Temperature gauge fluctuating

[chamberlain]

Just got back from a short trip towing my toad and noticed during the trip my guage was moving a lot from1/4 high to 2/3 high but never got above 50%. It didn't happen much at all going at a fixed speed but did change some under different loads. Is this normal... as before I remember the guage just plain staying on the same reading unless I was climbing a steap grade. So far the rig has never run hot at all

Thx John

I would check coolant level first, and then make sure that the fins on the radiator are clean and free of any obstructions. Verify that the engine fan is working properly. Just go down the list doing the easiest and least expensive first.
