And today I even went out of my way to let the car run with the filler bottle cap off and long story short the car runs considered normal temps when the cap is off (just above quarter) and every so often spikes up and does the usual thermo fans kick in cools it down then back to normal thermo fans shut off . But when the filler cap is then placed back on the filler bottle temps spike after maybe 2-3 mins thermo fans kick in and its an endless battle to run car colder and the thermo fans never turn off as its running "hot" never gets to half way but its not normal for this car . I have no clue as to why and how its doing it any advice/help greatly appreciated. Edited 05/05/18 07:31 AM by BFTURBO_MKII Link to comment Share on other sites More sharing options...

My car runs at about 1/3rd on the gauge mostly and gets near half on a summer day with the aircon running. Just put the cap on and drive it. If it gets over half then get worried but until then I wouldn't consider it an issue. Link to comment Share on other sites More sharing options...

As I stated it runs fine with no filler cap on car its when it goes on gets out of hand with thermo fans temp gauges from factory I never trust anyway .
