trust me very hard to find the factor...mine d16 engine is water sucking...always have to refill every 3 days...lost about 500-700ml per 3 days but not yet overheat..the indicator still in normail level point...my last resort is waterpump...so just keep refilling the radiotor untill next beltings change...overheat cause by many factors..but better cheek external parts first..from radiator,hoses(presure test), radiator fan or thermostat...if involve interior engine parts, worth way is convert ur engine..:hmmmm::hmmmm::hmmmm:


alrite guys probem has been solved.... problem is the fan spin on the wrng directions hehehe
yup the fan i install blow the heat out thru the radiator. no wonder if driving makes the car overheat. if car stays it wont over heat
