Those engines of that era were bullet proof, once had a 325i and the expansion tank on the side of the radiator exploded on the M62, I drove it home with the temp pegged at maximum, fitted a new radiator and drove it for the next two years with no problems, one of the best cars I have owned.
You ought to have seen some of the destroyed water pumps I changed on taxis over the years. I thought cab drivers were the only one's who could proper bugger an engine ...but I gotta say Alan that's the worst i've seen lol!
The plastic fan shroud is missing on that one - and I would be replacing the viscous fan coupling as well. The grotty old one fitted is almost certainly the original. The pump wasn't the factory fitted one but had been in there a long time. The orange coolant needs draining, flushing and replacing with the proper blue stuff ideally. The 2.0 M52TU engine is a tough old lump.
I had a bwater pump bearing on one of my E39 M57D30s collapse like that. Fortunately being a common rail diesel the engine only got very hot and didn't overheat. Getting that K&N filter replaced with original spec filter housing and ducting would improve the engine as would getting the fan shroud reinstalled.
Allen A other great video mate I have never seen a water pump so badly worn miracle the engine is fine must be a dam good engine BMW have got something right for a change Phil in stoke
I've just changed my water pump Alan on my E36 with the 6 cylinder 2.5, I did it as a matter of course as I've changed the condenser and a/c pump & receiver dryer, they are a good engine and I love the brand, love watching your videos bud you and Moni do. 👍
@@alan4x thanks for putting my mind at ease over the dpf on my 1.6 diesel which does very little miles on last night's live chat, your opinion is very much appreciated
That shocked me. The amount of 6-cylinder BMW engines that I have seen with water pump problems, i.e. The impeller spun off the end of the shaft, has always resulted in a new engine, because it is pointless changing the head gasket. The heads will not only crack, but warp like a banana, and so do the blocks. Have you ever tried to straighten a banana? I grew to hate BMWs and said that I would never buy another one as long as I live. Now BMW has problems with the diesel engines having the cam chain at the rear of the engine and unserviceable until it all goes wrong about 90 - 100k miles, then it's a new engine, Thanks BMW... NOT!
Mine overheated and dumped its coolant twice in the 10 years I had it. Once due to a failed viscous fan and once because of a stuck thermostat. Both times the engine and head gasket were fine.
It never ceases to amaze me how drivers can neglect and abuse their cars...even high-end makes like BMW. That oiled K&N type air filter isn't doing the mass airflow sensor right downstream of it any good either. Odds are it's gummed with air filter oil.
Next step - clean the leather drivers seat. Red is much nicer then black stained red! I think with BMW’s you need to set the heating to max and fan/blower to low as you fill the coolant to avoid air locks. There is definitely a set procedure. Great video
One problem with these is that the viscous fan clutch fails over time, but the problem is masked because the air conditioning pusher fan also acts as an auxiliary cooling fan. Most of the time it copes, but get stuck in a traffic jam on a really hot day, and you end up boiling the coolant. Ask me how I know this!
I'd definitely do an oil and filter change at that point as well yeah! I'm just a DIY hero though so I don't know if a professional garage would deem it necessary.
I had a Jag x type and the water pump just exploded on the road but the engine was ok on that just luck sometimes made a Wright nose when it went it was a Wright job changing that on a V6
Hi Alan see you were live on 27th July I know it sounds cheeky but what is your daily vehicle now old Mercedes van went to the scrap yard beginning of this year thank you doing videos and like it when you do lives and you try help people to fix the problems there vehicles?
No expense spared there eh Alan with that Key Parts water pump 😝. I guess you weren’t too confident in it living to die another day😂. Bet you were glad to send that down the road!
that's the worst worn water pump I have ever seen. that must have been rattling away for ages. did the owner not hear that rattling?oh yeah, is the nissan elgrand in the used car lot for sale?
Cream job alan , could be worse , could have been a pile of crap to work on like more modern poo we have to do , hope you bought the 21.5mm socket I told you about a while ago , used mine yesterday swapping a full set of the rubbish wheel nuts on a 2019 transit custom, makes the job so much easier 👍
Any stuck water - lift the front up. The fan itself can be deleted. 153k and it’s high time for a new water pump. This is the M54 mill. Possibly the best straight six BMW ever built.
Hi Alan, I have a 2015 MK3.5 Focus ST 2L TDCI , keeps going in to limp mode with "engine service now". EGR valve recently replaced but i'm still getting the below codes. I am all out of ideas! Is there anything you can suggest to check/clean/replace etc? P1102 - MAF Sensor In Range But Lower Than Expected P0069 - MAP Barometric Pressure Correlation P02FA - Diesel Intake Airflow Position Sensor Signal Above Allowable Range P003A - Turbocharger Boost Control A Position Exceeded Learning Limit P02ED - Diesel Intake Air Flow System Low Airflow Detected- Actuator Stuck Closed
I’ve not got any experience on these engines but I reckon you need to free off the stuck actuator in the air intake system. Is there a throttle body or similar? This might be causing the other problems.
@@thecolneranger1588 yes i have thought about this but i am unsure whether it's the throttle body it is relating to. I just need someone who knows these engines inside out to confirm tbh
You need a garage that has an AUTEL diagnostic machine. It will be one of the maf sensors there are 2 one on the intercooler one on the air filter. Same problem with transits. Reading codes is no good you need a machine that will reset values etc show u live data
hi steve, i would before anything check your turbo intercooler hoses for air leaks, the one down by your alternator can get cut by the fan belt and check all your vacuum pipes which many are all around the egr valve...had a vacuum pipe been left off
@@alan4x thank you so much for finding the time to reply to me. I will check the hoses. The vacuum pipes i'm 99% sure are all attached as i went back over everything after refitting the new egr and connecting everything back up. But i will.checl those again for sure. If all the above does look okay, what would be your next step/check etc?
Lady owner = kerbed wheels, never serviced, no wiper fluid, just drove! A girl I know said to me once that a car is serviced at the MOT centre when its being mot 'd
@@alan4x I saw one of these the other day on a 3.0 Z3, exactly the same. Luckily he didn't cook it, probably a good idea people change them prophylactically.
12:55 WARNING!!!!! .............DO NOT DO THIS !! IF a head is cone that would have blown the coolant out of the res/rad, when the engine was cold! Actually you didn't have that engine hot or/and there is most likely air in it. You know you can boil water and coolant under 0c* when you lower the pressure ? And that you can raise the boiling point by raising the pressure? And thats why there is pressure reading on the cap for over pressure it blows out and so there is no need to you burn your self... The Temp.meter (at dashboard are cone for this reason now days)don't normally show how hot coolant is and its done so as they run hotter then 100c! And when they did "show temp" it was a lie for the ones that didn't know over 100c* is OK for cars coolant! So when you undo the rad/res cap as the system is hot. The pressure lowers in the closed system. ....and guess what? ...the coolant boils and "the water" raises out of its place. and may burn you! Anyway Rant away damn thats bad bearing and clad that fan didnt hit the rad ;)
"it is an American woman that owns this car. Need i say more?" 😂😂 I have a feeling where this is going to, but not totally yet, so enlighten us Dutchmen with your analysis 🙄😁
we have a lot of americans rent hire cars, many of them never seem to notice the temperature gauge or the engine screaming at them when its ran out of oil or water lol
this is a m52TUb20 engine.... those are REAL BULLET PROOF! the m54b22 is a piece of crap IFF she blows coolant! how bigger the m54 is? the more risks they have.. the m52TU types are the rarest because they are NOT LONG deliverd in bmws..

i wish i had filmed the noise..it was horrendous
Im suprised it hasnt been overheating for a good while. There is a lot of rust on the front that could do with treating before it causes probplems.

Thinking the owner got lucky.
Should the oil be changed once an engine has run hot? Preventative maintenance?
I'd definitely do an oil and filter change at that point as well yeah! I'm just a DIY hero though so I don't know if a professional garage would deem it necessary.
it should have an oil change, depends who it paying for it
Enjoyed this one 👌 alan nice to have something different just saying from North of Newcastle 👍 😀

hi stephen, i don't have a vehicle at the moment, i am using company cars to get about but when i get a car or van i will make a vid for sure
On an engine that overheated would it be advisable to do an oil & filter change?
yes but if the owner is not paying then it won't get one
@@alan4x I appreciate that. I was just asking for your Confirmation that it would be advisable.
