yes, coolant has been fresh and changed.
that's the first i've heard of heater hoses on this car.... and i've been on these forums for years. is that common? or just a general situation?
thanks.

There are heater hoses on every vehicle with a heater.
They are needed as the engine rides on flexible mounts and the heater core is mounted solid. The engine mounts wear and the added movement of the engine may stress the hoses high on the firewall, furthest away from the mounts below the engine.
The heater core and radiator should be in good shape with the coolant changes. Hoses tend to disintegrate from the inside out as they age, weeping at the hose ends. This includes the lower radiator hose.
Do you detect any fluid leaking under the vehicle after it is parked?

I once had a coolant leak from the "water seal plate," located on the bottom right side of the engine of my 91 LS400. It may be worth taking a look there. With patience, I was able to repair this myself by removing it, cleaning the mating surfaces with a plastic scraper, and applying black sealant, allowing it to cure for a day before refilling the cooling system. See the attachment for the location.

Hello,
no wrong there was no residue around the cap or the sensor. There is a small hose which ends infront of the drivers front tire. This is where the water can leave the coolant reservoir. You can check if there is pressure on your cooling system by opening the cap when the car is hot, but be careful you might get burnt.
