More heat

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.

There was some mention of these pipes a couple of months back on here IIRC. For what reason I don't recall.

We had almost identical problems a while ago. RCV near us reckoned it was a bust head gasket and we let them do the work as I didn't have time or space to do it ... but the symptoms persisted. In the end we had to replace the radiator. When the old one was off it was apparent that about 3/4 of the rear of it was 'eaten away' by whatever bugs/trees/stones/ had come through the front and exploded out the back! A replacement radiator cured it completely, and they sorted out the costs so we didn't lose out and got a head skim etc virtually free of cost. ;)

I'd remove what you can and try to get a good look at the whole of the back of the radiator before doing much else.

My 90's one was full of driffield clay....

it never ran more than just under half though all the way back home.

I was amazed at how much clay came out of it after a spell wit the hose pipe

Must admit the radiator gets a lot more attention from me now. After Tong, where it had been under water a couple of times, it was covered with that watery slurry type of mud that just coats everything with a thin layer. I'd guess there was a couple of pounds, minimum, of mud just in the rad ... ;)

Thanks for the heads up chaps - the rad will get a decent dowsing on the morrow, possibly followed by a blast from the new (to me) Karcher.

Just been to Manchester & back - round trip of 450 miles or thereabouts.

No temp issue at all - can't check the fluid levels tonight but I will in the morning.

Do *not* use the Karcher on it - it'll blast all the fins off it make replacement a necessity.

I normally use just a hose pipe to clean it, but to be honest i had to use my pressure washer on it after driffeld.

If you do decide to do it, make sure its well away from the rad, ie a foot or so minimum.

I bent some of the fins on my old range rover with a pressure washer once - its easily done!
