Never have seen one fail yet. Something punctured it or it was defective. Its not that hard but its not easy. PS pump needs to be swung back, upper bracker moved and then the water neck from the pump to the head needs to come off. Then the hose can be removed. Probably removed the dipstick tube while at it and plug the hole at the oil pump while working above it.
Hose behind the water pump
1996 Corolla,1.8,113K miles
Has anyone replaced this hose before? Its about 1-1/2" in diameter and looks like a PIA to replace!

I replaced mine when I did the cambelt and waterpump. The old one still looked fine, but I felt that it was better to be safe than sorry, especially since it only cost a few dollars from Toyota
So? Honda D and B series 1.5, 1.6, 1.7, and 1.8L engines have a much simpler cooling system design IMHO. The lower radiator hose goes up to the thermostat housing on the rear (transmission end) of the engine. The thermostat housing also contains the coolant temp sensor. From there, there's a pipe running along the back side of the block/head to the front (timing belt end) of the engine. There are various coolant hose ports on the pipe, depending on the model of the engine. Then the water pump itself just bolts to the block, and that's that.These are FWD designs after all
One thing I don't like about those Honda engines is the oil filter being on the back side of the block, but oh well. I guess the fact that you can remove the water pump without removing the timing belt is cool on the 7A-FE, even though you should replace them both at the same time.
Oh yeah the 2-piece oil pan design on the 7A-FE with some bolts being hex head and some being allen head is just so pointless IMHO.

There you go. Some manufacturers handle their FWD designs differently than the others, as your post pointedly pointed out:} By the way, maybe Honda did this since it is critical the TB is replaced so that the engine would not be damaged if it did. Good way for them to cover their butt.
well that's another thing about the Honda engines - they're interference design so if the TB breaks usually valves get bent or worse, whereas Toyota engines are non-interference design (most of them anyway I think).
But I still think it's easier to work on my Integra than the Corolla is.
