Hello guys, I have been reading up on heating problems , but I am still puzzeld ( this happens a lot. the car is still overheating after changing the thermostat with a Robert shaw 180 correct orifice plate and a new waterpump flowcooler after the weiand failed. There is no bypass not on the weiand and not on the flowcooler ( witch is there only for warm up , right.... or not? I have the Original radiator witch I want to keep, coolant is changed and clear two sucker fans on the front of the radiator?? operating manually. The car runs fine, but the only time it was not overheating was when I drove it back from Sweden. Now I have been thinking the guy gave my some bothels of octane inhancer so I think he used them reguraley. Would this ad to cooling? I am using 98 octane gas at the moment, Would this be the cure for the problem or do I have to drill the bypass hole or do something else. Temp goes to more than 100 degrees at that point I stop the car. I am using coolant ready made. Any advice welcome, thanks Urbain.
