WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.

"This is a must for all Cummins! It’s a really super install with the transmission out! Lower coolant temps dramatically while towing! Thanks DPP for the recommendation! Service team is knowledgeable and extremely helpful"
"My freeze plug ended up getting pushed into the water jacket. I pulled the motor and had it fished out in no time. Cleaned up the area really well prior to install. Installation was even easier since I was sitting on the transmission. It's a shame to hide such a beautiful part at the back of the motor."
"Cures a problem."
"I had already blown the rear freeze plug and only needed to clean the surface area to install the kit. The rear thermostat fit perfectly and the hose running to the front was the perfect length. Easy 1 hour or less install. It takes a bit of getting used to both thermostats opening at different times but it works very well and helps keep the engine just a bit cooler. The real test will come in the summer."
"After a phone call from customer service and a careful investigation , I discovered that this item did ship and arrive on time . The joker's at work thought it would be fun to hide it from me. I retract what I said about this company in the previous review and apologize. Diesel Power Products have been awesome everytime I have dealt with them and will continue to trade with this company. Dennis"
"Everything installed fairly easily , except for the left side bolt. I had to install and tighten from under the truck with a long extension. I have this product 4 stars because it came with hose clamps and Allen head bolts I couldn't use , otherwise it outstanding . Temp while running down the highway has dropped a few degrees , at idle there is a noticeable drop"
"I had a mechanic install. . This site has it the cheapest priced aswell"
