I have been battling with replacing my crappy factory speakers in my 92 740TI. I originally tried a set of Power Accoustik speakers I pulled from my wrecked 240 but they are too deep. I then went to Circuit City and got a set of Bazooka El (I got 5.25 for the rear, 6.5 (is actually 5.25) front door, and I am poor so I have to wait for the 3.5 in the dash), those don't fit right either. While I was leaving I noticed a puddle of coolant under my car, the bottom radiator had burst.
Nonetheless I am pretty frustrated. I would just put the factory ones back but I drove a screwdriver through each one several times trying to free them from the rivet. If Volvo could have only made the radiator hoses out of the same material they made that rivet out of. I filled the radiator up with water and left the cap off. I then stopped to check and refill. I made it home ok.
Anyway my question is what are the likely failure points in the cooling system? When cold no coolant leaks but when hot the coolant pours out. I figure it is the bottom radiator hose since it is liquid and not steam. I will probably replace both bottom and top hoses are there any other places likely to cause such a leak? Is there anything else I should do post over heat? I will also change the oil anything else?

You are, unfortunately, at the end of the lifetime of the entire cooling system. You will have to replace both radiator hoses, the reservoir hose, the heater hoses and water valve, and the radiator itself. The radiator plastic becomes embrittled and breaks catastrophically: its lifetime is only about eight years. If you buy the components aftermarket from FCPGroton or the like, plan on spending about $300. This is the price of peace of mind. If you don't do this, your cooling system will collapse and the engine will overheat.

Hi Steve,
Happy New Year. The radiator is new (nissens) but I don't think the hoses are, those will get replaced. Is the water valve the thermostat or is it something else? Where are the heater hoses? Are the heater hoses for the cabin heater?
Thanks again.
PS This is a new car to me I've owned for about a month. I bought it at a dealer for 1500 dollars. It's a 1992 740TI with only 108K. It is in really nice condition but it has the typical piston slap, hence the stupdily low price. I knew it would have some quirks.
