i put the old one back to the block, it fits perfect. but it's o-ring was not there.
for sure i dont want to take the manifold of again. that's why i stop, and find the solution. there is a gap from around 11 oclock to 4 oclock of the round circle.
i am not sure the oring seated well or not since the size of the gap is not small, that makes me very worried.
RTV silicone can be used in coolant system like this case?
thanks all | | | | |
If it was me I'd probably try and get a replacement because if it leaks you have to take the entire manifold off again.
Yes, it is very likely that the old one dissolved inside the block and the ORing was pulled along. When I pulled mine out the o'ring was still in the block hole and I was able to pull it out.
If the Oring doesn't seat at all around it will not hold coolant under pressure. I can't see any problem with using RTV but it probably won't work if there isn't a decent O'ring seating. The gap on mine was small, but it was a gap. In fact, I was afraid it would not work, but I took a chance and it did. If you look at the o'ring on the part I think you can see how far in it must go. The RTV could probably hold but I would think it would only work if it was only to help the Oring seal. I think there is probably some slight movement between the block and the part when things heat up, the part being plastic.
As a test you could fill the engine with some distilled water up to the level, if it leaks now, it will leak (but no guarantee that it won't leak when hot), or, better still, if you have some way of putting a bit of pressure in, like a pressure brake bleeder, you could pressurize the cooling system to a few pounds and see if it holds. | | Last edited by bob_bmw_101; 05-07-2012 at 02:17 PM.. | By mars on 05-16-2012, 05:07 AM |

where can i find that connector? | Doesn't it go to the heater core? http://www.realoem.com/bmw/showparts...63&hg=64&fg=15 You should see two fittings coming out of the firewall in the engine compartment. | | | | |
I just ran out and looked, on my 97 it connects to the heater core on the upper center firewall. It is plastic. There are 2 and it looks like one goes to the front of the car, the other (towards the right or passenger side is the one you want. It looks like it bends upwards more than the diagram shows. THe bend shown in the pictoral is actually bending upwards.
facing the car it is this one --> O O | | Last edited by bob_bmw_101; 05-16-2012 at 01:45 PM.. | By mars on 05-16-2012, 02:24 PM |

On my car it is just a hose clamp. They are vey available, even at local shops. | | | By mars on 05-16-2012, 03:20 PM |
The problem is the hose clamp tight the hose to the connector, but my connector is broken. | | | By mars on 05-16-2012, 04:20 PM |

This is an awesome how-to thread; thanks for putting it together! My daughter just brought home a '97 318Ti, but with 190,000 miles and zero maintenance history, the cooling system was my first point of concern. Looks tedious but very doable, given enough time.
Thanks again! | | | | |
+1, just finished replacing the radiator today! | | | | | Pelican has the Water hose Kit, listed for $150 too

Great write up! I was able to change the back of block plastic piece by removing the firewall compartment. I changed my oil in the process and in total took about 5hrs to complete!
So it's surely doable!
I have 66k on my 97 e36 m44 1.9 and seems the plastic already cracked before I got it because the person put some kind of crap all over the plastic instead of replacing it!
I was going through the losing coolant issues and couldn't figure out where the coolant was leaking towards the back of the block until I found this thread!
This site has saved me so much money in the 2yrs I've had my car!
Can't thank you guys enough!! Keep up the great site!! Thanks! | | | | |
Hi there, with the water pipe connector (11531743679) that fits on the back of the cylinder head, how long a job would you say this is? Or maybe, how hard a job is it. You say it's a b!tch, and when I looked at the access on mine, it is unbelievably tight. How easy is it to remove the cabin filter cover? Is this the same as the 'firewall compartment'?
The actual connector itself broke when i was 30 miles from home. I had to get the AA out. at the moment the hose is stretched onto what was left of the pipe connector (almost an inch was lost where it broke) So basically the hose could come off anytime....
The annoying this is that I suspect the local garage caused it. I had new rigid brake pipes fitted, and I know they had a hard time. The suspect thing it the pipes are only just behind this pipe connector. The AA guy thinks they must have levered the brake pipes into their clips, and put a bit of pressure on this part. Yes, It was obviously old, and dried out etc, but it looks like they've made it go even faster!
Any advice on fitting it would be appreciated, as it's been a few weeks now, and I'm either going to have a go myself, or go to the garage and see if they would be prepared to do a bit of discount.
BMW quoted this as 1.5 hours - which sounds quite quick?
But that is at £100 an hour labour + vat. Normally its £125 an hour, but for older cars it's cheaper..... | | | | |
its very easy to remove the cabin filter cover. 3 screws that's it. Although you can do it with out removing the filter cover, it is extremely difficult and expect some bruises on your hand | | | | |
