I have a 1997 5.2 L and the truck runs at a constant 200 , is this to hot? I have never had a car or truck that ran that hot before. My coolant level is fine and has not been leaking anywhere. Any ideas? Thanks

 

My guage never gets above 180...never saw it at 200 ever!!!!!!!!! Sport 5.9

 

sounds about right for a stock 195 temp t-stat...

edit: oh yeah... 185 or so... was pretty constant over the weekend with outside temps around 95 deg and the ac on... (going up hill too)

 

My 99 5.2 runs 200 to 210 consistently.

 

Mine runs that high as well. The factory t-stat is rated at 198.

 

my truck runs at 180 consistantly

 

mine runs around 175-180.

 

I run at about 180, if you trust the stock gauge (I don't). Who knows, as stock gauges are generally notorious for being off quite a bit. Bottom line, keep your temps down; if you don't, it'll cook your tranny due to interaction between computers per my Diesel mechanic. If I rememer correctly, he said that high cooling temps make the engine computer run the motor richer, which overheats the cats, which heats up the tranny, or in some other way affects the transmission. I definitely trust his expertise as he is a diesel guru. Don't know if similar high temps would affect a gas vehicle, but I wouldn't think it would be much different.

 

I run just below 200. Used to show 210 before changing out thermostat to 180. Like mentioned,how accurate can the factory gauge be?
