The hoses seem fine, the fans turn on, but I seem to have a lot of coolant
leacking from the passanger side of the the engine. It seems to leak more
as soon as I turn the car off. Could it be the water pump? How hard is
that to change? Thanks in advance.

Look under the water pump pulley remove the belt and move the pump shaft
around see if it has play, some by pass hoses in this area also.

My 95 Olds 88 had a coolant leak from a bypass hose / belt tensioner near
the top of the engine on the passenger side. It's a small, right angle hose
that comes out of the intake, and connects to the belt tensioner. (3800
Series II engine.)

Or as another poster suggested, it may be the water pump.

Bob,

That is exactly the area where I think it is coming from. I'll take a look
at that. Thanks

I found where the leak is coming from. It is coming from a plastic
piece/pipe that broke off of the intake that the bypass hose is attached to
the intake. Is that a replacable piece? Where would I find something like
that?

Not being totally familiar with the newer 3800's I am going to suggest that
if they are like GM's other intake bypass tube a good parts store should
carry the part and just mentioning it they will know what you are talking
about.

I am not sure when the change was made, but verify whether your intake
manifold is aluminum or PLASTIC. If it's plastic be very careful not to
break it.
