(Answered) ICE Engines: Avoid Heat Induced Fuel Explosion Rolls

[Bison AIs]

Short: Does an ICE-powered mech make an avoid-fuel-explosion roll at 19 heat?

Details:
TW (2010 pdf) p.160, second column, "ICE–POWERED ’MECHS":
"ICE-powered ’Mechs must make Fuel Explosion checks when their heat levels exceed 19, 23 and 28 points. The target number to avoid these explosions is the same as that required to avoid ammunition explosions at those heat levels." (emph. added)

Afraid I don't know whether to read 'exceed 19'  as '20+' or if 'at those heat levels' means 'AT 19 like ammo explosion rolls'.

Thanks!

Good catch.  It should say "reach" rather than "exceed".
