LITERALLY THE ONLY VIDEO & INFO THAT TOUCHES ON THIS TOPIC! Thank you bro ! Bought a mosselman thermostat and cooler thinking I had the cooler already🤦🏾‍♂️

[@KoseyM]

Comments like this pushes me to not stop! I'm glad it was able to help you out ✌🏾

[@nickbrestovansky8772]

Good work man hopefully picking up a 335ix with in the next couple weeks so i’m looking into all the basics now

[@KoseyM]

Sweet! From my experience, put money aside for injectors, water pump(mine is going, and fuel pump. Rumars are true lol. You'll love it regardless. Handles very good in snow as well!

[@bmws1krr340]

The x r great cars but if ur going to build go w a rwd less maintenance and cheaper on repairs

[@tazwinsulose]

Just bought a used oil filter housing with cooler hook-ups for my 2008 335xi. I found out that the only 2008 335's that came from the factory with oil coolers were the one's that had the sport pkg AND 18" wheels. Mine has the spots pkg but had 17" wheels from the factory (18" aftermarket now). This video was super helpful. Thank you so much.

[@KoseyM]

Im truly happy that it did! Also, if you were the original owner of the car, you could of gotten the oil cooler system installed by the dealer under warranty. Apparently a large group of individuals complained about the oil temps and were sorted out for it. Stay awesome!

[@tazwinsulose]

I'm at 136,000 miles. Those idiots won't do anything for me under warranty anymore. Lol

[@atlantajunglepythons1744]

@@KoseyM I never heard about that. I'm 2ndowner, @ 90k...probably not a chance to get one from the dealer. You bought an original one used? Do you know how thst compares to sn aftermarket upgrade oil cooler kit upgrade? It id hot where aI live, and oil temps run high

[@KoseyM]

You can probably ask but I'm not sure if they're offering that anymore. If you're in a constantly hot environment, I would suggest going aftermarket. Before you do that though, check if you still have the manufacturer warranty. Don't want you to lose that lol. Now, there's a few routes for this. Upgrade the internal thermostat or upgrade it completely, upgrade to a larger or dual oil cooler set up, and or do both. You should see a temp range between 210-240F depending on how you're driving. Used to hit 245-250F on a constant with the original setup. Look into the Mosselman Thermostat(I have w/my n55) with a CSF oil cooler(looks stock but is much larger). Im still running a stock cooler on my new car and the temps already dropped 10-20F Hope that answered your question. If not, let me know!

[@atlantajunglepythons1744]

@@KoseyM thanks, great answer. Gives me a place to start looking. My temps are like the ones you used to have, and I'd like to drop them 10 to 20° (it's a bit scary watching the needle climb while sitting in traffic) so I'll be searching for I guess an aftermarket solution. I need to try to keep this reasonable, but better to pay for cooling parts than a whole engine

Can you provide the link to the kit you have? Im trying to retrofit an oil cooler on my 07 335i as well. Would be much appreciated!

[@denisv1967]

thanks for showing your instal , i just bought an aftermarket cooler looking for the tips. btw when you change your oil will you be disconnecting the hoses and drain

[@KoseyM]

Glad it was helpful for you! I did not but if you'd like to, there's no problem doing so. It's just extra work

[@the3VIL]

Can you include links to the oil cooler housing and oil cooler?

[@hunterdavis4753]

Where did you get that bracket. Drop the link pleaseeeeeee

[@AlexAlioglu]

for anyone doing this today when you take the gasket off it will be crushed onto the oil filter housing so don't get scared if your new gasket is too thin that will get crushed onto it as well

[@jimmytv691]

How much all cost bro ? And pls paste the url from where u buy coller and etc

After I've taken off the intake manifold about 5 times now, its only 15 min now lolololol, The more you do it, the quicker it gets :S

[@amariodom4858]

where’d you buy that

Is the n54 cooler the same for n55

[@albertperez1050]

Where did you get the after market adaptor

[@nickgrottola5499]

Looks good, I’m thinking of doing mine next weekend and I think I basically bought the same kit as you. For the mounting bracket did you have to do any extra fabricating or did you simply just bolt that bracket in. Any tips would help thanks

[@ltdasilva93]

hey brotha, that blue adapter piece that comes with the oil cooler, does it thread directly in the oem thermostat or is it kind of a insert and tighten with the bolt style? Did it use copper rings to prevent leaks? I bought a used housing and replacement gaskets but want to buy an ebay cooler like this one. Where exactly do the braided lines leak, and how is it holding up so far?

[@KoseyM]

Hey! The oil cooler is fine. The adapter on the other hand is a no go. It threads in but does on seal the best. Might as well go with a different brand

[@overboostedgarage8744]

Did you have to swap the sensor that plugs into the oil cooler housing ? The plug on my non oil cooler is different from the new one I got with oil cooler fittings

[@KoseyM]

No, I didn't have to

[@theowner3947]

do this kit fits on 08 bmw 535xi bro ?

[@ddanter30]

Perhaps I missed it in the video somehow but which kit did you purchase for your car? I have a 2011 coupe that did not come with the oil cooler however I liked the cooler kit with the braided lines + bracket that you have for your car.

[@KoseyM]

It's one off of Ebay but I recommend getting another brand. The fittings that attach to the hose gets loose over time but definitely get one with braided lines

[@ddanter30]

@@KoseyM thanks for the advice and for the good video!

[@KarenchikJan]

Great video and very helpful! I changed the oil filter housing gasket and while disconnecting the upper radiator hose, I broke the rubber o ring. I can’t seem to find the o ring on sale separately. Would you have any idea how I can obtain this without buying the entire upper hose? Thank you

I hope this helps

[@KarenchikJan]

Thanks brother! I saw this, but are you sure it is the same size? The one linked is only 29.9mm. The side of the upper hose connecting to the oil housing seems much wider.

[@emilyhofland8219]

I measured the part and dug a fitting o-ring out of a box of o-rings... Something necessary for any dyi tech. Also. O-rings that aren't so easily replaced actually don't cost that much. Call the dealer, you might be surprised. ... I think it was $3 for my oil cooler o rings.

[@jeffireland1941]

if I buy the oil filter housing and the oil coolant setup with hoses used from a later motel will it fit a earlier model?

[@KoseyM]

It could vary between models. For example, a 5 series N54 or N55 may have a different configuration than an e90, e92, or e82 with the same engine. But generally yes, just double check

[@Dude-yo5ec]

Hey 👋🏼 where did you get the blue part? Also did you use the hoses and connect them to the stock cooler?

[@KoseyM]

I think you're referring to the AN fittings. They came in one package but if you want to buy them separately, look for AN10 fittings. This car did not come with an oil cooler. In 2008, if you did not have sport package, you didn't have an oil cooler. The oil cooler came from ebay

[@bigstep9276]

I do like it without the bumper also

I did purchase this from ebay but advise against it. It leaks after a while

[@nikhilsoni1773]

Would I be able to just buy a BMW Oil Cooler Thermostat and add it? Or would I need the entire thing with the oil filter housing

[@KoseyM]

You should be able to just buy the thermostat. Just make sure you get new gaskets and hardware along with it

[@emilyhofland8219]

Oil cooler already has a thermometer. Its the bottom plug. The thermostat isn't anywhere near the cooler. Its on the passenger side, very bottom, just above the water pump.

[@Darkeiser.7]

I'm wondering if the oil cooler housing is the same as the n55 oil cooler housing.

[@KoseyM]

I believe it is the same housing

[@emilyhofland8219]

Check how the hoses run... That's the only difference I've seen in the coolers of the same generation.

[@GODISGOOD1916]

Apologies for the late response. What part is confusing?

[@GODISGOOD1916]

@@KoseyM the oil cooler fitting, its hella confusing, can't understand if it needs plugs or not, didn't come with any, theres like 4 holes in it, not sure, appreciate the help

[@KoseyM]

The protruding fittings on the "cube" portion is fitted into the bottom of the thermostat. The other two holes are where the oil lines plus fittings connects to. With that "cube" or "block" portion, there should be a screw that screws into the thermostat body. Then of course the oil lines connects to the oil cooler

[@GODISGOOD1916]

@@KoseyM thanks, jus wondering cus the guy at the shop doesn't know how to do it so I'm going to have to do it myself, So how does the cube hook up to the thermostat?

[@KoseyM]

All good. The thermostat should have two openings or holes at the bottom like shown in the video. The side with the protruding end slides in those two holes. It's then secured by a long screw. The size may vary due to the set up

[@matthewweisdorfer7757]

what did you do to replace the mesh?

[@KoseyM]

Apologies on the response. I took it off and left it open. Kinda ugly and non incognito

[@preludeonboost]

Hey man I got the same exact car 👌. I haven't seen many like this. What are your oil temps after the cooler?

[@KoseyM]

Highest temp I've seen is 225°. I have a leak at the fitting connecting to the housing adapter due to not having the 90° fitting attached. Other than that, no issues with the cooler itself. I'd upgrade to a "branded" only to see if there's a huge difference

[@Alpha_apex]

Kosey so your saying the straight fittings you have on the adapter aren’t good to use?

[@KoseyM]

From what I'm experiencing, yes. The 90° fittings are the proper fitment

[@Alpha_apex]

Kosey but didn’t the kit come with the straight fittings? Are you sure it’s tightened properly? I’m just asking cause I think I have the same exact setup on the way and don’t want to run into that problem lol

[@KoseyM]

I tighten it as much as I could. I'd get an extra pair of 90° fittings(they come separate of course) if yours begin to leak. If it does not leak after a week or so, let me know. I'll double check everything on mine this weekend

[@MustafaKhan-ph5hl]

How is the setup running overall ?

[@KoseyM]

Pretty good but the fittings are good for a out 2 months then they leak. Oil cooler itself works fine

[@kingdennis3383]

What tool did you use to take out the bolts?

[@KoseyM]

Which bolts?

[@kingdennis3383]

Kosey when you bolt the Oil Filter Housing to the engine

[@KoseyM]

8mm(12 point) or e10 torx socket

Of Course!!

[@CN-lee]

are you experiencing oil burn? if so how mush does it consume per month?

[@KoseyM]

Not at all. Though I will be replacing my fittings because they are leaking. Highest my oil temps have been is 220°F. Oil has been full. I did loose some due to my valve cover leaking. Video of that replacement will come out soon

[@goclunker]

Change your PCV in the valve cover. If you are consuming oil, yours is blown. Its suppose to be a one way check valve. Mine blew air both ways ( new one did not) and I was consuming oil like crazy with smoke sometimes) $40 for a aftermarker pcv and alloy cap, all oil consumption stopped and zero smoke. Before someone tells you its the turbos, try this first

[@stevelee848]

@@goclunker PCV upgrade also stopped a turbo coolant return line leak, a valve cover leak, and an oil pan leak on my '07 335i. Building pressure in your crankcase is no bueno, best $40 I've ever spent!

[@famousmidnight]

You need the fender liner that vents air through the wheel well. otherwise, you just wasted your time.

[@KoseyM]

Had one installed at a later date but there were no significant difference in temps

[@goclunker]

I'm gonna chime in about one thing: I think the placement for the cooler is poor, hear me out. There is a giant plastic wheel well right behind it, there is really nowhere for the air to go. It would be better placed further away from the wheel liner near the front of the bumper, or if the wheel liner had a section cut out of it with say a plastic or metal grate to catch debris from the wheels. Sadly, dust and water would still splash in. I just don't think its as effective as it could be right in front of the plastic wall.

[@emilyhofland8219]

Why are you retro fitting an oil cooler, to a car that has an oil cooler? You do know that retrofit, means custom fabrication, right? Changing the seal, isn't a retrofit.

[@KoseyM]

The 335i/xi did not come with an oil cooler depending on when the car was manufactured and the package the car came with.

[@emilyhofland8219]

@@KoseyM but I watched you remove it... And the engine has the holes cut for it. It can't be just a filter housing. Cause you removed coolant lines from it. Was it just the small radiator that you were missing?

[@emilyhofland8219]

@@KoseyM damn, answered my own question. That's absolutely just a filter housing... Its weird they run coolant through it. That absolutely makes it an oil cooler. But with no condenser, just be the non turbo setup, yes?

[@KoseyM]

The only coolant line I removed was the upper radiator hose. The ports of each oil filter housing are the same. The difference is the "bolt-on" or "external"thermostat. That is why there are ports for the oil cooler lines on the new one and none on the original. This car is the non sport package which did not come with an oil cooler

[@KoseyM]

The non turbo, n51 or n52, did have a heat exchanger attached to the oil filter housing but not the same as the n54
