When restoring or maintaining a classic Holden, accurate gauge readings are essential to keeping your engine protected. The Temperature Sender Unit is specifically suited to Holden EH, HD, HR, HK, HT, HG, HQ, HJ and LH, LX, UC Torana models. Calibrated strictly for vehicles equipped with a factory temperature warning light system — commonly referred to as an “idiot light” — this unit functions as an on/off thermal switch rather than a variable sender for gauge displays, ensuring dependable and period-correct operation for classic Holden applications.
