I'm stumped and I'd like to draw on the experiences of folks here.
My MGB-GT is running hot and I have had no luck finding out why. It runs great (engine rebuilt within the last 5K miles), but it heats up fast (reaching 180 degrees within a mile of home), and the temp continues to creep up. I've never allowed it to overheat but its come close. Here's what I've tried so far;
* removed and flushed the radiator, no crud in coolant or radiator
* checked timing (static, mechanical and vaccuum advance):OK
* checked hoses for collapsing or blocks
* has good compression, no water in oil or bubbles in radiator (head gasket is OK)
Today I replaced the original 180 degree thermostat (its OK) with a 160, and it has the same problem. Just takes a little longer for the temp to rise.
