Hi,

It's just about impossible to overheat while driving at highway speeds. Ram
air really cools the radiator down. The hottest the cooling system temps
will be stopped in traffic with no ram air.

You didn't mention a couple of things. What is the "touch" temperature of
all sections of the radiator and does the aux fan switch when the coolant is
being displaced into the overflow bottle?

Barring a combustion leak into the cooling system, either the water pump
impeller is not pushing the coolant toward the radiator or the thermostat is
stuck closed blocking the needed flow of cooled coolant from the radiator.
As for a combustion leak, before the system boils over, the vapors in the
coolant tank should be sampled with a device called "block-check". If
combustion gases are present in the coolant system, a test fluid will change
color.

The other night I became annoyed by yet another uninformed negative comment
about WBXs and I wrote a post that essentially said that WBXs are very
reliable. My point was that the WBX reputation has been forever eroded by
poor maintenance, lousy diagnosis and improper repairs. I received several
replies that said my comments were too harsh toward the people that use
guess-work to butcher a WBX and set the stage for later side-of-the-road
dilemmas. In spite of spending good money, do you think the DaBomb received
correct and professional service for the overheating symptom?????

Regards,   John
