need xperts openion.
my 2006 city fans are direct and once i make it on auto car was heating up quite alot. now again it was on direct. when ever i start the car, quickly i check the water in radiator it was a glass less, and when i open the cap water flows like a shower, (one thing to mention a cool engine just started and opened the cap water flows).
one of the mechanic said your gas kit was gone thats why radiator is making gases in it and let the water flow like a shower.
i have also observed that while driving on CNG the RPM meter dance, going up to 1000 and 500 and soo on. when applied brakes RPM goes down to 0, i need to keep my foot on excelator else car will be off. AC i cannot run on CNG. it vibrates much more.
for CNG thing i have changed the new Advancer and Kabli 4 coils. at start car runs ok and leter after some times RPM issue again came.
one of the person said, due to gaskit CNG tuning make issues, first change the gaskit and CNG tuning will be ok.
Engine Check light is on just after car starts. car is perfect on petrol with and without AC, runs soo nice and fast. trouble free.
Im worried people says if once head was open then car starts making trouble always. is that true?
