Image Credit: Hagerty / YouTube.Steve McQueen is usually associated with much faster machinery, from Mustangs to Porsches and motorcycles. Hidden away for years, however, was a far humbler vehicle carrying the same remarkable provenance, namely his 1942 Chevrolet pickup.The old Chevy had been preserved rather than abandoned, leaving it in surprisingly presentable condition despite its long spell off the road. Its mechanical condition was another question entirely, though, especially with just one day available to make it drive again.In a new episode of Hagerty's Driveway Finds on YouTube, hosts Brito and Dustin were given the chance to revive the truck and take it back onto public roads. Hagerty describes the pickup as having sat for roughly 20 years, although the hosts mention about 15 years during the episode.AdvertisementAdvertisementGetting a decades-old truck running is usually enough of an adventure on its own. Doing it while trying not to damage a vehicle once owned by Steve McQueen understandably raised the stakes.McQueen's Chevy Was Surprisingly Well PreservedImage Credit: Hagerty / YouTube.The truck's history after McQueen is unusually well documented. The current owner's uncle, Les, bought it in 1979 simply because he needed a pickup, not because he was chasing a celebrity-owned collectible.Fortunately, the family kept the documentation tying the Chevy to McQueen and preserved the truck carefully. The hosts noted that without those records, it would simply be another nicely kept wartime Chevrolet pickup rather than a vehicle with significant Hollywood provenance.Under the hood sits Chevrolet's 216.5-cubic-inch inline-six. The truck had also been converted from its original six-volt electrical system to 12 volts at some point in its life.AdvertisementAdvertisementThe condition immediately offered some encouragement. The oil appeared fresh, the engine wasn't seized, and even the old fuel smelled far better than the hosts expected after such a lengthy period of inactivity.The Straight-Six Didn't Need Much ConvincingImage Credit: Hagerty / YouTube.The team first made sure the engine could rotate before attempting to start it. They then worked through the basics, checking the distributor, cleaning the ignition points and rotor, verifying spark, and priming the lubrication system after initially seeing no reading on the oil-pressure gauge.Fuel was another potential problem, but what came from the tank looked relatively clean despite having some discoloration. Once fuel, spark, and lubrication were accounted for, the team added a little gasoline to the carburetor and tried firing the Chevy.The 216.5-cubic-inch six came back to life without much drama. After some attention to a slightly sticking throttle and carburetor, the engine settled into running with roughly 30 psi showing on the oil-pressure gauge. That was only half the job, though. An old truck that can start isn't particularly useful if it can't stop.The Brakes Needed More AttentionInitial inspection suggested somebody had previously worked on the braking system. The rear components looked particularly fresh, while the master cylinder appeared clean inside despite being dry.AdvertisementAdvertisementCloser inspection eventually revealed problems with a front wheel cylinder and, more importantly, a leaking master cylinder. Dustin had fortunately sourced the correct replacement beforehand, allowing the team to install it and bleed the system within their one-day deadline.The result was considerably better than expected. With the repairs completed, the hosts described the brake pedal as one of the best they had encountered during a Driveway Finds revival.Once the hood went back on, there was little left preventing McQueen's Chevy from moving under its own power again.Steve McQueen's Truck Returned To The RoadImage Credit: Hagerty / YouTube.Driving the 1942 Chevrolet proved to be a very different experience from the performance cars normally connected to McQueen. Its old transmission required double-clutching, the mechanical noises were impossible to ignore, and the hosts repeatedly compared the experience to operating a tractor.AdvertisementAdvertisementNone of that diminished the occasion. The truck maintained around 30 psi of oil pressure during the drive, its newly repaired brakes worked properly, and a temperature check showed it running comfortably cool. After sitting for roughly two decades, Steve McQueen's old workhorse was running, stopping, and driving again.The hosts also began wondering what McQueen's ownership could do to the truck's value. They estimated that a comparable Chevrolet might ordinarily be worth roughly $15,000 to $25,000, while speculating that McQueen provenance could potentially push this example toward $75,000 to $100,000.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
