Water temp feed

[.Mark]

So you may realise I've been poking around under the bonnet

Bled the clutch, re-routed the washer hose so it avoids the water rails/exhaust manifold and hopefully won't melt again, and on the other side I've notice a cable/tube with wire wrapped around it that runs from alongside what looks like the bottom rad pipe and under the front cover, up and under the drivers side airbox (suspiciously close to lots of heat) and in to the inner wing behind the clutch reservoir.

My guess is this is the feed for the water temperature gauge? While I'm in the re-routing mood I suppose it could be moved somewhere that is less susceptible to heat and might give a truer reading especially in traffic.

Question is, have I identified the correct cable/tube, and if so, is it a cable or a tube and could it be re-routed?

Yep, that's the (badly sited) water temperature feed. Unfortunately it is actually a capilliary of some sort and very difficult to move without breaking.

I'd leave it where it is...

^^^^^^^^^^^^^

Wot he said, be very careful the capillary is very delicate and doesn't take to kindly to being bent to a different shape.

You have been warned...........................Twice.

Warning heeded.

Thanks chaps.

Flippin' inspired installation eh?

[Tanguero]

Yes - you do need to be reasonably careful with it and avoid anything other than gentle bends, but I moved mine without any problem. I shifted it a little so it would run along the water rail and cable tied it to that. I can't in all honesty say it has made the least bit of difference to the temperature reading, but at least the capillary isn't flapping around and vibrating.

Mines all nicely cable tied up, sounds like a similar route to yours actually. Wonder if I could perhaps insulate it?

[Mr Cerbera]

Seems a bit mad to insulate it from the item it is supposed to be measuring...

Thought it would measure the temp at the radiator not the red hot steaming engine block and trapped heat?

[Mr Cerbera]

Well, I guess if you've got a red-hot steaming engine block then there's no water in the radiator to measure abyway

Just kidding !

During the resto, I re-routed mine through the o/s front wing and along the front behind the rad. I didn't do this just to attempt to achieve a more accurate reading, but to improve the appearance of the engine bay by having one less cable strapped to something.

The reading was lower than the higher temps that are common to Cerbs. Whether that was due to the cable re-location or the new rad, pipes, hoses, uprated stat and water wetter, who knows...

Or maybe it's being cooled down by the in coming air ;-)

Mine is also tied to the top of the water rail. It's still too close to the manifolds imho but probably the best place for it.
