Greetings
Vehicle: '95 Discovery V8
Today's adventure was a family trek to visit the blood relatives across the other side of London - not a trip to be undertaken lightly or without adequate preparation.
Suddenly, whilst navigating that rather tricky terrain between Brixton & Peckham (aka Camberwell), the temp guage shot up to just below max. Whacking the heater controls to full-tilt seemed to relieve the pressure as we gently cruised the mile or so to a suitable place to take a look-see. Temp would fall whilst stationary and rise again under load - perhaps indicating insufficient coolant?
Investigation reveals fan spinning nicely and no sign of water escape.
Finished last leg of journey keeping a beady eye on the guage and driving to the temp rather than any other input.
Time passes ... engine cools.
Fluid check. definately low, but not empty. Topped up.
Closer investigation indicates some fluid could have been escaping where a pipe from the radiator joins a unit between the air intake and the rocker cover - possibly coolant.
Fired up the motor - let it reach operating temp. No apparent leak.
Gunned it (with the assistance of a colleague - as they say in all the best manuals) - still no sign of a leak.
Return journey passed without incident.
Clues/comment/rambling-anecdote ... all welcome.
