Hello everyone.
Hmmm, I have found two locations in my AU Series II that have leaks. One is from a hose above the alternator and the other is a leak from one of the hoses going to the Thermostat housing unit from the radiator header tank. I have uploaded photos to assist with the diagnosis. All hoses are new and replaced radiator surge / header tank with a new one. Is it possible for these hoses to s**t itself so quickly? Anything else needs to be done apart from replacing these hoses again? Cheers

Diagnose?
The cars not a brand spanker! 3/8 Thermostat hose looks like an original to me so thats 10+ years old. Lower radiator hose looks to have swelled around the water pump inlet. Id advise to Replace the hoses, thermostat and use Larger clamps (width).

If the hoses were indeed replaced...did you also replace the hose clamps? Hose clamps can also suffer fatigue and is always a good idea to replace them with the hoses. Only an extra buck or 2.

the bottom radiator hose dont look to good.. it looks like its bulging just after the clamp..
and for the top hose on the thermostat housing, just get rid of the stupid spring clamp and replace it with a screw clamp.. |

what is the condition of the water pump intake? if its corroded the hose wont seal.
For the same reason check the condition of the little tube in the top of the upper thermostat housing.

have you recently filled with glycol and if so how much ? too much glycol based anti freeze will leech out of the pores of the rubber..

Many thanks for the responses to my problem with leaks.
I had installed a new radiator at the time when the new radiator hoses were fitted. The radiator hoses in question was purchased from Supercheap at Underwood. Hose clamps were not renewed so I used the same ones instead of new ones. The lower radiator hose looks like it's swelled because there is a lip (raised edge) on the original water pump an it was a pain getting the new hose to fit correctly, I used a bit of butter to provides lubrication to slip it over. The system as far as I am aware of has not been flushed, perhaps it might be wise for me to have this done. Coolant is correct grade and to specifications. Filled to the Max line so its not overcharged. As for the hose from the header / surge tank to thermostat housing, I will replace the entire hose and change fitting to a screw thread type . Thermostat housing originally had a lot of scale near the lip previously, this was cleaned back to good metal using wire brush. I would think the thermostat housing is still good |

the 'max' line is the 'hot' line which is where it should be when it's hot, if you fill to this line when it's cold it's still not a problem because it will purge off the excess...an 'overcharged' cooling system is usually as simple as a failing cap.
I'm refferring to glycols ability to pretty much travel through anything porous including rubber. Although since it's filled to spec it can't be that i guess... i personally don't see the need for glycol in australia unless your in areas that regularly freeze. It actually reduces the medias ability to transfer heat.... that and it's banned from race tracks because it's deadly slippery when its on the tarmac...

Oh ok, I was not aware that the Max line is a measurement for when its' hot.
I would have assumed minimum means minimal amount and maximum is just it. the maximum amount of fluid. Off topic. Power Steering pump, there are two measurements, hot and cold. How do I know if the power steering unit needs topping up. Is it measured when cold or when hot? Cheers |

Yeah I thought the same thing, until I realised that everytime I filled it up to the max line it would blow some off. As for the power steering. The level should be on the 'hot' line when the fluid is hot and on the 'cold' line when cold. I check mine when cold.
