The 195 was just the factory choice because it is the best temp for emissions. The 180 is actually better for performance and helps stop/reduce any knocking/pinging, especially with the mopar performance computer... which is why I have a 180 deg in my truck. So for me, I "should" be running a 180 deg. Maybe a 195 would be better for the OP, but you can't just say he "should" be running a 195 without knowing anything about his truck.

Thats the first sign the pump is starting to go out. I replaced mine a little over a year ago and the pressure sits steady whether the engine is idling, WOT, etc.

 

great it just started doin that. i wonder how long i got till it goes im unemployed right now i cant afford to have it go out any tips to baby her a bit longer? it hard to replace?? expensive part?

 

From NAPA's website:
$32 for V6/V8 pump.
$76 for V6/V8 high-volume pump
$62 for I4 pump.

So, not that expensive.
For 4x4 vehicles, the front axle has to be moved (or the engine lifted out of place)
That's all I know.

 

My Jeep will idle 30psi when idling when its at operating temp and rise between 50 to 60 psi when driving. And that has a new engine in it. I wouldn't worry about. It just means that your guage is working properly.

 

You need gas too...lol

 

No, you don't need to worry about it right now if thats as low as it goes. As long as its in that normal range you're fine. Just keep an eye on it and if it ever goes below that first "normal range" line, then you need to replace it.

I was just simply stating that losing pressure at idle is the first sign of a pump going out to bring it to your attention.

 

I have the same problem with my heat. My guage reads like that and my heat isn't hot. And now i have a mild smell of coolant when i turn the heat on.

 

MustangMabry, sounds like a typical case of having a cracked heater core. If you are smelling coolant, you can probably rule out backflushing the core and go ahead and just replace it.

 

Dang, thats what i was afraid of!!!

 

my temp sits at around 190ish, but takes forever to warm up
