I am suffering from a very slight coolant loss from my TD5 Defender. At worst it is about half a litre every month but it doesn't seem to be regular and is low enough to just top-up and forget.
BUT - is it the start of a more serious problem or just a minor pipe leak?
I cannot see any signs of fluid loss on visible pipes and rad-weld doesn't seem to stop the problem.
No contamination in oil or any signs of other than perfect running from the engine.
Every now and again I get a slight smell of coolant inside the Landy - could this be a hint that it is in the heater honeycomb?
I have replaced the pressure cap just in case that was faulty.
Any suggestions would be apreciated.
