The new Ford Ranger and Mazda BT50 engines have several common problems.

Common Faults:

  • Faulty EGR cooler
  • Blown head gasket
  • Holes in pistons
  • Leaking Diesel injectors
  • Turbo Failure

EGR Coolers:

We have tested several EGR coolers that have failed, which can result in filling the exhaust up with water, creating lack of water in the radiator resulting in a blown head gasket or engine failure. We can pressure test your EGR cooler to ensure it has not failed. Our pressure tester simulates working conditions. We carry out two tests, the first test we pump cold fluorescent coolant threw the EGR assembly and increase pressure to around 18 PSI which is above normal operating pressure and hold it for at least 15 minutes, while using a fluorescent light and check for leaks. Our second test we increase the coolant temperature to around 90 degrees while under 18 PSI of pressure to simulate operating temperatures. Sometimes the EGR cooler assembles can leak only on the cold test, and other times on the hot test. While we still recommend replacing your EGR assembly even if the test passes. The testing procedure can only let you know if you have a current fault, it can not predict a failure down the track. Due to these EGR assemblies are common to fail the cost involved to replace out ways a severe engine failure due to a failed assembly.

Why would you recommend to test the cooler if you are going to replace it anyway ?

  • If you are trying to find your water, coolant loss you need to know where the problem lies. It is no good just to replace your EGR cooler assembly without knowing if that’s what caused your overheating or loss of water issues. If we test your EGR cooler assembly and find no current faults, we then can let you know your water loss is due to another cause, which we would need to investigate. Water loss can be from a number of areas, It can be as simple as a leaking coolant hose, leaking radiator, or more severe issues such as a blown head gasket or cracked cylinder block etc etc.

Head gasket Failure:

Head gasket failures can be caused by several factors, A faulty EGR cooler, Blocked or leaking radiator, leaking or burst cooling hose, sticky or failed thermostat etc. etc. Usually the vehicles we replace head gaskets on are from poor or incorrect maintenance. We recommend a full inspection of your cooling system on regular service intervals. UMR Engines at Slacks Creek – Brisbane has all the machines to carry out your repairs to your cylinder head.

Diesel Injectors

Ford Ranger P5AT injectorsHoles in pistons are generally created by failing injectors, When these injectors fail they can result in a cutter torch like action blowing a hole in the top of the piston. We recommend to recondition or replace your injectors at 100,000km. We suggest when the injectors are removed to recut your injector seat to ensure a perfect seal. Compression can leak past the injector copper washer if the seat service is damaged or warped.

Our qualified diesel mechanics can service, test or replace your diesel injectors, We always recommend to replace your fuel filter at the same time, and to replace your washers. Our trained diesel mechanics can diagnose diesel problems, using latest diagnostic scan equipment, UMR Engines is the place for all your diesel repairs and maintenance.

 

 

 

Warning – while doing an oil change

Engine failure after service, can be caused from while draining the engine oil, if you take over 10 minutes to replace the engine oil you run the risk of the oil pump draining back, which can result in the oil pump not to re-prime.  Ensure your drain time is less than 10 minutes to prevent engine failure.

Turbo replacement

Is your vehicle lacking power or boost ?

We can Sand in the intake systemreplace your turbo using a quality genuine Garrett turbo used by Ford. We recommend replacing your oil & filter, inspecting your air filter system and clean or replace your oil feed line. It is very important to clean your oil feed line running to the turbo.
