Drip Drip Drip

I was under The Beast today looking to see if I could find the location of a stray part from Marv's PPV and I noticed a wet spot.

Dang.

There's a seeping at a Tee in the upper radiator hose.

I can't tell if it's the ends of the hoses, the Tee or the line going to the oil cooler.

The hoses look to be original 13 year old, 165k mile items, so I looked to get replacements.

Gates and Continental make affordable upper hoses for both sides of the Tee.

There's no aftermarket replacement for the oil cooler hose.  GM wants $95 for this part.

It's about a foot long, has a small dog-leg in it and in typical GM fashion, one end is 0.60" ID and the other is 0.77" ID.  SIGH.  I guess one could use a length of 3/4" heater hose to replace it and hope the dog-leg doesn't matter.

Then there's the matter of availability.  I can't single source all of the pieces.  I hate dealing with multiple shipping costs and speeds.

But, when it's all added up, I got $178 for the complete upper hose assy with new tee, some 3/4" heater hose to replace the line to the oil cooler and a lower radiator hose.

With delivery dates ranging from tomorrow to mid-October. 

OR

Order a complete set of everything for $250 that's made from silicone instead of rubber.  This even includes some small steam lines not addressed by the $178.

Neither plan addresses the lines to the heater core, but I have an expensive plan for those too!

The silicone hoses are in a spiffy electric blue, so there's that!
