Just what i need at this time of year!
All was fine till last weekend when it went a bit luke warm then stone cold, seemed to work for a minute but not very hot then ran out of heat....dials say 90deg and warms up ok.
Plugged in vcds lite today and engine eventully gets up to 86-88 deg, is this warm enough?
Pulled both hoses from the matrix connections and ran hose of outside tap through in both directions and seemed to flow ok so not that.
When i put hoses back on and ran the engine up there was no water flowing up from cylinder head feed, i squeezed the top rad hose (under reservoir) and got a glug on the return side.
Should there be a constant flow through the matrix, if so the water pump must be knackered, otherwise i guess the thermostat has gone?
Strange that it was working fine one day then suddenly stops the next, can they do that?
It had a good flush 2 years ago when it was cold for the first winter and made a massive difference, and i changed the coolant again back in october 2012 so i just don't understand how it can suddenly pack up???
words of wisdom please...
