Never ever will Bob Riley and his crew leave you hangin’. I had a problem with my 2002 Ford. Not really a big deal, but just needed a second opinion on how to properly do a coolant flush and also determine what length belt I needed on my truck. Technician Don was awesome. He found out what a cold weather package was that came as an option on my year truck. He wasn’t sure, but he promised me he’d find out and he came thru. It was important to know wether my truck had that package, because it determined the proper length fan belt(o did a whole coolant maintenance on my truck, which included new belt, hoses, and a T stat from Dieselsite). Last thing- Bob Riley was the voice back in the early 2000’s when he spoke highly of the importance of filtering the coolant on a powerstroke. I bought his original kit years ago, and am religious about filter changes. This last time, when I went to change the filter out I took it upon myself to open the filter up. If you saw all the crud and sand deposits like I had in my filter, you, too would be filtering your coolant. Bob sure made a believer out of me! Augie

I am very pleased with the service and quality parts that I ordered from DieselSite. Crystal took the extra time to inform me that one of the parts that I ordered was not necessary. She also saved me money on shipping and got the parts to me very quickly. The whole experience was the perfect example of a company that really cares about what they do. I will definitely be sending everyone that I can to DieselSite.

First rate service and products. Can’t go wrong.

Parts availablility, shipping speed, customer service is the best in the industry!!!

Everything I have ordered has been shipped in a timely matter and never have had any problems with anything I have ordered from dieselsite since 2008.

I first bought from Bob 7 years ago. I gave been a customer ever since. Keep up the good work.

Great products and fast shipping. I've ordered numerous products for my 7.3l Excursion

Fast Shipping and awesome Product

Because of your free shipping you blew everyone else’s prices out of the water. Thank you so much for providing a place to get great stuff at reasonable prices.

I love the quality of your parts, always an exact fit. Shipping time is minimal considering I live across the country from Florida. Always happy and excited to see the new parts show up on my door step. Confident in knowing I should never have to replace them again

They made ordering a breeze and they have fast shipping. Will do business again

Well made compared to stock stamped metal one.

I have a 2000 F-350 7.3L Diesel. They have many unique parts for my truck that you cannot find elsewhere; for example, waterpump with a built in filter, valve to put into heater core lines to make the air conditioning colder, etc. They have a transmission fluid external filter kit with a special valve to bypass a dirty filter. They are great people to deal with and support with your business. Thanks

Easy to order and quick delivery

The HPOP in my 02 Excursion needed to be replaced. After much internal debate, I purchased the Diesel Site Adrenaline HPOP - 96-03 Ford 7.3L. All I can say is - I AM GLAD I DID!!!! The entire process from purchase to the arrival of the item (very well packaged) to the installation, to the return of the core and credit, was absolutely flawless. Now the most important part - but first - I installed a brand new Bostech HPOP approximately 3 years ago. This was part of a complete engine overhaul. Once back on the road, it just wasn't running right. WOT was never an option because it sounded like pure metal on metal from the turbo. Enter the DieselSite Adrenaline HPOP (with CNC HPOP Lines). Welcome back WOT. Not a bit of metal on metal grinding. Significant (I mean significant) increase in power. I am afraid of the damage that has been done up until the installation of the DieselSite HPOP. I'll deal with that later. I learned the hard way. DieselSite - Thank you!!!! It is very hard to find quality products and even harder to find a company that isn't out to take me to the cleaners. Keep up the great work. DONT CHANGE THE BUSINESS MODEL!!!
