I think it's telling you the rad is choked. With a good flow of water, and no airflow (so it's only, err radiating) there should be little temperature difference along the width, and not much top to bottom either. You've eliminated the thermostat. Poor flow then - unless you have something unusual for a V8 in way of broken/corroded water pump vanes - is most likely choked rad. It might improve with some caustic treatment, might not, may just spring a leak! Recored rad is the surefire fix.
cheers, Ross K
Range Rover Blues:
If it's like the RRC then it will be a full width full flow (cross flow) rad, once up to temp you shouldn't be seeinng so much variation side to side so I think it's blocked.
Also, I know you have no 'stat any more but those readings are a little low, the 14CUX will run rich until you clear 80 degrees.
SteveGoodz:
Cheers to Rossko and RRB - you confirmed what my feeble brain had been trying to tell me all along :lol:
Replacement (used by guaranteed) rad turned up whilst I was out today ... so that's this weekends job decided :clap:
SteveGoodz:
Okay, so now I'm seriously miffed :evil:
Took the original radiator out of the Discovery this morning and slotted in the replacement one ... it leaks like a sieve :-. We are not amused!
No alternative but to flush the old one and refit it. At least it doesn't leak. I'll be on the blower to Amazon 4x4 first thing in the morning to get my money back
SteveGoodz:
And finally ....
... refund from Amazon 4x4 for the "less-than-watertight" radiator is on it's way :)
... a huge thanks to "Staffy" for letting me have a reconditioned rad for much less than he could have got elsewhere. Cheers Phil, you're a true mud-clubber :clap: The beers are on me next time our paths cross :dance:
... overheating now appears to be a thing of the past - touch wood [-X [-o<
Driving up to Stoke was a bit of a nighmare yesterday. Hottest day for some time so I was balancing speed on the motorway against engine temperature. Just around J3 of the M5 the temperature gauge suddenly shot up into the red. BU66ER!! Turned out to be a split heater hose which was fixed by the nice recovery man. From there, all the way to Phil's place and back was a very warm experience ... driving with all the windows and both sun-roofs open and the heater on full blast [-X
Well worth it though :lol:
