Heater Hose Question
1990 L98 w/ oil cooler. I am in the process of replacing a leaky water pump, and I wanted to replace the heater hoses. The hose that runs from the expansion tank to the wp seems to have a really large (1") size coming out, but then goes down to 3/4" were it splits to run to the oil cooler. I can see that this is a formed hose, but is it still available? If not, what did you use to replace it? I thought I could just use 3/4", because thats what "tee" fitting is. any ideas/suggestions?
Thanks in advance.

If the hose is in good shape, i wouldn't bother. That hose is a PITA.
my car is an 89 with 126K miles on it.. the only hoses I have replaced are the upper and lower radiator hoses at some point. Most of those hoses can go the life of your car.
If the ends are dried or cracked, sometimes if you have enough slack, you can shave the end off and just pull it a bit tighter and clamp it back on.

The hose should go from the water pump to the heater core. It has two tee's along the way: one at the oil cooler pipe and another at the steam vent pipe. It is available from GM for about $100.
The original had molded tee's so that it was all one piece. The new GM part has two metal tees in it with clamps all around. If you decide to replace all of the hoses, don't forget the two short ones near the oil filter.

It is now $150.00. Someones got to have one cheaper, any ideas?
My hose has a crack in it that has been leaking antifreeze.
Ok, so NO ONE has every had to replace this hose on there car?
I find that hard to believe. At this point, I would just buy a hose that comes from the surge tank to the water pump, even if it's for an LTx car, I just need a hose that will fit onto the opening on the surge tank.
Any help?

Ouch...
and nope.. if it ain't broke, most of us don't fix it.
Let me ask you this.. where is the hose cracked?
I have done this in vehicles before with great results: Just cut the hose where its cracked, get a connector and clamps and a new length of hose you need to reach where ever it is going.. shouldn't cost more than $10. Then just cut the hose where it is cracked and add the new hose in.
If the T connector area is cracked, then find one with the correct size openings, cut the old one out, splice the new one in (along with any new hose length you will need).
When my heater core went, I just cut the hose, plugged it, got a 4ft length of heater hose at the auto parts store and routed it back in place so the coolant could flow. Cost me $4 total to fix that.
hose and clamps are cheap, you just have to be creative
Remember, its just a car with regular hoses... you don't NEED the "fancy corvette only" stuff in most cases and can get away with making many other things work.

I hate having to do things twice.
Thanks, Randy
