Hello


The family drove our 2003 Disco 2 from Los Angeles to Las Vegas over this Memorial Day weekend. I have an Ultra-Gauge attached to the vehicle.


On the way from LA to Vegas which lasted from 8 am to 1 pm I observed my coolant temperature was fluctuating in a range from a low of 188 degrees F to a high of 216 F. Ambient temperature was between 100 to 102F.


On the way from Vegas to LA, we headed back at 2 pm and observed my coolant temperature in a range of 188 F to highs of 221 F. The temp alarms went off multiple times when temps hit over 220F specially when climbing uphill. I looked at the factory analog gauge and it was still pointing in the middle. Ambient temperature was between 102 to 107F.


Fortunately whenever the temp alarm over 220F sounded we were reaching the top of some hill so I let it go past the top and coasted downhill which caused the temp to go down several degrees. This happened about 4 times during the trip. Very nerve-wracking!



We made the trip back without any drama and the disco appears to be ok.

I checked the Rave manual and couldn't find the normal operating temperature range (or missed it). Are these readings normal or is it something I should be concerned with?


Sincerely
