Sorry if I'm asking the obvious, but if it only happens when stationary, are you sure the electric fan is fully efficient?

YES Optimax, This will richen the mixture slightly and help it run cooler. Is the air filter clean?YES Are you sure it is allowing the engine to breathe sufficiently? Try a K & N type? Fitted Are you sure there are no air leaks allowing the engine to lean off? Will Check 2 Is the alloy radiator larger than the original , or the same size? My Mulfab one is deeper by several cms. Techniques Larger 3 Are you sure you don't have any air locks in the cooling sytem? Reasonably sure, on the road engine nicely stable at 95-97 C 4 Have you changed the expansion tank cap recently, they can age and allow the water to boil at a lower temperature.No but see previous 5 Have you backflushed the system recently , crud in the bottom of the rad can affect water flows a lot. Backflushed no, Rad fitted 18months annual change of coolant with pre rinse through 6 Is the number plate or anything else impeding the air flow into the radiator core? No I am paranoid about anything in front of the grill, no badge bar even 7 Are you positive that you don't have any head gasket issues? Checked 8 years ago, no issue on the road, just in traffic, but perhaps will check. However oil always clear as new when changed. No sign of oil in coolant. Thanks Andy Problem only occurs when stationary in traffic or slow moving. The radiator is clear and the Spal fan works OK. As above engine runs at a steady 95-97 when on the move except on very hot days e.g. LeMans 2010 air temp 104F+ Regards Dave ------------------------------------------- View posts on The Mail Archive http://www.mail-archive.com/[email protected]/ [http://www.mail-archive.com/[email protected]/] Modify Your Subscription: https://www.listbox.com/member/?member_id=22459785&id_secret=22459785-4a39ddf8 Powered by Listbox: http://www.listbox.com
