Our internal engine services include:

Belts & Hoses
Timing belts and serpentine belts are the most common types of belts in trucks.

A timing belt (also referred to as the camshaft drive belt or the Gilmer belt) is a notched belt that allows the crankshaft to turn the camshaft. Failure of the timing belt would lead to failure of the engine. A loose timing belt could lead to its slipping. When slipped, valves will open at the wrong time putting them at the risk of being struck by the pistons. To avoid this, have your timing belts inspected and serviced regularly.

A drive belt transfers power from the engine to the front mounted accessories such as the cooling fan, power steering pump, air injection pump, the air conditioning compressor and more. Failure of the drive belt means that all the engine accessories it's powering will stop working leading to overheating of the engine. To prevent this from happening, have the belt regularly checked for wear, cracks and stripping.

Hoses (or coolant hoses) are the heater and radiator hoses (upper and lower). The hoses facilitate the flow of coolant between the radiator, engine, and heating block. Old and worn out hoses can easily burst resulting in an overheated engine. To prevent this from happening, have the hoses inspected for cracks.

For belts and hoses maintenance and replacement services, visit Protrans Automotive & Transmission Specialists in Riverside, CA 92507 today. Remember, working belts and hoses will lead to a properly working engine.

Cooling System
Although a truck's engine operates most efficiently at high temperatures, the surplus heat produced during combustion can damage engine parts. To keep the engine safe from the surplus heat, trucks come with a cooling system. The system helps the engine maintain the required temperature and release any surplus heat to the environment.

The cooling system is made up of various parts that work harmoniously. These parts are the radiator, fan, pump, pressure cap, hoses, thermostat, and overflow tank. Failure of any of the parts will result in a poorly functioning cooling system.

To have a properly working cooling system (and thus a healthy engine), consider having periodic servicing of the parts that make up the system. At Protrans Automotive & Transmission Specialists, we can service or replace (if necessary) radiators, fans, water pumps, hoses, thermostats and pressure caps.

Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:

  • Changing the oil & filter
  • Changing the air filter
  • Changing the fuel filter
  • Bleeding the fuel system
  • Draining the water separators
  • Refilling the urea injection system
You can count on the experts at Protrans Automotive & Transmission Specialists to help your diesel engine last a long time.

Engine
This is where your truck's combustion of fuel occurs. The ignition, which takes place in a combustion chamber, provides force to the pistons, turbine blades, or a nozzle. The engine provides power that drives your truck. With a poorly operating engine, you will have a poor performing truck. Visit Protrans Automotive & Transmission Specialists in Riverside, CA 92507 today, to have all your engine needs addressed. At Protrans Automotive & Transmission Specialists, we have engine specialists who will make sure you get the most from your truck's engine.

Exhaust
An exhaust system is a piping that directs exhaust gases away from the internal combustion engine to the outdoors. A truck's exhaust system is made up of one or more exhaust pipes. An exhaust system can be modified to increase engine power (and performance), reduce pollution, or reduce noise. Also, a properly operating exhaust system is required for operator safety.

To get the most from your truck, you need regular exhaust service. For exhaust repairs, exhaust modification, or exhaust replacement, call 951-367-7400 or visit Protrans Automotive & Transmission Specialists today.

Water Pumps
A water pump is a vital part of your truck cooling system. A water pump is a centrifugal pump that circulates fluid whenever the engine is running. A belt connected to the engine's crankshaft drives the pump. Water pumps have vanes that fling the fluid to the outside of the pump (using centrifugal force) where it can enter the internal combustion engine. After going through the engine and the cylinder head, the fluid flows back to the water pump.

If the water pump develops a leak or the hub becomes loose and noisy, you need to have it replaced. Faulty water pumps will lead to poor cooling of the internal combustion engine. To have faulty water pumps repaired or replaced, call 951-367-7400 or visit Protrans Automotive & Transmission Specialists today.

what our customers say

We've been going to Pro Trans for over 20 years & always have good experiences. I want to thank Michael for his personal service all these years. They've replaced engines & transmissions in two of our vehicles. There is no job too small or too big, so far. They don't even mind working on our raised truck with a 6 inch lift! Thanks again for your the great work!

I was nervous about finding a shop to work on my truck since there are so many shady mechanics out there, but Protrans ended up doing an amazing job. They were great about communicating with me throughout the whole process as well. I believe I paid a fair price for the repair and they didn't try to sell me a bunch of service that I don't need. I will certainly be using them in the future if I need to.
