Hi All,

This is an informative post about my journey with my running temperature on my 400 in my first year of ownership.

The car has always run at 92 never any lower, this has been confirmed by temperature gun and rovergauge. Which in itself is not much of a problem, but doesn't give me much room when I hit traffic on a hot day and the gauge creeps up to 100. Never overheated though.

After replacing water pump, rad, thermostat, coolant flush, and fans...... all of which were under par. I now ran at 82 degrees, but if I ever hit traffic the car went up to 92 and then onto 100 and never came back down below 92 on the move...... strange.

The answer.......... the grill. Whilst looking about I found a second hand chimaera grill, which looked the same but had many more holes in it. My grill being black it never stood out before how few holes it had. Replaced with a mesh and a years worth of stress has been lifted. Steady at 82 biggrin

I think this is a rare problem, but for unsuspecting newbies that don't know any different just check the grill before you go mad.

Yep, having had my fingers literally burnt with my Range Rover 3.9EFi when I got caught in M5 traffic on the hottest day of the year. After a new head gasket I made a vow to make sure all my V8s cooling system's are up to standard smile
