At Anfield, Sami Hyypia's opener, a Steven Gerrard penalty early in the second-half and a late Ryan Babel tap-in completed the scoring for Liverpool, but it was Torres that made the difference with his pace and determination.
Liverpool dominated the early stages by utilising the flair of Harry Kewell, Yossi Benayoun and Torres to negate the visitors' physical game-plan.
Hyypia opened the scoring on 17 minutes when he lost his marker Abdoulaye Meite to head Steven Gerrard's free-kick into the net from 12 yards.
Nicolas Anelka missed a golden chance to equalise on 38 minutes when he had an open goal at his mercy after a collision between Jose Reina and Jamie Carragher left the Frenchman free inside the penalty area.
But remarkably, Anelka aimed his shot into the side-netting when it appeared so much easier to find the net.
Torres later showed Anelka how to finish when on the stroke of half-time he escaped defender Lubomir Michalik before clipping a right-foot effort past keeper Jussi Jaaskelainen from a narrow angle.
Considering Liverpool's dominance, that was as good as game over for Bolton and they continued to be over-run by the home side in the second-half with Gerrard netting from the penalty spot on 55 minutes following Meite's clumsy foul on Crouch, before Babel completed the win with a close-range strike five minutes from time.
Birmingham stun Spurs

In Sunday's late match, Alex McLeish, new Birmingham manager, started his English Premier League managerial career with an unlikely victory as the Blues defeated struggling Tottenham 3-2 at White Hart Lane.
Birmingham took the lead in the 23rd minute thanks to a Gary McSheffrey penalty after he had been fouled by Younes Kaboul in the area.
However Spurs hit back after the break with Robbie Keane scoring a penalty of his own in the 48th minute after Johan Djourou tripped Dimitar Berbatov in the box.
Keane had his second just five minutes later to put the home side up 2-1, but Birmingham struck back through Cameron Jerome in the 62nd minute to level the scores again.
Two-goal Keane then turned from hero to villain when he was sent off with a straight red card for a late challenge on Fabrice Muamba in the 67th minute, reducing Tottenham to 10 men for the final 23 minutes.
Birmingham could have been content with an away point, but a stoppage time scramble saw Sebastian Larsson unleash a screaming right-foot shot from 28 metres out that left Spurs keeper Paul Robinson with no chance as it rocketed into the top right corner.
The win saw Birmingham leapfrog Tottenham into 12th place, with the under-pressure Londoners falling to 16th with just 12 points from 15 games.
Manchester United host Fulham on Monday night to complete the round of matches.
