CLASSIC THUNDERBIRDS - 1955-1957
-Use Premium Fuel
-Radial tire pressure should be 35 psi
-The original temperature and Fuel gauges are not always accurate. Installation of aftermarket gauges is recommended if you desire more accurate readings.
- Use 160 degree thermostat and six blade fan for better cooling
-Remove exhaust control valve (heat riser). These stick with age and corrosion, are a major source of overheating and often cause exhaust manifolds to crack.
-Expect some small oil leaks
-The more the vehicle is driven the better it performs
-Modern 10W30 oils no longer have enough zinc additive for the flat tappet camshafts these cars came with. Use engine oil with zinc additive like Shell Rotella T or AMZOIL ZRod synthetic, otherwise a zinc additive must be used with your regular 10W30 brands like ZDDP brand additive.
