td5 overheating

[extreme90]

right, posting to help a friend out so here goes

his td5 auto keeps overheating
now its been back to the place he brought it from and they fitted a new rad but it cooked again tonight

going along normal driving not up a hill and the guage goes into the red
if he flicks the heater onto full it brings the temp back down
the ecu also cuts in and restrics the throttle

what do you guys reckon ?

it isnt air locked as ive made sure it isnt tonight

viscous fan ?
faulty sender  :?  which i cant see as it needed refilling with water

any thoughts much welcomed

Mine did the exact same thing in Norway - temp gauge goes up to the roof within a couple of seconds.  Spoke to the garage and it's highly likely to be the head gasket.  No signs of either oil in the water or vice versa, but it looks like water's getting into the combustion chambers.  Does he ever get lots of grey smoke on startup?

i couldnt say but i can ask
i did pass the headgasket by him  :roll:
but there aint no water in oil or vice versa just like you mentioned  :?
he's got it booked back into where he had it from, but they are con artists

Apparently TD5 head gaskets go very gradually without giving much sign of what's going on.  Unlike almost every other engine which leave you stranded at the side of the road.  My garage (James French Land Rover in Standlake, Oxon, an excellent independent) suspected it was going about 4 months ago but couldn't be totally sure without removing the head.  Now they're 99% sure.  My main symptoms have been the overheating, smoking / misfiring on startup during cold weather, and occasional gobs of black smoke.

Sounds just like the head gasket - mine did exactly the same, overheated at the gentlest of hills, or when giving it some boot.......flushed everything, changed the 'stat - eventually had the head gasket done and it had gone between one cylinder and a water-way, so the combustion gases were pressurising the cooling system more, and pushing the coolant out of the expansion tank.
