1998 BMW 840Ci

Replacing the damaged BMW 840 radiator

We were informed of a water leak on our 1998 BMW 840CI the day before she arrived in our workshops so part of our task was to identify the issue and rectify where necessary.

As a short term fix and to enable to vehicle to reach our workshops safely, the customer applied Radweld into the system. Radweld repairs holes caused by damage and corrosion. It has been specifically designed not to block channels and clog radiators. Radweld will target small leaks in your radiator without causing blockages.

With the car successfully in our possession we can now look to the cause of the problem and address the issues first hand.

Upon removal it is clear to see the bottom of the radiator shows damage. With the radiator removed we can now call upon the assistance of our good friends at Sheldrake & Wells.

2 days later they arrive with a brand spanking new one for our project. Sometimes it’s good to look around. It’s very easy in the classic car world to assume that parts can not be sourced and therefore the only way to overcome an issue is to repair what you have. This is a great example that not all components need to be rebuilt, some are still available and on the shelf.

…and a much more cost effective solution too!

Undersealing our 1998 BMW 840Ci

Some very questionable repairs have been carried out to the underside of the spare wheel carrier so we’ve stripped the entire area back to reveal exactly what needs to be done to put it right. Fibreglass had been applied over the corroded areas which is only a short term fix and is not recommended.

These repairs will be carried out properly prior to the entire underside being stripped, cleaned and sealed. The corroded areas will be cut away and new metal will be secured back into position. This is the only way to properly tackle the spread of rot.

The newly rebuilt BMW shocks have arrived in the UK

Rebuilding the BMW 8 Series shocks are a very specialist skill so we called upon the experts over in Poland to help us out on this one. The results are incredible.

The Nagengast company is a Polish enterprise operating on a European wide market, which has specialized in regeneration of automotive parts for 35 years.

Main activities of the company:

  • regeneration of shock absorbers
  • regeneration of bellows (pneumatic shock absorbers)
  • regeneration of steering transmissions
  • regeneration of power-steering pumps
  • regeneration of gas springs
  • manufacture of electric spring extractor
  • sales of new, specialist parts for pneumatic and adaptive suspensions

And now we have them successfully fitted to our BMW.


Refurbishing the front and rear suspension

[vc_row][vc_column][vc_column_text]Work has commenced on the refurbishment of our 1998 BMW 840Ci front and rear suspension. The shocks are to be sent away to Poland to be completely rebuilt but whilst removing the shocks we have uncovered a few unexpected issues.

The splash shield is severely corroded on the near side which will need to be replaced.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_video link=”https://www.youtube.com/watch?v=SDWc6SvVKnU” align=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]The springs, hubs and ABS sensor now need to be removed before the set up can be sent away to Nagengast in Poland for the full rebuild.


1998 BMW 840Ci suspension refurbishment

Our 1998 BMW 840Ci is currently in the workshops to have the front and rear suspension removed to be refurbished.

Whilst in with us we’ll also be looking to address a couple of smaller issues too; slight leak to the coolant system and the headlining is starting to drop too.
