Replacing nested coolant hose
 

On my 1988 7M-GE, there are two hoses that feed into the thermostat housing, which then feeds into the upper radiator hose. Both are 90 degree formed hoses. The are aligned side-by-side: one is on the right and the other is to the left of it (assuming right and left refer to the car sides, ie, right = passenger side, left = driver side). The left hose runs underneath the timing belt housing. Unfortunately it is leaky! I have no idea how I'm supposed to replace that. It doesn't even look like a worm gear clamp will fit in there.

Any advice is greatly appreciated!!

Thanks to cre, I've got the coolant and heater hose exploded diagrams with part numbers (below). I'm getting ready to replace all the rubber lines, since I've now had 3 coolant lines pop leaks in the last year. It looks like the best way to replace both these 90-deg bends is to remove the thermostat housing. The fit is very tight, but removing the housing first looks like it will open up the space. Cut the existing hoses if you need to, then remove the cut hoses once the housing is off. Attach new hoses to the housing, then install the hoses to the pipes on the block as you reinstall the housing with a new gasket.

i was really hoping there was a way without having to remove anything...

Is this one of the hoses your referring to ?

yup, thats the bastard!

I don't know for sure, but from that picture it looks to me like you could release the clips, cut that hose & twist it off with needlenose pliers without removing anything & then a new one would be reasonably easy to fit, being new & flexible. Just make sure the hose clips are put on the centre of it first & perhaps clean the stubs up with emery paper &/or smear a little silicone sealer inside the hose ends first to make it slide on better.

thanks for the advice, but im guessing i couldnt reach in there not only because the fan is in the way, but i can barely reach a finger in there so i dont see how i could fit pliers or anything else in there!
