Catalysers - P.Mason {P}
We've just bought a Honda Civic, 1995, which is our first catalysed car. Am I correct in thinking that you shouldn't drive through water deep enough to make contact with the cat. as the thermal shock could crack the ceramic core? (I did try the search facility but couldn't find any details)
Any advice welcomed.
Many thanks,
P.

Main things to bear in mind about a cat (although I'm no expert these are just some basic points:

Obviously, never use LRP, just unleaded

Try to avoid driving through deep puddles etc where the cat is immersed/ heavily splashed

Try to avoid extremely short journeys repeatedly (unburnt substances passing through the cat is bad news), as engine doesn't warm up enough for cat to come into play properly.

Let's hope the previous owner(s) adhered to the above! Bear in mind also that most cats have had it by 10 years or before and need replacing to get through MOT.
