Heater hose keeps blowing?

I have a 95 Taurus 3.0L... The rubber hose between the thermostat housing and the metal line that goes to the water pump has blown twice in the last 6 months.. What could be the cause of this? also, the antifreeze was brown when I just fixed the hose a few days ago (i dont know bout last time because someone else fixed it), could it just be because the antifreeze might be old?

Re: Heater hose keeps blowing?

I would get a proper cooling system flush done.

Brown colouring means there is rust, and the system should be evacuated and refilled with fresh fluid.

As the hose keeps blowing off, as you mention, I would guess that there is a blockage or partial blockage in that area. The pressure builds up to the point where it has to be released - and blows the hose off. Or, the right type of clamp isn't being used, or used with enough force.

Engine coolant has a lifespan, which varies. Vehicles that utilize more aluminum components can go much longer on a coolant flush and fill as there is less worry of contaminants. Rubber also breaks down over time; hoses can crack and break under pressure or stress of heat/fatigue.

Worst case is that the heater core is on its way out. Most heater cores are constructed of steel and over time the coolant breaks down past a certain point and can rust the core.

A good way to check to see if a coolant flush and fill is due (other than rust/brown coloured coolant), is to remove the pressure cap (engine cold). If there is white residue settling around the base of the cap, that's another sign that you should get a coolant service done. The said gunk (or rust) can eventually form clogs that can stop flow in passageways throughout the block, and in extreme cases, hoses.

When you get the coolant flushed, be sure that the shop installs a new thermostat. Tstats are about $6-10 and more than worth the cost of replacement for what they can save you. You can get a Tstat that will remain open when it fails, so it doesn't starve the engine of coolant which can lead to overheating conditions (new heads for instance...).
