Run-on Pump

[Ex-Galaxy person]

This post is related to my current posting about gradual coolant loss, http://www.fordgalaxy.org.uk/ford/index.php?showtopic=15419, but is a separate question.

 

Whilst searching the forum today, I came across mention of the coolant run-on pump that is supposed to keep running for a few minutes after the ignition is switched off. I have never heard this running on my Gal. Whilst investigating the other problem (in the dark, with a torch) I looked for this run-on pump and couldn't be sure I could see it, although I could see two smaller pump type devices on a bracket behind the fuel filter. The pipes going in to these components were only about 10mm wide - didn't look man enough for the coolant system - neither did these components. I didn't have the light to be able to trace the pipes and see where they went either.

 

So, I dug out my 2004 copy of TIS and looked up the cooling system - which makes no mention (at least where I looked) of a run-on pump (I don't think TIS is that easy to navigate IMHO). All the posts I've read on this forum where run-on pumps are mentioned came from people with Mk2 Gals (PD engine). I've got a Mk1 with the earlier 110BHP engine.

 

My question is this: are the Mk1 diesel Gals supposed to have a run-on pump, or this this just the Mk2s? Sorry to ask the dumb question - when I get to Saturday I'll take it apart in daylight and I'll probably see it - even if it is there, the engine bay is as silent as a grave once the ignition is off - even after a run, so it must be n/s.

 

One diagnosis of the coolant leak is a failing head gasket - which in itself may be caused by the run-on pump not working (if it's supposed to have one) - hence this post!

 

TIA

Hi Phillip,

I had a look at my mates mk1 at work today, i couldnt see the run on pump either but it was dark in there less room than the mk2.

Folks - just thought I'd confirm that there is no run-on pump on the Mk1 TDi (non-PD diesel engine). I had a good poke around in that area at the weekend, followed all the pipes around with my hand and it's not there on mine.

 

Haynes Manual and TIS makes no mention of it either, so I'm 99% sure it's a Mk2 component.

 

Thought I'd share this.
