P38A Dumping coolant

tomcat59alan · Aug 16, 2017

After a crappy hour at the dentist I returned home to find bitch dumping its coolant on the drive. I didn't have much time to investigate as I had an appointment elsewhere but it seems to be coming from the metal pipe that connects the heater pipe to the engine block below the thermostat housing. So its either the retaining bolt come loose or the securing bracket sheared from the pipe. It seems to hold water and pressure until the pipe is moved. Tomorrow will tell, anyone think of another cause bar the o ring.

Hopefully the pipe isn't rotted through like mine were?

Missing bolt is M6 X 18 mm Alan.

M6 X 16 or M6 X 20 are standard which we keep here in stainless, 18mm is a bastard size.

Any hoof-prints in the lawn to track 'em? Sounds like some cowboy has been at it.

Nope standard size and that is the correct call up. M6 x 18 can be had anywhere.

Seems to be available as you say, but our local fastener suppliers say it's a 'non-standard' range, they don't stock it and neither does our other supplier, but plenty on the web.

Yep i would be surprised if my local fastener supply did not have them. However 20 mm down to 18 is not a big deal. The correct part does have a thick washer attached. https://www.rimmerbros.co.uk/Item--i-LR009113

Looking at some of the DIN fastener tables, 18mm is in brackets as a non-preferred size, which is probably why we've never used it, but availability is OK.

We don't actually use 16mm either, but we have a draw of them in the bolt rack!

This pipe hasn't been touched since I bought the car in 1998 guess it was just corrosion holding it in. All sorted now, sorry I couldn't reply earlier as I was in North Wales picking up the o ring and a few other bits.
