Gidday guys,

I have just changed the plugs in my S1 and she is running really well. However, I note that she is now running at the top of the "N" range on the temperature guage. The truck never actually gets into the "red" H zone, but should I be concerend... for the life of me, I can't recall if the temp was high before I removed the fouled old plugs....

What do you all think?

well which engine spec do you have? There are two:
Detoxed and non-detoxed. The detoxed engine has
the hotter thermostat which is 88 degrees C. the non-
detoxed engines have the 82 degrees C stat. so I would
check engine numbers to be sure!!

my ex army one runs on the middle of the N or if im dealing to it or going up a long steep hill, which there are planty of on the east coast here, it moves up a little but never moves off the top of the N. I have found that these do cool pretty well, keep an eye on your radiator levels, and the water tank that over flow thingy. Maybe the radiator could be clogged inside, needs new coollant, or what i did to mine is gave it a good water blast from the front (be carefull not to get too close or you might beend the fins over)

There are many things to consider, also is your engine taking in enough cool air, as the standard air box intake is up behind the carbs where it sucks in already warm air.

best of luck

The engine could be running lean? Although it is strange that this would occur after a plug change. Unless you had some real shot ones before that had the engine running on 4.5 cylinders

Also, I have had plenty of troubles with the temperature senders, so it could be one thing to look at.

Hi guys,

The engine is the standard Rover V8 that came with the truck from the NZ Army. Engine Number is 10G09778 CR 8.13.1. I have fitted new NGK spark plugs which are NGK BP6ES type. Could these be causing it to run hot? The truck is runs a 24V electrical system ex NZ Army with a Mallory Army 589 retrofitted distributor.

Its not that it runs hot into the actual "red zone" more that it just hovers at the top of the N zone. The oil temperature always stays in the centre of the N.

Any further thoughts guys? Do I have the correct plugs fitted? Does having a 24V ignition system mean I have incorrect plugs that are menat fro a 12V system fitted?
