Low coolant, white smoke at startup, no milkshake

Recommended Posts

Picked up a super low mileage (45k) 2001, standard cab, V6. Of course there is a catch (at least hoping not that horrible of a catch)...Has some typical rust issues I am not worried about but...Low coolant and some white smoke at start up. Topped off coolant, after driving no smoke....Next day at start up, light amount of white smoke. Checked the Oil cap and dip stick, no milkshake...But, can smell coolant from outside vehicle after the drive and no leaks below. Otherwise runs fine.


With research I have read everything from head gasket, intake manifold, water pump, cracked block ,etc....


Any guesses with a low mileage truck used as a yard truck (keeping the miles low)?


Appreciate any insight or guidance on what to check.

Doesn't mean there is no leak, could be evaporating on the block before you see it. Let the engine cool, then restart engine and let it run just enough not to get hot. Then look around for leaks.
