I'm in eastern Ontario and have noticed this behavior during the last
week or so during our heatwave (as well as the previous one earlier this
When I start the car after it has sat outside for 8+ hours at the bus
station in 30+ degrees Celcius weather, the radiator fans do not come on
when the temperature guage is at 40 (cold) or even halfway.
However, if I turn on the air conditioner when the temperature guage is
at 40 (cold) or even halfway and the outside ait temperature is really
warm, the the radiator fans come on.
This did not happen last summer in similar heat conditions, so I am
wondering if something got buggered up with the cooling system when the
lower intake manifold gasket was repalced a few months ago.
This only seems to happen when it is really hot outside.
Any ideas what might be causing this?
