How about that from Van Caf�? Something that automatically kicks the radiator fan onto low speed when you're doing slow speeds.

Subject: Re: Low Temp Radiator Thermo Switch "Better"?

I'm a firm believer in replacing radiators and using the correct 87 degree thermostat.

But I admit I've been contemplating a low-temp or manual override fan switch.  My thought process is that yes, the van's cooling capacity is plenty larger for its engine.  But on the other hand, maybe having the fan come on more could be good in situations where you are stuck in traffic a lot, and the coolant isn't doing much circulating.  I figure the temperature at which the radiator fan comes on might be based on assumptions of coolant flow levels below that which is happening at idle.

But I don't really know that this is better.  It's not like I have overheating problems or anything.  I guess I would need to get a precise sense of my coolant temperature under these running conditions to decide whether or not this is warranted.
