Change the thermostat. If the temp gauge does not move into the middle of the range, it is the most probable cause of coldness.
Is your fan electric? If not then the answer is no. If it is and you haven't got it confused with the air con then it is a owner fitted unit. Follow the wiring back to find the thermostat. If you have air con and it is these that are running then check they switch is set to off (second position drom the right) and if it is then the fun begins trying to find the fault.james said:Aha, that might fit in with another piece of the puzzle.
Do RRs control their radiator fan by the same thermostat? The reason I ask, is even when cold, on cold days the radiator fan will always run...
Thanks!
Thanks for the responses.Eric D said:You'll want a stock temp thermostat (88ºc-90ºc, 190ºf-195ºf) so your EFI doesn't go into closed loop.
Too cold and your dumping fuel out your tail pipe.
Hmm, it's the main big fan in the engine, I thought this was the radiator fan. I'll double check this weekend when I'm replacing the thermostat. I'm pretty certain it runs constantly, so I'll trace back the wires as you suggest and see what's going on.TehPriest said:Is your fan electric? If not then the answer is no.

James, my Bentley manual states 88ºc/190ºf is the proper temp thermostat for a V8.james said:Thanks for the responses.Eric D said:You'll want a stock temp thermostat (88ºc-90ºc, 190ºf-195ºf) so your EFI doesn't go into closed loop.

The Haynes manual defined the 'opening' temp of the thermostat as 173-182ºf, so I was going to aim for the 180ºf version. Do you think the 195ºf version would be more economical on fuel usage?
Thanks,

Sorry, I did read that, but I got so focused on the temp rating that I forgot.Eric D said:James, I posted in my 1st reply that you should drill a 1/8" or 3mm hole.
