One of the primary functions of coolant is to regulate heat within the cylinder head and engine block of your diesel engine. The coolant system is designed to circulate a cooling medium which absorbs heat from the engine and disperses it through a heat exchanger (i.e., a radiator or cooler). In the most basic terms, coolant picks up heat and transfers it to the radiator. Coolant is also used to protect against freezing and boiling, corrosion and pitting of cylinder liners and the diesel engine block. At Absolute Repair, we advise customers on industry best practices to maintain their coolant systems and prolong the life of their heavy-duty vehicles.

The suspension system of your heavy-duty truck provides your vehicle with a cushion against the shock and impact of the road surface.

A suspension system that functions correctly helps stabilize your truck, minimizes uneven tire wear, smooths the ride, and maintains the proper axle spacing and alignment.

Worn, deflated and flat tires can be a serious threat to getting your work done quickly and more importantly to your safety on the road. Realistically, fixing a flat or servicing an old tire is just part of life on the road.

You need a professional diesel mechanic to determine the best plan of action for repairing or replacing your tires. The team at Absolute Repair can help determine the best approach to either repairing or replacing your tires.
Transmission & Clutches
With so many different makes and models of diesel trucks and machines, there are varying clutch and transmission designs and systems.

At Absolute Repair, we believe that it is imperative to have a preventative maintenance plan which includes transmission and clutch service and adjustments according to the manufacturer's specifications in order to keep your truck running safely and securely.
While on vacation recently we unfortunately encountered a broken axle on our travel trailer. Being from out of town and the fact that it was a Sunday evening we had no idea who to call for repair. The tow truck driver recommended Absolute Repair and we were towed to that facility. The tow truck driver notified the owner of Absolute Repair that we were in their parking lot. On Monday morning we were greeted by Andrew who evaluated the situation. Peter (the owner) and Andrew were very easy to work with and kept us informed of their efforts to secure a new axle. Once they had the axle they worked quickly and diligently to put the new axle on the trailer and we were back on the road late Monday afternoon. Peter himself worked with another tech to complete the repair. Peter and Andrew are both very knowledgeable, explaining in detail the repair, as well as being concerned for our comfort and offering us the use of their lounge. The repair price was very reasonable. Andrew even placed a follow up call to us the next day to make sure everything was fine with the trailer. We cannot speak highly enough of this company and would recommend them to anyone without hesitation. Our sincere thanks to Peter and Andrew for assisting us and getting us back on the road so quickly.
