Thanks alot u guys it's a little project I'm doing to stay busy and doing a little exercise too helps me through out my day.
Not necessary to take the radiator off. The fan nut uses a 32mm wrench and with the tap of a hammer comes lose.
thank you! I wanted to ask that question!

no problem. I have replaced the thermostat and water pump many times and didn't need to remove the radiator.
Turn your fan blade clockwise to undo
Mitch Lock which hoses can you buy because the standard horse don’t match the thermostat housing
I think he said it wasn't necessary but your detail helps.
Thanks for the 22Nm and 10Nm (13mm and 10mm bolts) torque specs. Very helpful
Many thanks, it was helpful video, I'm just changing my e39 528i.. And followed the instructions.
Thanx for the helpful video in how to removed and replace the thermostat 👌
Ive watched so many of your videos, subscribed! :) awesome quality, explanation, video length, and show hows. Im in the market for a 98 328i. When i get it, i will refresh the cooling system, replace alot of sensors, suspension, bushings etc. cuz your help, im gonna do most myself :D! Bye bye lancer es :P
Did you ever buy it ?
Any pointers for removing a stuck thermostat? Mine is stuck...and you just skipped over removing it :(
Hi, thanks for your video it's very interesting, but as said El Salvador, it is not necessary to disassemble the radiator, it must just remove the fan
Wow great video...question on a 03 bmw x5 if my front differential took a crap on me. Now the suv won't move. Can I cut the driveshaft out. So I can drive the car into my garage
hello the arrow on the kept silent calorstat put her ( it ) well has 12 hours ?
Ho makes you when the calorstat lacks it of indication ?
Created a UA-cam just to comment, but keep these video's up man.. I will be buying a E36 Real soon!!
Thanks! I'm looking forward to hearing more from you!
Just bought a "98 328i e36, and I need to know if after fixing this, the car was worth the buy.
HELP
Need help on how to change a thermostat in a 2007 bmw 550i, which also has the same motor as a 650, and the 750 bmw.
Do you have to drain the coolant from the radiator ? Or can you just remove the thermostat and go on with the job ?
Fan clutch is super easy to remove. Just put your wrench on the nut, smack it clockwise with a hammer or sledge (have something soft to stop the wrench like a roll of paper towels) and unwind it clockwise.
Great video, I've watched a lot of yours. I've had one of each s6 e36, with a '97 328i as my current (throwing code P0125). Your vids have helped me with everything that I've needed to repair. Cheers and keep up the awesome work.
have the same thermostat , doesn't come with sensor what did you do ?
Do you need a gasket sealent for the housing or it won't leak
Great video THANKS A MIL!!
My car is saying "check coolant level", I'm guessing it's the sensor.
So the springs go on the engine side, correct?
Awesome video, surgical extraction of the thermostat was explained in simple, easy to do steps. I'm sure this has helped a lot of people. Keep them videos coming! I just bought a 94 E36 and it is overheating, takes a few minutes of driving to overheat, looses a lot of coolant, but there is no visible drip, just hissing from the heater core hoses area. Would you share your thoughts on this? Thanks
Typical thermostat failure.
I have the same problem on my '96 328i.. The last time I replaced the thermostat was back in 2007, when it overheated.. If you fixed it, what turned out to be the problem in your car? Thanks..
JC, I'm back to report that the underlying cause of my overheating was a broken heater hose flange at the firewall.
This caused an overheating event that busted the cylinder head gasket. Upon removal of the head, it was evident that the gasket was busted on cylinders 3 and 4 on the passenger's side. Further inspection showed several spots of pitting on the mating surface of the head, just over the bad head gasket areas. I wound up replacing both the head and the gasket and while at it, replaced all of the other main components of the cooling system. The car is running good now. I hope your luck is better than mine. Take a close look at the pipes under the intake manifold and particularly at the heater core hose flanges at the firewall on the driver's side. These 3 flanges are plastic and get brittle over the years. They break and leak coolant that comes down the firewall, just ahead of the pedals. This is tough to see, especially if it is a small leak, like mine was. With luck, just replacing the flanges will do the deed.
(all 3 come joined in one piece that bolts against a mating piece on the firewall, don't forget the gasket). I had to take my intake manifold to access the area, no fun, but while there, I replaced the starter as well and all of the hoses that run below the intake manifold, which became nicely exposed.
I can't find thermostat on BMW 323is
Ek het n Hyundai atos prime 11cc het termostat proebleem gehad en dit geknip maar die car word nog warm.dan gaan die elektriek fan aan die kar se engine loop nie koeler nie
hey i replaced the thermostat an put a new waterpump in an bleed the engine on my 92 e36 and it overheats any thoughts???
E36s are the queens of the overheat cause a blown head gasket. How did you bleed the system. An incomplete system bleed can result in overheating. Also trying a system reflush. They sell kits at autozone. Check your fan clutch for cracks on the blade and strange noises. Thats another possibility. Check your thermostat housing for cracks. It may also need a good cleaning. Also the the gaskets thermostat and housing need to be seated right to create a good seal. Thats just about all i can think of off the top of my head but i hope it helps. Ive dealt with tons of e36s especially overheating problems and these are the ones that i attended to fix my problems.
It can't be a 32 degree thermostat. 32 degrees F is the point where water freezes. Even if it were 32 degrees celsius, that's 89.6 degrees Fahrenheit, which is still too cold. My guess is that you bought a 92 degree celsius thermostat, which translates to about 198 degrees F. I use an 80 degree celsius in my E36 because BMWs run so hot, but I live in the SW.
You are correct. Misstated thermostat opening temperature. However, thermostats are available with multiple temp ranges.
thank you amazing
Is it really necessary to torque the bolts when putting them back just as long as they are tight?
To my understanding it isn't i just tightened to tight on all the bolts and i haven't had any problems. Now when it comes to things like the head gasket and valve cover gasket torque will matter greatly to create a good seal. Hope this helpped!
+Dennis Rawlette Anything that bolts to the engine is pretty important to follow torque specs. Snapping a bolt off in block or stripping out threads is not fun. Also gotta make sure the gasket is fully compressed.
Does the coolant need to be bled after this job?
yes everytime you empty the rad or remove a hose
i have a '96 328is. in one of the comments below, you mentioned that thermostats are cheap parts. what about the radiator or the water pump? are those parts pretty cheap as well or more costly? do you know where i can find this info online? my car is currently overheating and using a lot of water/coolant. so i have to pour water into the radiator or water pump thing (sorry, don't know much about cars). it is fine if i drive it short distances but if i drive it longer distances or just get stuck in traffic, i'm screwed because it overheats which i know can lead to a cracked head gasket (right?) if it overheats often enough. and i know that THAT would be a very expensive to fix. anyways, i don't know if my problem is that i have a leak OR if my thermostat or water pump is broken which is causing the overheating? any help would be appreciated. thanks :)
alypaige88 if you're losing coolant and having to replenish then you obviously have a leak somewhere that needs to be addressed. And that could be your only problem since a leak will allow air into the system preventing the coolant from making its rounds and cause overheating and/or no or low cabin heat.
First thing i would check is your radiator cap. If its bad and doesn't form a seal you will lose coolant. Check your radiator lines for cracks and liquid on the outside to identify possible leak areas. It is quite possible you are leaking coolant into your exhaust manifold if your not seeing visible leaks on the grounds. You may need a coolant reflush to clean the system or maybe you need to bleed the coolant system. Air in the system can cause your expansion tank to explode (learned from experience) or excess heat to enter the car. Dont suggest driving the car when it over heats can cause the heads to warp and a blown head gasket (also learned from experience). Hope it works out!
what kind of coolant is recommended for a 1995 325i e36 non m3? just bought one last night
Look in your expansion tank. If the fluid is green, then it's just regular coolant. Don't bother putting BMW coolant in it unless you flush the whole thing, first. If it is more of a blue color, then it is the special BMW coolant that you can get from the dealer. Unfortunately, you pretty much have to get this coolant from the dealer at $20+ per gallon.
BMW Repair ahh okay i see thank you, one more question though, every gauge on my cluster works except the coolant temp. i pressed the temp button and it said -35 F. A.C. works fine however the heater doesnt.. could it be the thermostat? ive driven this thing over a 100 miles the first day i got it and it ran fine and still is.. i just want to get the gauge fixed because i know the cooling system is a big thing with bmw
So there are actually two different systems on the e36. The temp button will give you the outside temp. the sensor for this is located in the left wheel well and often goes missing. it's not connected to any of the other systems and not important.
The Temp gage on your instrument cluster is, however. There should be a metal sensor screwed into the side of your radiator. (You can see me install this sensor into my new radiator in my vids on the topic). Chances are, this sensor is bad. I'd try replacing that... but note that doing so will result in the loss of some coolant. Good luck!
surryj Also, If this sensor is bad, your aux fan at the front of the radiator won't switch on correctly. This could lead to overheating.
BMW Repair alright then. ill change it when i get my next check and let you know how everything goes. and thanks again i love your videos
Very cool

Did tou really mean to say 32 degree? Lol i'm pretty sure you meant to say 92 or maybe 82 degrees.
32 degrees Celsius I think
300's&350's 32 °C is 92°F so I don't think so
That's what I said I can't find a 32
why did you replaced it how did you know it was broken
engine wasn't staying cool, engine will get hot without rad fluid, duh, if thermostat sticks than it cant open to cool the engine.
ok thank you i asked because i dont know
no problem
There was actually nothing wrong with my thermostat. I replaced it when I replaced my water pump because it's a cheap part that's easy to replace if you're already draining the coolant.
To better answer your question, there are two ways the thermostat fails: stuck open or stuck closed. If it is stuck open, your car will take a long time to get up to operating temperature (and may never read 12 o'clock on the temp gage). If the thermostat is stuck closed, the car will likely overheat. To figure out if it is the thermostat or some other component, try to squeeze the hoses on both sides. If the thermostat is stuck closed, one side of the hose will be under pressure. You will not be able to squeeze this hose. On the other side, you will probably be able to squeeze the hose slightly as the stuck thermostat won't allow the coolant to pass through freely.
+BMW Repair could u give me some advice please? My car gets to the 12 o clock mark when i drive in the city. When i go on the highway, the temperature drops to the left side(blue, cold area). What could this be? Does the coolant level has something to do with it, or is it the thermostat?Thanks in advance, have a nice weekend
👍🏿👍🏿
cool story bro . ..
