Engine running hot and you're guessing. That's how a $3,000 head gasket job starts. This Jaycar gauge gives you a real number on the dash — 40 to 120°C, red backlight so you can read it at 6am in the yard. Black face, black bezel, 52mm cutout, IP67 on the front face. Drop-in 12V or 24V (resistor included for 24V). Pre-terminated plug, so no splicing. Panel thickness from 0.8mm to 25mm handled with the reverse-mount lock nut. You need 55mm clearance behind the panel — check before you drill. Pairs with the MGG510 sender. Add to cart and it's on its way from AU stock
