Tuning … & Water System...

[VoipX1]

Hi,

How can I get my engine tuned ? seems to be doing at most 29 miles per gallon averaging about 24 miles per gallon….

also seems to be running quite hot although the water indicator is fine...

also is the water meant to be pressurised ? the pipe from the water overflow tank seems to be blocked….

Thanks...

Hi

I would have thought 29 mpg with a average of 24 mpg this time of the year would be about right for a GS300. mine used to do around 24 – 25 mpg in the winter and 30 mpg ish during the summer although I only do short trips

Your cooling system should be pressurised when the car is hot, make sure your overflow tank is up to the max level. is the heater working ok, is it blowing out hot air, if not it may be a faulty thermostat.

yes lots of hot air coming out...

is the exhaust meant to be so hot ?

mine is really very hot...

but nothing else seems wrong...

I am NOT a mechanic although I used to tinker with cars years ago before they came unbelievably complicated, I would have thought if your oil, and water levels are ok and the temperature gauge is showing normal running temperature then you haven’t got a problem, the exhaust gets hot but if yours is getting overly hot its difficult to say so perhaps a visit to a qualified mechanic may be a good I dear just in case and for piece of mind.

the engine does misfire at initial inanition until the engine warms up… then it run s smoothly...
