Is it nomal to run this hot?
 

My 94gt runs on the high side of nomal when i am in traffic around town.The fan comes on every time but it is not until the guage hits around the "A" in normal.On the highway it runs alot cooler around the "O".I need a guage with degrees for starters and i'm gonna change the water pump for peace of mind but is there any other reason for such a variation in temp.I have a 5.0L in my F-250 but it always runs cooler.Any ideas would be appreciated.

To confirm the actual temp you need to either have someone with a scan tool plug in and read it or install a decent gauge............factory one is so far off you never really know for sure.
I'd bet if you drop by any of the shops that do tuning they'd be able to plug in and confirm in an instant.

The fans wont come on till 208 degrees... She'll hit the high speed setting at 228.

If you're concerned, plug a datalogger in to confirm.
I'll never use the factory gauge as an accurate indication of temp... I've found some factory gauges are WAY off. Keep in mind that the sender for the guage is not the same as the sensor for the ECU.
You could use an infrared heat gun as well....

So whats to hot to run with an alum headed 5.0? my car usually runs around 180-185. lately its been up around 190-195. I thought i had a 180 t-stat in it. But maybe its a 192. Is 195 too hot for alum heads?

No it's fine at those temps.

Thanks for the advice.I'll try a new guage and put a datalogger on it

Good to know. had me worried at first. So whats the worry point? Whats too hot?

Constant temps in the 220-225+ range, the odd spike that high is nothing to worry about.

try...
 

you could try some Red Line Water Wetter... might get it down a few degrees.. :tup

a few options.....water wetter as someone has mentioned. I use it all the time. Check your hoses..rad cap, flush the rad. Have you got cats? I just had to intall aftermarket hi-fl cats for emissions and my temp went up due to back pressure. Installing aluminum rad a s we speak. Underdrive pullies slow everything don at idle and in traffic.....yikes.!
Check for obstructions in front of the rad....

I know obvious stuff but thought I'd throw in my 2 cents
