Water temp.

Post by **kentishvanman** » 04 Nov 2018, 16:30

Hi,
My temp gauge needle always sits just below the normal mark. Heater on or off.
However on last journey I drove 100 miles (A road) = as normal.
Stopped for 4/5 hours.
Drove 50 miles (A road + motorway) = as normal.
Stopped for 1 hour.
Drove 35 miles (Motorway) = needle now sitting above the normal mark.???????
Water level same as it was when checked 400/500 miles ago.
Could this be the start of a problem?

When was the last time you had a coolant flush out?
Mine used to sit in that sector of the gauge, tho since had pipes replaced & flushed out etc, the needle mark always sits below centre (unless a very hot day or going up a large hill).

When I bought my first car (Morris Traveller) I said to the bloke I bought it off that I was going to fit oil pressure and water temperature gauges to the car. He told me not to as they were "Worry Meters".

Lol, funny that!
To OP, in the VW handbook I gather for a temp gauge anything from say 11 o' clock to 1 o clock roughly is normal and if your fans are working correctly they should kick in anyway to bring the temperature down.

The sender resistance decreases with temperature. High resistance in a connection will result in gauge reading lower than it should.
