Hi,

My heater hoses are original and I want to replace them. I want to make sure I'm getting all of them. So, here is my list of all of my coolant-filled hoses...am I missing any?

1. Upper and lower radiator hoses
2. Hose A and B, water inlet
3. Hose, water outlet
4. Hose, bypass inlet

I am using the terms from the Majestic Honda diagrams.

Thanks,

Roy

 

If you are looking at the parts site, here are coolant hoses:

17, 16, 5, 6, 4, 10, 7

Some are smaller hoses. I wouldn't replace them unless their connections are getting brittle and cracking.

 

Thanks PA,

That is just what I need to know.

It seems pretty odd that small hoses called, for instance, "fast idle control hose" have coolant in it. But, it is probably only odd because I have no idea about how things like "fast idle control" work on this car.

FITV = fast-idle thermo valve
That thing, bolted to the bottom of the throttlebody, allows extra air into the manifold to increase the idle RPM when the engine's cold. As the coolant warms up the FITV closes off, dropping the idle to normal.

 

Thanks, Jim.
