Thanks for the offer. I bought this car from the Boston area 13 months ago. 126,000 miles. The problem is that once on the highway, it will heat up to the point of a warning light coming on asking me to pull over to a safe spot to idle. The temp gauge will then go back to mid range. Back on highway, starts to spike again. Had a new thermostat installed 12 months ago, the whole system flushed, new hoses, new coolant etc. yet it still behaves badly. Recently tried an engine coolant, take out 16 ounces of coolant and put in this product to cool engine. Didn't work. The strange thing is that it doesn't overheat in town, only on the highway after 20 minutes of driving. I can manage at 45-50 mph and flashers on, but that's not supposed to be how it works. Please help!!!!!!
