Evening all.
Anyone got any thoughts on the following?
Car appears to overheat when driving at motorway speeds. It's started recently, the first symptoms were odd: it would climb the temp gauge after slowing down, all the way up to about 110 C, then would go back to normal.
For this I diagnosed a sticky thermostat, so swapped it out.
Now it runs hot ( right up into the red) on the gauge when going over 60. When stopped, it then will return to normal with the twin electric fans switched on.
It has a new water pump, new stat, heater works, there is flow from carb tower, and I'm running an expansion tank and filled it through the heater hose. The fuel gauge stays where it should be throughout.
It's started doing this since the rebuild on the front end, which involved a new pump etc. The water pump is a short nose type, originally destined for an mgbv8.
Current thoughts are to richen it up a bit, or take some advance off. It doesn't pink, and it doesn't overheat under idle conditions either. Could it be that the water pump is pushing it through the rad too fast at higher speeds?
Any other views most appreciated!
