I don’t know if this is the same. I just put an aftermarket gauge on my truck because my stock gauge is sometimes showing high, as in pegged.
Running around on the flats the new gauge stays at 195°. The stock gauge had been acting ok after installing the new gauge. Drove over the mountains the other day and the new gauge got up to 205-210° (maybe higher, fuzzy memory suddenly) while climbing, and the stock gauge pegged all the way to the right.
Funny, before I climbed the second pass the new gauge showed 195° and the stock gauge came back to the L in NORMAL, where it usually runs. The new gauge showed 205-210° while climbing and the stock gauge went up a little.
Don’t know the history of my radiator, may change it. I don’t like the temp. going up while climbing through the mountains when I’m empty.
My other gauges work good as well. HTH.
