https://durafit.my/tech-notes/ Straight answers about filters and wiper blades for the cars Malaysia drives. en-my Mon, 19 Oct 2026 00:00:00 GMT https://durafit.my/tech-notes/proton-saga-filters-wiper-size/ https://durafit.my/tech-notes/proton-saga-filters-wiper-size/ Mon, 19 Oct 2026 00:00:00 GMT For the Proton Saga, the DuraFit air filter is SAQM03AF10704 (Proton OE number PW810704, 322 × 140 × 38 mm) for the Saga BLM, and the cabin filter is SAQM04CF05448 (OE PW954147, 193 × 178 × 18 mm) for the Saga BLM and MC2. Wiper blades are 22 inches on the driver side and 17 inches on the passenger side for Sagas from 2008 on, with a U-hook (adapter A) fitting. https://durafit.my/tech-notes/aircond-smells-after-rain/ https://durafit.my/tech-notes/aircond-smells-after-rain/ Mon, 19 Oct 2026 00:00:00 GMT A musty smell after rain usually comes from moisture and dust inside the aircond: a damp cabin filter, and mould on the cold, wet evaporator behind it. Replace the cabin filter if it is dirty or damp, switch the aircond compressor off and run the fan for the last few minutes of a drive to dry the system, and check for wet carpets. If the smell keeps coming back, have a workshop clean the evaporator. https://durafit.my/tech-notes/air-filter-fuel-economy/ https://durafit.my/tech-notes/air-filter-fuel-economy/ Mon, 19 Oct 2026 00:00:00 GMT On modern fuel-injected cars, a clogged engine air filter has little effect on fuel consumption, because the engine computer adjusts the fuel to match the air. What you lose is power: in tests by Oak Ridge National Laboratory for the US Department of Energy, cars accelerated 6 to 11 percent faster on a clean filter. Replace the filter at the interval in your service book, sooner on dusty roads. https://durafit.my/tech-notes/haze-cabin-filter-malaysia/ https://durafit.my/tech-notes/haze-cabin-filter-malaysia/ Mon, 19 Oct 2026 00:00:00 GMT Check the cabin filter after a haze episode and replace it if it looks grey or clogged, or if the aircond smells musty or blows weakly. While the haze lasts, drive with the windows up and the aircond on recirculation, so the air keeps passing through the filter instead of coming straight in from outside. https://durafit.my/tech-notes/proton-x50-oil-filter/ https://durafit.my/tech-notes/proton-x50-oil-filter/ Mon, 19 Oct 2026 00:00:00 GMT The DuraFit oil filter for the Proton X50 is SAQM02LF00383. It replaces OE number 1056022300, measures 92 mm high with a 69 mm outer diameter, and is also listed for the X70 (CKD), X90 and S70. Change it with every engine oil change, at the interval in your service book. https://durafit.my/tech-notes/cabin-filter-signs/ https://durafit.my/tech-notes/cabin-filter-signs/ Mon, 19 Oct 2026 00:00:00 GMT Replace the cabin filter if the aircond blows weaker than it used to at the same fan speed, smells musty or sour when you switch it on, takes longer to clear a fogged windscreen, sounds louder for the same airflow, or the filter looks grey and full of debris. Otherwise follow the interval in your service book. https://durafit.my/tech-notes/oil-filter-interval-malaysia/ https://durafit.my/tech-notes/oil-filter-interval-malaysia/ Mon, 19 Oct 2026 00:00:00 GMT Change the oil filter every time you change the engine oil. Use the interval in your car's service book, and if it lists a separate schedule for severe conditions, that is usually the one that fits Malaysian city driving: short trips, stop-go traffic and high temperatures all count as severe. https://durafit.my/tech-notes/wiper-judder-rain/ https://durafit.my/tech-notes/wiper-judder-rain/ Mon, 19 Oct 2026 00:00:00 GMT Wipers judder when the blade edge sticks to the glass instead of gliding. The three usual causes are a dirty or waxy windscreen, rubber that has hardened in the heat, and a wiper arm that no longer holds the blade at the right angle. Clean the glass and the blade edge first; if the judder stays, replace the blades, and if new blades still judder, have the arm checked. https://durafit.my/tech-notes/inter-monsoon-wiper-blades/ https://durafit.my/tech-notes/inter-monsoon-wiper-blades/ Mon, 19 Oct 2026 00:00:00 GMT Replace your wiper blades if they leave streaks or a smeared film, judder or squeak across the glass, skip patches, or the rubber edge is cracked or torn. With afternoon storms expected until the end of October and the northeast monsoon usually starting in November, now is the time to check both blades and fit the right length for your car.
