While towing a U-Haul trailer, my Dodge Ram 3500 Cumins Diesel blew the water pump. Suddenly no power steering or brakes in the middle of California looking pretty desolate. We made it to the next stop which had a gas station and at the top of a hill across from the station there was this little building that said diesel and truck repair. We made it up the hill with the owners help. The serpentine belt had also come off. Fortunately the belt was still in one piece. An hour later a new water pump and belt were delivered and everything was repaired and we were back on the road with minimal delay. The service, experience and helpfulness of this business was top notch. Thankful that we broke down here. read more

Two thumbs up does not give credit to this salt of the earth team at Precision Diesel. This family owned, lonely looking settlement at the top of a hill off Interstate 5 at Westley exit (45 minutes south of the 580 Fwy) is equipped with top notch mechanics and a facility that repairs and custom fits hoses, tires and the like for diesel trucks and trailers. The majority of their customers are big rig diesel truck drivers. Driving home last summer (late morning) on the I5 from San Francisco in my 2003 VW Beetle, I saw that my car began to show signals of distress, OVERHEATING to be precise. If you've ever been on the I5, you're familiar with its endless stretch of road, scarcity of exits and scant signs of civilization. Being a young woman with car trouble in the middle of nowhere is scary. Not to mention the coin I imagined spending being a vulnerable civilian in the world of auto mechanics. Sure, I could call AAA, but there wasn't an exit sign to be found to pinpoint my location. I drove 22 miles, fingers crossed, with the hope of finding any kind of facility where human life could lend a hand. Most might say I was silly to keep driving, but I thank my lucky stars I did because my saviors awaited me at the I5 Westley exit. There was one standard gas station and a full service truck stop depot across the freeway, but I looked up a steep hill and saw a sign that read -- PRECISION DIESEL. Were they even open? If so, at best, someone could diagnose the problem. I slowly putted up the hill and was met hesitantly by Chris, a shirtless, tattooed, sweaty and handsome young man, with a long braided ponytail (he's a musician on the side and proud father of 2 little girls). His baseball cap was on backwards and he squinted at me. While I was sort of intimidated by his general malaise (it was about 95 degrees), I knew they were stuck with me for at least 5 minutes. An older fellow of the same ilk popped the hood to surmise the damage. Remember, they're used to big rigs, not pip squeaks. Yes, there was fluid everywhere, but he couldn't tell if it was an oil or water leak or both as the color and texture was mysterious. Chris approached and reached into the steamy innards at the front of the engine and after some inspecting and some pulling (and some suppressed anguish from the heat), he figured it out. The left fan at the front end came loose and rubbed a hole in the water hose. What to do next? Next, Chris' dad, Fred, (a Vietnam veteran who prides himself on talk of his parents, family, the business and his Harley) came to our huddle (they graciously let me poke my curious head in the engine with them -- I'm fascinated by auto repair) to look at the damage and chat me up a bit. What a character! He cracked jokes and gave fatherly instruction to Chris about what to do next, while Chris obeyed, knowing already that he would cut me a new hose to append to the odd-shaped VW version. In a matter of minutes, the hose was cut and conjoined with a clamp to the original hose and it was like new. To prevent a repeat performance by the offending loose fan, Chris tied it to the front end with hard plastic stays and voila, it was secure! To this day (6 months later), the stays are still intact and I haven't had a water leak. VW checked it out the week after and they said, "Looks good to us." Forget about taking me to the cleaners, after working for about an hour and a half, they graciously only charged me $50!!! What's important about this -- not being an aficionado on the actual cost of car parts, but rather an expert on being gouged by various mechanics -- is not that they were just being nice, but they charged me for the value of the problem (minus the labor, thanks guys). Do you know that the VW dealer in downtown LA charges a cool $85 to change a headlamp on this cute little bug?! Hmphf...AND they don't even let you watch. By the end of my fortuitous visit, I drove back home to Los Angeles safely and happily, knowing that my next excursion to visit my family in San Francisco will also mean a visit to Precision Diesel. Not because I'm a trucker or a gal with an auto problem who got lucky, but a friend who just wants to say hello and give thanks to the men atop the steep hill off the vacant stretch of the I5 Westley exit. read more

Very nice crew. Fast and friendly. Got our RV back on the road.

I was returning from Sacramento heading towards LA at the 5/580 junction when all of a sudden: "Thunk". Oh oh, the battery light comes on red, no power steering, the a/c is blowing hard at 105 degrees. Right in the middle of literally nowhere if you are familiar with the area. After the initial freakout I figured the engine seems to be OK, and Westley is right up the road. Over the years I have seen a little shop at the top of a hill on the West side that looks a little junk yardish but recently (in the last 5 or so years) a "Diesel Repair" sign has been put up (with a white cross on top). I went up there fully expecting to be turned away because I have a MBZ $printer and NOBODY works on $printers, and expecting to be told this is for big rigs only. Lo and behold, Chris and Russ are in there tinkering with an engine on a stand. I received immediate attention as there were no other customers ahead of me; Chris checked out the VIN and double checked to make sure it was a Daimler vehicle while Russ pulled out the shredded serpentine belt (the issue) and discovered the part number. Boom, on the phone goes Chris, within 15 minutes here comes the parts delivery guy from Patterson right down the road, and within 15 minutes my serpentine belt had been replaced! From the time of incident to back on the road was literally 1 hour. I was fully expecting to be told it cannot be repaired until tomorrow (my birthday BTW, just what I would NOT have wished for) and to have to spend the night in the Motel 6 across the freeway. Chris and Russ are two of the most awesome angels along the I-5 corridor to be able to drop everything on a moments notice to take care of an emergency (for me) situation and get me back on my way. Five stars to Precision Diesel in Westley! read more

We (Austrian family on a 3 weeks holiday trip from San Francisco via L.A. and Las Vegas up to Denver at the end of July 2011) suddenly had troubles with our Ford rental car some 10 miles before, just coming from San Francisco. The Battery discharge warning came on and the air-condition stopped cooling! So in this part of nothing, we saw a gas station and on a hill nearby a sign "truck repair"! It was already in the evening 6 pm, but they both checked our car and organized a spare belt from the city nearby... His dog jumped up on his pickup and 50 minutes later he worked already on our car. We had a break in the gas station with air condition and with nearly no delay we got back on the highway 5 and we had no more troubles with the car for the next 2000 miles till Denver!!!! Both the older and the younger guys were so friendly and they said "we leave no one on the road with a broken car" ... And that all for a very fair price!!!! Thanks' a lot! read more

Traveling from Bay Area to Long Beach New Year's Eve 2018. My son gave me this car while I was waiting for another and there was a family emergency and I had to drive to LB in this old but new to me car. 1 1/2 hour into drive I stop for gas and then the car starts making noise and starts to smoking. A female with zip knowledge of cars I was freaked the .... out. This gas station just of Hwy 5 was not a major one and had no one to help There was NOTHING around and car smoking and remember NYE, I was feeling hopeless and scared. I spotted up on a hill this place which looked alittle outta a movie. I breathed in and drove slowly up. I was greeted by a couple of dogs and a man. He had been working on something but stopped and came over to take a look. He said he was just about to leave but would check to see if he could find the parts. It only took him a few minutes to find out the problem, another 20 mins he found the parts however he had to drive into some town ( not one I could see in any direction) to get the parts. Chris had the car fixed and me safely on the road again in just under 2 hours. That day he was my Hero! If he had not been there or willing to help I cringe to think what would have happened. He was knowledgeable, friendly and Got it Done. Thanks so much Chris! read more
