OK,. So fixed the water pump thanks to you guys..
Now onto a long standing issue.
This can happen after 5min, or not for an hour... Driving along, mainly on motorways, but can be at slower speeds, seems to be when engine under load like towing or going up hill...
Glow plug light flashes... Power drops to about 30%.. Quick ign iff/on and it clears... Carries on as normal.... May happen again in next 30sec, or may carry on for 30min...
Tried injector cleaner.. Sort of helped but problem is returning...
Am.i right in thinking it's an injector issue? .
