has anybody removed the pan under the engine and checked the temperature shown at the dash?
i ask because the engine is very hot at touch and does not have much exit for the air flowing around.
answers only from those who have done this please.

 

I've tried it. No measurable difference. I also pulled the weatherstrip that seals the back of the hood to the cowl. All I got for my efforts was a filthy engine and hood insulation. I even tried pulling the fan and shroud to see if it was a restriction at high speeds. Total failure. My testing was at the race track in 95º heat.
(It may help while sitting in traffic but not while at full throttle on a track)

great! thank you very much. it was just an idea to see what can be done. this engine seems way hotter than any other i have had before. even the fenders get hot on a normal 72f day.
thanks again.
i see that you just edited. i drive in traffic but also at the road, and i have tested it only after driving in traffic. so, after all, it may work for me...and i dont drive on dirty roads. no worry getting dirt.
lets see if any other has an experience too.

It also acts as a shield from debris hitting anything under the motor (like FOD punching the oil pan/hoses/lines).

My crossfire is missing the undertray - any one have one to sell?

My last two Roadsters have not had the pan. My SE didn't when I got it, and I took the one off the Graphite as I hated dealing with it doing oil changes.
My engine bay is clean, I keep it clean with minimal effort - and my car is up to 60,000 miles now.

I did the same thing as Less did verbatim we did this 10 or so years ago and with no good results so the cawl rubber, the belly pan and all factory things stay, your car will run cooler it is designed to run 195 to 210 degrees ,, the almost only way to run cooler is to install a 180 thermostat . Ten years ago U could find a 180 thermostat today i don't think so.
we also cut the veins in the grille . but they r designed to hold the air if u cut them air blows back forward out of the grille even at 100 mph so dont cut them.

You want to reduce heat in the engine bay? Cut some holes in your hood, that's really the only way. Alot of newer modern cars have heat extractors built into the hood.Ive seen some members had some to their hood as well.

 

Explain please, this does not make sense to me.

 

thanks. great input, as always. conclusive facts.
1 final question: how can we see this at the dash? how can we know at the needle range? for instance: horizontal means how many degrees? thanks

 

 

Mark, member Clarkcou (post 5) needs one, maybe you two can come to an agreement?

eventually found this: https://www.crossfireforum.org/forum...-position.html
still would like to learn how this matches the temps mentioned by amx. (195 to 210)

 

i MADE INVERTED HOOD SCOOPS TO AVOID STATE POLICE ISSUES, WORKS GREAT AND COOLS AS I TESTED IT WITH THERMOCOUPLES, ENJOY, WOODY

very interesting. thanks for sharing. i was on the idea that the exit should be near the rear, so air blows from the front around the engine and then exits behind. but if your way temp drops, then why not.
and of course, that the air filters are there at the back so there is no room there.
the only thing that must be taken in account is that rain/whatever does not run inside with the openings.

 

These cars seem to run very cold though, I think it's that weird gauge having the default slightly above middle that scares people into thinking these things run warm. Based on my OBDII reader, my Crossfire is the coldest running vehicle I have.

My E90 would run as high as 234F, which is normal in "Eco" mode, and my new RAM Rebel will typically cycle from 205F - 230F in normal driving, again considered normal for that vehicle. What's interesting is both their analog gauges would show at the 1/3rd level even with the coolant in the 230F range, well below the middle mark of my Crossfire which was actually running cooler actual temps.

Get a cheap bluetooth OBD2 reader, use the Torque App on your phone and see what temps you are really running. You will realize these cars don't need any extra cooling.

 

could you tell the temps on your xf? and how that shows on the gauge? thanks

 

I can see the actual temp ( F or C ) on my Ultragauge

 

Sure, later today I'll be driving the car, I'll compare the actual temps with the analog temps. I'll be sitting in a long In N Out drive thru line as well, will be able to get max temps.
