Bolt from exhaust? (3,3,2)

Ross

I believe the answer is:

run out of

'exhaust?' is the definition.
('run out of' can be a synonym of 'exhaust')

'bolt from' is the wordplay.
'bolt' becomes 'runout' ('run out' can be a synonym of 'bolt').
'from' becomes 'of' (I've seen this in other clues).
'runout'+'of'='RUN OUT OF'

I've seen this clue in The Times.
