welcome to the club digger listen m8 just for future refrence capitels are considerd shouting just to let you know ,any way m8 ive got a good idea that the rad is blocked try back flushing it and see if any krap comes out ?but i do recommend you dont use the car untill you have fixed it.
if this dont help let me know and we will go through some other things.

mine ran hot amd chucked the water out the breather on the header tank , a thermostat change did the trick for that.

and welcome to the club

jon to the rescue again

My 2.8 td (1989) has suddenly started overheating. The temp gauge used to barely move even after a long drive now goes right up to nearly red quite quickly.

My plan unless someone offers a better sequence is:

First check coolant and oil level then:

1 - Remove top and bottom hose from rad and flush through with a hose (possibly put some cleaner in there as others have suggested)

2 - Blast rad externally with a hose

3 - Take the rad cap off and idle engine, look for signs of bubbling e.g from a head gasket leak (if there is - change head gasket, is this straightforward ?)

4 - With engine idling look for signs that the water pump is operating once temp goes up e.g rad cap off look for water movement (does the water pump start when the thermostat tells it to ? the fan runs continuously...) (if not working change thermostat then water pump ??) (anyone have a soft copy of any of these procedures - location of thermostat etc would be handy!! - got a cd rom of the mfctrs maintenance manual but can't seem to get it to work)

5 - Somehow check that oil pump is working - not sure how...

I've decided not to drive it until I've resolved this because it is too much fun off road to break it even if it only cost 500 quid !!

Help!!

I did all that on my mk1, had to recore the rad in the end.

digger have you fixed it ?manic mechanic you sould of opened your own new topic to save confusion but never mind m8 you call your self manic mechanic do you know much about spannering or not if you do then yes the head gasket is straght forward and by the sound of it you are in the right direction do what you said and if now better then get back to use and we will have a good head scrach and sort your problem.
quiet one have you got any pics of the tyres ,what size and how much?

[ManicMechanic]

Have you got any GA or schematic drawings then Matski ? Or did you get everything done by someone else ?

[ManicMechanic]

Yeah your right Brian - sorry for the confusion folks

Don't suppose you have any soft copy diagrams the engine/Ancillaries Brian? Got a cd from eebuygum but can't seem to run it.....

[brains]

look on the 2.8 engine manual in the engine forum , there is some stuff on the heating system.
