book calls for 4 hours
3-4 hour job could be done in as little as 2 hours
Yhea obviously those that have answered with book time don't work on vehicles... your forgetting the corrosion (oxidation) that occurs on the front of the engine, not to mention the possibility of a broken bolt, or that the harmonic balancer has been on for 15 years might need some extra persuasion to come off which would mean that the radiator has to come out, or clean up time of all parts before re-installation (you ever try and just wipe off a 15 year old gasket?) but least of all road test time to ensure that all repairs are done correctly. book time is for the actual time of the steps involed in a perfect situation with hand tools. can it be done in
yhea the book says... god i love that answer!
