1981 Mk1 golf Cabriolet

I require a relay layout diagram  to identify which relay the low coolant level alarm uses

Alarm is always on
I use 50% antifreexe mix

Any other suggestions would be appreciated

THe 81 didn't have a low coolant relay persay.  The Coolant tank doesn't have
a boss for the Level sensor that a mid 80's-90's Cabriolets had.

My mistake I was taking to a colleague about a Mk1
What I have is a 1984 Mk1 cabriolet.
Low level coolant alarm always RED,
Fitted a new probe and tested with 50% antifreeze, no change.
Checked the Heynes book should be Relay 18 but the relay in that position operates the windscreen washers?
Only one relay on the top bank
See actual relay and photo, Numbers on relays do not match anything I have

well on my 90's cabbies, the relay is numbered 42 not 43, I didn't ever see a 43 labeled relay…  But the relay is located at position 1 in the ancillary row on top of the fuse panel

Hi Guys VW

1984 MK1 Cabriolet GTI (UK Model)
VIN WZWZZZ15ZEK025780

1. Still struggling with this low level coolant fault

Tried a new relay on the position noted above (left of 76A) did not work, had a 50% mix in test bottle  in, do not see a fuse in that circuit ??.
Thoughts?

2. Next when trying to fault find the Generator Fault light came on?

Fuse number?
Relay number?

Thoughts

See photos

Any help appreciated

Regards

On your coolant level probe, clean the points or contacts, as if they are calcified or corroded they can cause spurious issues.  

when covered by 50/50 blend of Water to a/f.  there are at like 68 ohms.  Not a short but not an open.  

too much a/f to waterand they will not read right.
