In this guide I will attempt to help anyone who needs to remove their EGR valve on a TTID 93 Z19DTR engine.

This was easy for me as a non mechanic and took approx 15 minutes to take off and replace.

What you'll need

Torque Set and Ratchet Size 30
Wynn’s EGR Cleaner
Optional New EGR Valve (Part Number 55209609) approx £120 - £200

Location

The EGR Valve is located to the rear right of the engine, you will need to remove the plastic engine cover and insulation.

There are 2 screws holding the EGR Valve that need to be removed. I have circled one in red that is easily visible from the top. The other screw is directly below the first on the underside of the valve.

There is also an electrical connection that needs to be removed. To do this the yellow clip on the orange connector needs sliding out as this acts as a lock, once pulled out in the direction of the arrow the orange electrical connector block will become free to unplug.

Once the blots have been remove and the connector you can pull out the valve for cleaning or replacing.

The above EGR was cleaned using Wynns EGR cleaner by the AA two days before I have written this guide so is not as clogged up as before. The cleaner is aerosol based and just gets directed towards the carbon deposits and eats away at it until clean. I presume any carbon cleaner will work, however this is the product that I saw being used.

I decided to proceed and buy a new part rather than see if the old one remained stable, it came with a new gasket and screws, however I didn’t have the recommended DOW CORNING for the gasket so I left the old one in place.

Fitting the new EGR is the opposite of removing and a simple process.

Hope that helps. p.s. if anyone has any comments or other tips to add to the guide please contact me.

hi take it you got the 2 fixings out ? a gentle tap towards the base may dislodge it, tbh it should not be stuck fast

were you suffuring with the limited performance light coming on, I am. I just stop turn the engine off, then restart, it runs for another 5 miles then comes on again. The plan listed above is very good.
