Improving Forged Engine Longevity w. Coolant Pre-heaters (i.e. Webasto, Eberspächer)

[wpod]

Forged pistons do shrink (cold) and swell (hot) but if you got that many years (17) it doesn’t matter to that configuration.
Concentrate on the specific oil required and drive easily until full operating temp. Then let her rip…

All pistons expand with heat and return to size at low temps.
