Coll Weater Operating Temps??

[55 Fargo]

Hi all, noticed my engine runs about 155 to 165 in the cool weather, with the ambient temp around 15 to 20 degrees.

Last summer I did go through some bouts of temps going up to about 195, on few occasions, with the ambient temp around 90 and humid.

I am wondering, will my flattie warm up to same temps at 20 degrees outside as it would when it is 55 to 70 outside.

I would think the cool air when it is 20 outside would flow through the rad and the heat transfer would be a lot better than when it is 75 outside.

I also now have a real gas tank, the jerry can I used to use as a porta tank, sat in the compartment just in front of the rad, no doubt it may have been blocking airflow to the rad...............Thanx Fred

Fred,

Sitting still or in very slow traffic during the summer will cause the operating temperature to go up to 190 and sometimes higher. Then in winter the car will run much cooler due to the outside temperature. Does the same thing in your modern car. Even if you don't have gage in your modern car/truck you can check that easily without raising the hood. Just pay attention to how many times your fan comes on during the summer as compared to the same driving conditions during the winter. In the winter the fan will come on much, much less because the car isn't running as hot.

Thanx Norm, this is an obsession of mine the operating temp of my engine and cooling system...............Fred
