One local rad shop recently told me that reverse flushing is one of the main causes of thermostat failure, though it normally does the opposite - makes the engine run too cool as the center gets displaced and allows too much flow. <BR>I agree totally with DougM - or vice versa - overheating problems are always caused by some problem in the system, and changing a perfectly good thermostat for one of a different temp will not fix the problem, nor will wetting agents.<BR>Gord, - most Japanese vehicles are modified for the country of sale - except of course, private imports.<BR>Darryl<p>[ 16 December 2001: Message edited by: DarrylH ]
