Do pas pumps sieze?

[NeilH]

I was driving today - 93 200tdi and I kept getting an intermitent squeal (belt slipping) and at the same time the ignition light would come on. It came and went over the 10 mile trip.

When I investigated, I found the pas pump was too hot to touch. I'm thinking perhaps the pump is siezing up, the sqeal was the main belt slipping and the ignition light coming on as the alternator stopped turning as the dual pulley is on the pass pump.

Does this diagnosys seem likely? Has anyone heard of a pump seizing before?

Thanks
Neil

Hi Neil, yes, it does sound very likely.

I had this on our first Discovery, a TDi 200. It was making a chirping noise at first, hoped it would get me home, but no !!!

At 11pm, in the rain, on the A20 just south of Orléans and still 200kms away from home, the pas pump seized, blew the belt, so everything else stopped working and I had to get dragged off the motorway and parked up in a little village in the backwoods somewhere.

Fortunately I had my bike on a trailer, so I rode that home. Got home at 2am, frozen and wet, but home.

I didn't know anything about LR spare parts at that time so I let the garage fix it - 700 euros later - I went and collected her. O deep joy :(:( Now I know how much the pas pump could have cost me and how easy they are to fit, it makes me weep. £124+vat from Paddocks.

Thanks for the reply. It all seemed to make sense, but I was just a bit unsure about a simple pump that's full of oil seizing up. But if it's been known before then I'll take the pump out tomorrow and have a look.
