Once again I have to take my hat off to all who have tried to help me resolve this overheating issue ! Fanx !!  :y

I have taken a good look around the engine and didn't find what I was looking for ! -- the old peepers aint what they useed to be !!  8-)

After having a good looky looky around where the water pipes go through the bulkhead - I even tried to follow the pipework back to locate said valve - having no luck I did manage to locate what appears to be some selonid operated valve ???

Will get one of the kids to show me how to upload a photo of this asap so hopefully somebody can tell me i'm trippin and to looky looky behind the head or whatever  ::)

Will keep looking for this valve thou and --- no you can get a manual for this engine, Haynes dont cover it on a BMW diesel either !

THE BOY !  Do hope your wrong ! But from what I've seen on the site so far - u could be right again !

Tonight I was able to have a good look for this heater bypass valve and didnt find one, either it has been removed - or this model which is a 97 wasn't fitted with one - more likely I'm losing the plot altogether   :o

The mysterious selonid valve thingy turned out to be a water circ pump of sorts which was under the header bottle - doeasn't appear to be working with either the heater running on full blast ( which didnt really get warmer than a breath ) or the AC on.

The car was running for a good 30 mins and during which the revs were held at 3K and the header bottle topped off and watched for escaping exhaust gases. The car was held at 3K for a good 10mins after which the temp began to rise above 90 on the gauage. Didn't notice any difference in the level or any bubbles !

As the temp rose the water started to seep over the edge of the header bottle, it then slowly began to bubble and get warmer as the steam began to rise - the kettle was ready  :y

Hopefully this indicates that the water is being boiled off in the block and the head is ok ???

Would love to know what this pump is and where the best place to shop for it and a water pump ??? - Ebay ??? Unable to post pic of pump !

Would also appreciate any advise or pointers from somebody who has done a water pump on a td , other than get somebody else to do it   ;D  ;D

As said earlier, HBV is plastic valve attached halfway along the drivers side of rocker cover.  Waterpump is the bit the viscous is attached to.

Whip out waterpump and check impellors still there.  Do not use car, if the head is OK now, it won't be if you keep letting it overheat.

LOL ! " Whip it out ! "  :y

With a little bit of luck when it does come oot the fins will be awol !

The water pipe the runs along the drivers side rocker cover is a metal pipe that t's off to the bottom of the header bottle via a rubber hose ?? Cannie find this HBV !  :'(

What of the missing fins from the water pump ?? Are they easily retrived from the block or is a fishing expedition ? Time will tell eh ??  :-/

Will try and post the pics I have of the circ pump !  :y
