when my a/c is on my temp gauge goes all the way to H. i have an appt tomorrow at acura to see what the hell is going on. has this happen to anyone here?

 

Check your coolant level and coolant lines. There might be a leak.

 

i'll say

 

dbox,
Check your coolant levels when the car cools off.

If it is full , my guess is that its either a faulty temp. sensor for the electric fan or the thermostat is stuck in the closed
position causing little to no flow to the rad. Having the A/C on
puts a larger load on the engine = more heat. Best thing to do if the engine begins to get hot is to run the "heater" at 90 degrees on high fan. This helps pull heat off the engine and I will at least get ya to the dealer!

 

no...i have never has this problem..but i had this problem with my jeep..turn out too low of coolant...added some ..and now it is ok
