Question & Answer
| No. | Question & Answer |
|---|---|
| Q1 |
Q: Which machinery fits ZVEZDA 31A90-00601 oil pressure warning switch? A: Direct replacement for all equipment equipped with Mitsubishi S4S/S4Q2/S6S diesel engine, interchange OE 31A9000601 & MM409580, standard external thread screw-in install without modifying engine oil gallery. In stock, ship within 1–7 working days. |
| Q2 |
Q: Oil pressure lamp still no low pressure alarm after replacement? A: Fatigued stainless steel sensing diaphragm leads to shifted trigger pressure, replace complete ZVEZDA integrated oil pressure switch to restore accurate low oil pressure warning function. |
| Q3 |
Q: Can this oil pressure switch replace intake MAP sensor or coolant temperature sensor? A: Not interchangeable. This mechanical lubrication oil pressure alarm switch detects engine lube oil pressure; MAP sensor measures intake air pressure, water temp sensor monitors cooling liquid temperature, different working medium and detection principle. |
| Q4 |
Q: Core advantages of ZVEZDA 31A90-00601 engine oil pressure warning switch? A: High fatigue stainless steel sensing diaphragm, stable fixed low-pressure trigger threshold, thick anti-corrosion galvanized steel thread body, grey elastic oil-proof insulation sleeve, HNBR high temp anti-leakage sealing, OEM standard thread size direct bolt replacement, neutral unbranded packaging, perfectly match Mitsubishi S4/S4Q2/S6S engine lubrication pressure safety alarm system. |
