BMW e46 3 series Coolant Thermostat replacement

[@michaelsalazar6868]

I just put an electric fan like how you have yours and my fan doesn’t turn off even when the car is off, so how did you make yours work

[@basileczajkowski3236]

So replacing the thermostat doesn't require draining?

[@HansGarage]

Thats right!

[@basileczajkowski3236]

@@HansGarage That's a relief However is whatever leaks of any concern? From the vid the amount that spilled doesn't look alarming. Or should I top it off?

thanks for helping

Hi Mate great Job as always, 😎 but i highly recommend you to check your belts cause coolant can damage belts , or better replace it as soon as possible if you don’t wanna have a cracked belt on the street

[@HansGarage]

Changed my belts not too long ago and forgot to mention that this would be a good time to. But I did have a video on those as well!

[@dvtv4629]

Did you fix the airbag light

[@HansGarage]

I have a video for that. kzbin.info/www/bejne/r6vXYoGNetiFj9ksi=sk9yiKf6SOD6ufaS

[@dvtv4629]

Ive cleared my codes but not the airbag on its own. Ill try that next time

[@Sebastian.t123]

Hi Han! Did you drain the coolant first? And if so, was it hard to bleed the system after refilling it? Do you need special tools for refilling and bleeding?

[@HansGarage]

No need to drain... please watch the full video I explain it there.

[@Sebastian.t123]

@@HansGarage I did watch it. I just expected more coolant to come out where the thermostat comes loose. I guess there’s not much there because it’s the top of the system? Anyway… good video. Thank you!

[@HansGarage]

@Sebastian.t123 sorry I got mixed up with a different video lol. Here's a video you should watch kzbin.info/www/bejne/Y2XJemeXnZ6hmqs By design no need to drain the coolant at all if you are doing only the sensor!

[@Sebastian.t123]

@@HansGarage Thanks again mate. My e46 is giving me a P01619 code. So im looking to replace my thermostat before it fails completely. Only thing holding me back is the need to drain, refill and bleed the coolant. But i understand that’s not necessary. Biiiiiig relief. Thanks for replying, your vids are very informal so im happy i subscribed.

[@HansGarage]

Yea, thermostat will spill a little bit and just need to make sure the lower hose is upright. I would make sure to have a draining pan underneath to not make a mess!

[@dvnnix1234]

Before this fix did you lose coolant like crazy? I just changed my fan clutch it sounds better and starts better but still overheating

[@manliocicchelli8763]

Perchè non installare un termostato con apertura anticipata a 95°? Di serie monta sicuro uno da 105°

[@MrEegoy]

i can not find thermostad with 95..please inform the link

[@dvnnix1234]

It’s fine when idle and can stay in operating temperature but when driving problem starts smoke coming from hood

[@HansGarage]

You definitely have a leak somewhere. I would replace lower hose, usually the weak spot. I had no leaks prior to my issue

[@dvnnix1234]

@@HansGarage yea the smoke comes from the bottom and is just steaming hard and coolant is trying to cool engine down. Smoke come straight from the bottom towards coolant cap side

[@dvnnix1234]

@@HansGarage I can even rev on idle and it will remain on operating temperature till I start moving and also when I open the hood it’s coolant spills on the overflow area it’s not too much but noticeable easy to call condensation but idk

[@HansGarage]

@Dvnnix yea... you definitely have leaking issue. I would check lower, upper and even the coolant reservoir tank

[@dironizareyes596]

Hey Han! Do you have a tune on ur Ecu? And if so who installed it?

[@HansGarage]

I do not. These engines prefer not to turbo since they have very thin walls

[@dironizareyes596]

how many e46s do u have??? i have a 330ci for the summer and a 330 xi for the winter. is your automatic??? i swapped a 5hp19 tranny from a 2005 325I and swap the tcu from a 2001 325i. The 330ci stock tcu sucks the tcu from the earlier model are more aggressive. I downloaded a tune from a youtuber and the car has a nice pull now. These motors are build very well i have 260k on my other 325 and 230k on my 330xi and theyre bulletproof.

[@HansGarage]

@dironiza reyes I got 2 but total I had 4

[@dironizareyes596]

@@HansGarage no man get a tune dude!!! These cars can handle 400hp trust me . This is hubby here, bro we gotta link up I be in north Bergen some times. I got a 2003 330ci with destroyer gray paint job, dropped 2” on 19 m3 csl rims and mtech2 front with carbon fiber splitter and a small rear wing

[@HansGarage]

Lets!! I want to see

[@sbrave]

2000 328ci, temp gage recently only goes to a little above the 1/4 mark even after warmed up and driving. Not leaking any coolant. Sounds like the thermostat is bad?

[@HansGarage]

Yea that was my issue I had with my thermostat, I'd do water pump and thermostat at the same time for preventative maintenance if you haven't done so

[@petarbaleta5514]

Is this 328 e46?

[@HansGarage]

330xi

Oring tube change before reclose.

[@blackpassenger]

yo, Han, I'm about to replace my waterpump. it finally took a dump after 23 years. should I replace my thermostat too? I replaced it back in 2016, about 40k miles ago. what do you think?

[@HansGarage]

I say might as well if you are doing the pump for preventative maintenance. FCP euro baby!

[@blackpassenger]

@@HansGarage Sou da ne. Yep. cant do fcp though, i dont think they ship to japan.

[@HansGarage]

I see...

[@chrisyo295]

Hello. After replace water pump and thermostat my temp gauge goes to red while driving about 60 mph and i slowdown and temp gauge comes back to normal. And i have the obd2 conected and temp reads normal. Any suggestions will appreciated. Thank you. Great video

[@HansGarage]

Wow... then it must be those 2 other sensors under the intake manifold

I use blue driver

[@Salken3]

Very good👍

[@jeffk5386]

I noticed a big piece of your water pump pulley missing I hope you saw that and replaced with a better metal one like I did

[@HansGarage]

Yeap the metal one is the way to go! Same with steering pump pulley
