Duratec 2.5 Live Coolant Temp

Recommended Posts

Had the typical water pump failure. Replaced with a pump with a cast iron impeller and a new 180 degree thermostat. Burped the system.  Car runs great (aside from my P1744 which is another story) with the dash temperature gauge steady on the A in NORMAL.  Hooked up my Uscan Bluetooth OBDII and in live data you can see the thermostat open at 180 with temperature drop and then after driving it reaches 203 to 207 depending on traffic...with dash gauge at A

 

Would you consider this normal?  I know some cars run over 220 but this seems warm to me. Doesn't seem like any air in system and I didn't see any pieces of impeller in hoses (I took both halves of pump out)

 

Thanks in advance for your thoughts

is your heater hot? if not that is an indication of air. If the fans are coming on it should be just fine but in the evening when your done driving I'd leave the cap off of the reservoir for a couple of days just in case there was some air in it still. I think I've seen mine up to 211 degrees and no issues.

Hi...Thanks   Yes heater is hot. Fans come on. Its very hot here now....over 90....  I can't say I use the car a lot. I bought the car from a co-worker sight unseen for $300 in 2011. Didn't know what make or model it was and didn't care for that price. When she handed me the keys, manuals etc and told me where it was in parking lot I was surprised it had 56,000 original miles. Just turned 75,000 today.  I've rebuilt cars since I was young. I put a corvette 327 in a Vega before they made kits. Made all my own brackets, z-bars etc etc. Had lots of cars I wish I still had. Have rebuilt a long list of car and boat engines, yet everytime I open the hood of the Mystique (which I call the mistake) I can only shake my head...I envision the designers discussing it "Hey Bill, where should we put the alternator?"  "mmm Why don't we squeeze it down near the axles so it can be underwater when we go through a puddle and it can slide through the snow and ice" ..."Fabulous idea"

 

I posted pics of it in the garage.  I've almost given it away a dozen times. At least I have met some new friends here who would appreciate it if I reach that point again. Thanks for your help

LOL, I have a friend that put a 455 in a Vega. The stories he tells about it are just crazy.

 

Good Times

203 ~ 207 degrees not at all unusual in heavy traffic on a warm day. Do verify fan operation, as pointed out. As far as the dash guage showing a reading of "A" in normal - this reading should be taken as a relative postion, not as an indication of a specific operating temp of the cooling system. This reading varies based on the dash temp sending units. I have posted in the past how many senders, all at room temp, had ohm readings that varied greatly (hence different dash temp guage readings).

Thanks I was just wondering if my radiator was potentially clogged..even a little. Has no overheat symptoms just didn't know if those live temps were within range. I know some cars run way hotter than that
