Hi
I am new to doing the car maintenance. I am planning to replace the spark plugs, but am not able to find the required spark plug gap. I have a Fiat Tipo 1.6 i.e. L-reg (1994).

I have the Haynes manual for Tipo (inherited with the car), but this is only up to 1991 and the other manual I find difficult to get my hands on.

Could anyone help?
Thanks!
Larissa

I've just seen your message:

My Fiat handbook (Page 165 English version) says the gap should be 0.85 to 0.95 mm. This is not very helpful for us traditional Brits since most of our feeler gauges are in thousandths of an inch!

I will change my plugs soon, the manual says my 1.4 takes Champion RN9YCC, your 1.6 and other petrol models all take Champion RC7YCC.

The Haynes manual is now a bit confusing, see P85 Chapter 4 Ignition System.

For the 1.4 it says Champion RN9YCC/RN9YC, 0.7mm = 0.028 inch.
For the 1.6 it says Champion RN7YCC/RN7YC, 0.8mm = 0.032 inch.

So we are both confused!

Anyone got any ideas or useful links?

John

Lariosa,
If you´re buying new spark plugs forget about the gap, just buy the correct ones and fit them on. Maybe you could measure the new sparks as new for further checks.


Cheers

Lucho is right

1994 there was a few model of 1.6 engine
149C2.046 with 66kw and R-cat
159A3.046 with 57kw and R-cat
835C1.000 with 55kw and R-cat

but all spark plugs are the same :
Champion RN7YCC 0,8 gap
Beru 14R-6DU 0,8 gap
Autolite APP63 0,7 gap
NGK BPR7E gap 0,7 gap
Bosch FR6DC2 0,9 gap
