Having bought my 06 GX 470 only a few months ago, we're encountering 90-degree-plus days for the first time. There is an unusually loud noise from the engine that I'm almost sure is cooling fan noise. It occurs after running in the heat of the day. It's not mechanical noise, but a loud roar like that of a large truck engine.
Is this typical for these models in the heat?
Does anyone know of a fix for this? a quieter fan, etc?
Thanx,
Bill
