Another overheating problem

<< < (2/5) > >>

Mark2Disco:
yes i have the same problem
even without towing
go above 70 mph for a few mins and temp goes up
slow down to 70mph and temp is fine
will tick over all day without the temp moving up
i think the rad is full of sludge
the pipes in the rad are only very small and if there is sludge in the
rad the coolant will not circulate quick enough to cool the engine
at high speeds or when under load
i did have problem with heater being poor
so i flushed it out and is now fine
there was a lot of sludge in it so im thinking it must be the
same in the bottom of the rad

i think what is happening is the veins were furrred up, not completely, but enough to reduce th ecooling, but not enough to stop the complete flow of water through it,    only my experience ,good luck hope it helps

I had this problem with my 200Tdi Disco.  Rad looked ok and flushed out fine - if a little dirty, but a new rad was the cure.

winchman:
The same happens to 405 heter matrixes, very good points keep us posted

denviks:
i have exactly the same propblem...... no idea what it is. im pulling the caravan to scotland next week but it will be fine as im only doing 60 mph. anything above that and she gets hot. the rad is spottless on the outside and i have flushed it forwards and in reverese. to be honest it was very clean inside too. im gonna fit my kenlowe when i get back off my holiday to see if that makes a difference  :D

burgerman:
defnitly not saying i know best but after blowing/melting one van to  bits on the motorway i would strongly suggest replacing the rad, i mentioned that we cleaned out the rads even put some "nasty chemicals" through them, no difference,    dont shoot me down in flames if its not the cure but i have known many instances of this and the final piece of the jigsaw--new rad       good luck
