system has some air in it.
-Install the radiator cap. Make sure you radiator overflow tank is filled properly.
-Remove the drain pan, make SURE ALL the tools use used are secure, and out of the engine bay.
-Start engine, and place your heater control to 'HEAT"
-Let engine run until the top radiator hose is hot, which means you thermastat has opened.
-Keep watching the engine temp AT ALL TIMES, we wnat to make sure there is no air in the system.
-Inspect for any leaks. Now when the top radiator hose is hot make sure the hose clamp is tight.
Please let me know how it goes.
Hi to change your thermostat ..disconnect your battery .follow the top rad hose to you motor .where the hose connects to the top of your motor there is a thermostat under neath the thermostat housing remove rad cap ..when cool only ....drain rad ,bottom of your rad there is a bleeder . use a good leak proof container to keep antifreeze from going on the ground ...if you spill any ..make sure you wipe it all up ...it is very poisonous to small animals ect You will have to gain access to your thermostat ,so remove all things that are in the area where the hose goes too ...the motor .First remove the hose connected to the thermostat housing ..remove thermostat housing ...usually a few bolts ....under neath there is a thermostat ....and a gasket ..once you remove the thermostat ....be sure to put the new one back the same way you took the old one out ....plug the hole with a small rag ....any extra rad fluid spilling on the motor ect ...wipe it up it is corrosive ...to wires ect Before changing the new thermostat ...use a scraper to clean the area where the gasket sits ,put a small cloth in the whole before you clean to make sure you don't leave any dirt in the hole ...i usually use a shop vac to clean the area after i finish scraping the area ... buy a good gasket sealant ...new thermostat should come with new gasket ....put new gasket sealant on the gasket so it will not move while trying to install the thermostat housing,be sure to line up the holes in the gasket ...to where the bolts will be installed later . Place new thermostat in then your new gasket ..in the hole .also remember to clean the thermostat housing too ...before reinstalling ....tighten bolts by hand first hand ,use a ratchet....after tightening ....tighten about a half turn ...don't over tighten ,you could break the bolts ,and it's not good to over tighten because of the new gasket also ...put back rad hose to thermostat housing tighten well ,then tighten bleeder on rad ...if you havent changed your antifreexe in some time, buy new antifreeze ..if you are not sure how to mix it ..buy pre mixed antifreeze,fill rad ,connect battery ...start motor ....set heating controls to max ...and blower to the highest setting ,keep filling rad while motor heats up ..it will bubble some ....once you feel the rad is completly filled ...put rad cap on properly ...in your resorvior where you put antifreeze in, fill it to where it should be filled too ..there is usullay a mark to tell how much it can be filled to .check inside your vehicle to see if ther effecient heat comming out your vents .it might take a few days or so for the air to come out of the rad ...ect ....also in a day ..check to see if there are any leaks ...tighten things up more if need be ..... good luck ...let me know how you make out ... Just to let you know ...you can buy an all season thermostat so you will not have to change it every different season from summer to winter ....
A tee is located to the right hand side of the intake manifold, on top you should see the coolant system cap, its silver in color and is about 2-3 inches in diameter. This tee is the thermostat housing, it goes to your radiator and engine block, remove it from the block and you should see the thermostat. Remember when replacing the thermostat, the spring side goes into the block!
2.0L and 2.4L it is under where the upper rad hose hooks to the engine. 2.5L it is under where the lower rad hose hooks to the engine.
