Pe rform a visual checking of the catalyst condition. O deforma tion may be the explanation for its
non-operation.
Ch eck if the catalyst has not previously suffered therma l shocks.
If cold wate r is getting on a warm catalyst it may cause its damaging.
Ch eck for oil or cooling fluid excessive consumption Ask the client if he has used an additive or a
sim ilar product. This type of product may inhibit the catalyst and render it inefficient on short or
l ong term.
Ch eck if there was any combustion misfires. These may damage the catalyst.
Ch eck during a drive test for any noises during running.
If the damaging cause has been found, you may replace the catalyst. If you replace the catalyst
without det ecting the cause, the new catalyst may be damaged al so very qui ckly.
