my engine 1275 mg metro engine is fine in motion if anything it reads a little cold but in traffic the temp gauge shows its too hot spark plugs are white indicating its getting hot. a new thermostat new water pump and a new better rad have done little to help a auxiliary fan on the radiator has helped but still getting above N on a hot day in traffic is it time to do a compression test cpuld it be the head? no sign of head gasket failure

incorrect timing can cause overheating as well, might want to check on that

 

just something I've read, others will have to fill you in on the specifics

If it doesn't actually boil, don't get desperate.  Try a different Temp Gauge, before moving to Inverness

What colour is the exhaust tail pipe ?

 

Lean engines run hot, up to a point, so it might be worth turning the mixture, richer, a 1/4 turn for a start.

 

There used to be a special Spark Plug with a quartz dome, called a "Colour-tune", that in dark conditions, revealed the richness of the exploding mixture.

Also check you have the correct pressure cap on rad. and also check it matches the rad neck depth. (88 degree thermostats and 15LB rad caps on A plus units).

Adding an expansion tank to the system can also help if not already fitted.

If it;s not going higher than 3/4 of the gauge, leave it, you'll tie your self in knots for no reason.
