Austin Healey 53-56 Triumph Smiths Heater core

HC 53-56 Austin Healey Smiths donut

$1,156.00 $1,150.00

When we saw this Austin Healey Smith's FWM3321 heater core replacement with massive tubes and spirals being sold for $1200 we thought, "That's crazy! We can make a better here for less." Huge tubes mean most of the coolant touches coolant and too little touches tube wall where the heat exchange happens.

Dimensions 7-3/4" OD - 4-3/8" ID - 4" tall
1/2" tubes stand 6" above the heater encasement
