Replacing a Catalytic Converter - tips and advice

When you are intending to fit a new catalytic converter to a car, you should always remember to carry out a 4-gas analyser test and analyse the values before removing the old cat.

The 4-gas text must be recorded at 2500 RPM and the cat must have a temperature of over 350c.

The correct exhaust emission values are:

• CO < 0.2%
• CO > 13.5%
• HC > 15PPM
• ) < 0.2%
• Lambda 0.97 - 1.01
• Oil Temperature minimum of 90c

When replacing an old cat, it is essential to examine the complete exhaust system from the manifold to the tail pipe for damage, corrosion or leakage/blowing. Repair or replace as required.

Understanding DPF Regeneration - part 1

Did you know that:

- A new DPF will run for approximately 300-1000 miles before it first regenerates? But after then, it should happen around every 200 miles if the operating conditions require it, and the vehicle is functioning correctly.

- If a DPF is more than 80% blocked within 200 miles, there is almost certainly a problem with another part of the emissions system that caused the filter to originally block and no longer function correctly.

- A new DPF is not a flow through device like a catalytic converter. Exhaust gases pass into the filter and the gases must be able to flow through the internal cell walls in order to exit the filter. The DPF cell walls are porous to allow the gases through and are designed to trap any particulate matter (soot). This matter ends up deposited on the cell walls.

- If the vehicle is parked before regeneration has been completed and this process is repeated over a period of time, the soot deposits built up can reach a level where regeneration is no longer sufficient to clear the blocked filter. The resulting back pressure will cause poor vehicle performance or breakdown.

Tips for fitting a replacement EEC Catalytic Converter

As the experts in the aftermarket automotive industry, EEC is pleased to offer tips for the fitting of all our product range.


When mounting an EEC catalytic converter, please:


1) Do not use sealer or paste as this will invalidate your warranty and could potentially cause damage to the replacement catalytic converter 

2) Mount the new EEC catalytic converter, before undertaking final fixing check the converter has adequate space to move without touching the body.

3) Complete a 4 gas test immediately after fitting the EEC replacement cat to assist with location of any emission faults (the new cat will be operating at 100% efficiency at this stage).

 4) Perform a satisfactory road test

 Please note it is illegal to install a non approved catalytic converter on vehicles registered 1st March 2001 onwards.

Checks before fitting a new Diesel Particulate Filter

Before fitting a new Diesel Particulate Filter, you should check the following components on a vehicle:

* EGR valve or EGR pipe blockage
* Oxygen sensors
* DPF pressure pipes and valves
* Air flow meter
* Intake manifold
* Pressure switch
* Engine temperature sensor
* Engine oil - is it the correct specification for the engine?
* Intake manifold
* Turbo charger function
* Engine wear
* Fuel pressure
* Heater / Glow Plugs
* Leaking Injectors
* Blocked sensors
* ECU Malfunction
* Air filter condition

The above are just some general points, but it's recommended that a full service is carried out at the same time as installing a new DPF, and remember that most diesel engines fitted with a DPF require a specific low ash oil.

Some vehicles also require a special additive in the oil at the same time a DPF is replaced, and each vehicle will require an individual diagnostic investigation and testing procedure.
