Thread: Oil cooler system clean up and re hose.

Replaced oil cooler after catastrophic failure.Wondering if anyone has experience with the cleanup and whether all hoses should be replaced. Radiator has been flushed but when running burst a hose . No damage done only a dirty driveway. Other hoses look OK but think because of oil damage may need replace the lot. Is detergent ok for a final flush and does the thermostat need to open for complete clean up. Thanks

Have checked hoses they seem good , but I think Ill replace all and then keep the better ones for spares. Did do some checking and the dishwasher powder dosnt soap up so maybe if stuck it might be an option.

The head is made of aluminium, dish washer detergent has a high pH, it will eat away the aluminium. If foaming was the problem you could add a de foaming agent. The high pH will eat away the aluminium!!
