heater hoses

[Wilma]

I am going to have to replace the two long rubber hoses which run front to back on my 1990 T.25. The original engine was a 1600 deisel but it has been replaced with an AAZ, though it looks as if the original hoses for cooling and heating were retained. What sort of a job is it? Seen from underneath I have the two large plastic pipes and, clipped to them with cable ties, two smaller diameter rubber ones which, I imagine, are the heater ones. They are beginning to show signs of breaking up, but no leaks as yet. I can see where they go at the engine end but have not yet investigated the front end which I cannot see. Is it necessary to drop the fueltank? Are these hoses the same diameter the whole length - if so will any high pressure hose do? Getting them above the fuel tank looks a bit of a fiddle but, apart from that, it looks straightforward job - is it? I have researched Wikki and the technical archives but there is not much on these hoses but plenty on the coolant ones.

umm id like to know this too .i can see two hoses going into top of matrix ,heater, but am also not sure if there 1 piece all the way or is there a join,i havnt really looked but take off the middle heating cowl/triangle bit/between driver passenger / floor u can see them coming in the top behind dash/but they look same diameter so i would say yeah a length would do .but i havnt looked proper,good luck.

later petrols are the same diammeter throughout

early petrol / diesels on one end (engine) on one pipe it flares out to a bigger bore to fit the head or output flange

are you sure these are cracking up? never seen them do that , some have paint/underseal on them that can crack due to age , but they usually dont have issues.

loads of good used ones hear.


yes you need to drop the tank to do the job properly.

a tank can be removed /refitted in 45 mins if all goes well!
