I blew that hose once whilst driving.
I thought the engine was smoking but the engine was burning the coolant.
Vapor came into the cab through the vents.

I preferr heat to ac. If that dash weren't such a bugger. I'd delete the heater core.
But that's just me.

I had to give it a complete tune up.
I just changed the plugs, as I was not happy with my replacement choice.

I used the same wires. And in retrospect. I should have changed the coil wire as well.

I meant hard rubber at the connection perimeter. So, my bad.
The entire hose will NOT be hard. I thought that a given.

The hard shit has to be removed it will not flex it will crack and tear no telling how far.

Check your power steering pump res. hoses. I'd almost promise you those are hard at the connection.
I have a 91 and mine are frozen on. I dared not remove them. To keep them from cracking and splitting.
That's all I was trying to say. I probably should have elaborated.

All of these cars have the same shit wrong with them in different ways which is what makes problem solving such a riddle.
