Hi guys.
Need some expertise.
When I drive my 1200GX in town, even with lots of traffic light stops, the temp guage lies between cold line and the middle line.
When I drive at a constant speed of 120km/h on the highway it lies between middle line and the hot line on temp guage.
I did this test 2 times on the highway with different outside temperatures.
My radiator is a double core.
I took it to be cleaned up at a radiator shop.
And then did the second test with no better results.
My termostat was also tested 6 months ago.
It is the correct temp termostat and works fine.
Dodgeman suggested I put in a tripple core.
Thanks for the advice dodgeman.
I am just posting this to hear if somebody out there did'nt experience the same problem. If yes, what did you do to solve the problem?
I am thinking of doing the triple core change.

Something that I can also mention is that the plate underneath the engine has been removed.(I think it is the sump cover).
Must I put it back or will it not have any effect.I heard that someone told me it helps with the airflow.
Thanks
