Thread: Disco II TD5 steering pump query

Could possibly be the exhaust manifold warped and leaking - it makes a sound just like a slipping accessory drive belt. Check for broken exhaust studs and missing nuts and black exhaust stain. No 5 cylinder exhaust port is usually the first to leak.

I don't know normal resistance in the disco pump, or how to express in testing terms, but discoloration may indicate an issue. Power steering pumps usually turn with only little resistance.

Have just been out and checked exhaust manifold and all looks good thereThe steering pump pulley definitely looks as if it has been really hot and there is rubber left behind from the back of the belt.
I think it is time for a new pump.
Has anyone any ideas on a good place to buy one?


Thanks for the help so far
Devo

Have found out the problem.It is definitely the steering pump. Now that I have put it all back together the pump is screaming.
Have picked up a new pump and that spins freely.
All going again


Thanks to all

Hi devo,
I just wanted to say thanks for your post, I believe I am having the exact same problem! The pump pulley does not spin freely like the other pulleys, it has a bit of play where you can rock it from side to side but it doesn't spin freely (if that makes sense).

I will arrange a new PAS pump and report back
