Thanks Antny. Any idea how I can check whether the engine compartment fan is working correctly? When the car is at temp, I can hear the front fans on high - sounds like a Hoover under the front of my car - but I can't distinctly hear a fan in the engine compartment; or rather, I can't tell if the sound I hear is coming from the engine compartment or from the front fans.
Also, how concerned should I be that the temp spikes when idling? When I parked the car at work this morning, I got out to listen to the fans while the car was running, and in the couple of minutes I spent doing that, the temp gauge spiked from its 'new normal' to about midway between the fourth hash mark and the 250 mark.
I plan to clean the radiators this weekend. I'm not normally a DIYer when it comes to vehicles, but that seems doable.
