Yes this was the original rad, maybe the pressure / rate at which the new pump was working at has made the old rad go pop,  as i work six days a week a friend is fitting the new rad at his workshop, to be honest im running out of things that it can be so fingers crossed.

Does anyone have a picture to show the heater matrix pipes in the engine compartment so I can have a bash at flushing it?  SOS to hijack thread..mines freezing...

Not sure what Jeep you have , but if its any clue , on my Cherokee diesal there are two metal pipes going across the top of the cylinder head....These head over to the passenger side and dissapear into the bulhead...

These are the heater pipes... They should both feel hot when the engine warms up...if one of em is cold...you have a blocked heater core...

Thanks wild rover .. I thought it was them.. They're both hot... Still no heat from heaters though...   Thank you

If they're both hot and you're not,the matrix be bunged up.

there should inly be two black hoses throught the bulkhead, located just to the right of the engien (mk1). pop these off and use a hose pipe to push some water through. build the pressure slowly as too much can damage the core. blow through bothe directions.

Back to the original thread, new rad is on and so far the temp guage sits under half driving around town, gonna take it down the m1 for a proper test tomorrow.

Stay cool.

I'd bet ya fixed it now.

[Grays85]

Hope m1 trip went well...?

[just-boot-it!]

Seems sorted now, the fan dosen't kick in at all as the temp guage stays one notch below half, as you can see from the old rad she was abit tired. Went down the m1 and it was fine upto 70, thats fun on MT's!  I was so happy I went for a small trip out!  Thanks for all the advice peeps.
