Cooler running

[latham91]

Hi all,

Noticed the engine temperature getting up a bit the other day through town and then when I got home I let it idle to see if the fans would cut in/out and control the temperture. They did cut in/out and there was some control but the temperture on the dash board gauge was eventually showing 105C and also 103C on Rovergauge at which point I switched off to let things cool down. I do have a manual fan over ride button under the dash but it would be nice for the engine to regulate itself a bit better. I was wondering whether to change the thermostat (where the top hose goes in to the top of the inlet manifold at the front of the engine?) and also the otter switch (mine is on the n/s of the radiator) to both let more flow through the radiator and also switch the fans on earlier. Has anyone got any recommendations for this?

I think the radiator and general cooling works OK since when I use the over ride switch to put the fans on constantly they bring the temperture down nicely.
Mines a bog standard 400 on a T-plate by the way...

Thanks, Ed

It was last Saturday - not especially hot ambient, say 25 degrees? I didn't take it out on Tuesday when it was over 30....

Hi, yes, flushed it out last year and it does cool down once one the move or when the fans come on. Think i,m tempted to put a 74 degree thermostat in and see what effect it has.
Looks like tvr parts do one at a reasonable price.
