Thanks Levin818, but mine looks like the below pic and does not have individual vacuum outlets. So I wouldn't know how to use the carb balancer if I had it.
Also, if I tune it idling down when a/c is on to RPM900, would it affect the idling when the a/c if off?
cuscostrutbrace: Is all 20v water temp at 82C when a/c is on? I thought it should be lower since both fans are on...
Well,the water temp sensor and water temp switch position are different.The water temp switch is at the cold side(before cold water enter the engine/before thermostat),the temp switch will switch the fan on at 93deg and switch of at 83deg,so where it is positioned doesnt matter because the thermostat will open at 82deg,water temp will rise eventually.
The water temp sensor positioned after the thermostat,where the water circulates. Means before 82deg,the water inside the block just circulates inside the engine,and this temp sensor can measure the variation in temp from cold to hot..
Let see,thermostat full open at 82,at this time the fan is off,so after a driving while temp will raise to 93,then fan kick in,temp goes down to 83,fan switch off,but since the fan is off at this point,temp will raise again after driving for a while..by theory,the water temp should not fall below 82deg,because the fan will be off at 83deg so there will be temperature build up after that as there is no cooling air for the radiator....unless the fan does not switch off at 83deg,still running until temp drop lower than 82deg.
