I've been having trouble with my '73 2.0 running hot... while I was under it I realized that one of the heat exchangers doesn't have the heater hose attached, so it just allows air to escape. I temporarily plugged the hole and low and behold it now doesn't run as hot (210 after 30 minutes of 80mph highway) and it cools down quickly when I slow down.
moral of the story... check the stinkin' obvious... |

The fan moves air over the cylinders and oil cooler. The air assists the oil in cooling the engine and oil....
When a loose or disconnected heater hose allows air to escape the engine/oil temp goes up. Doesn't matter whether the heater is on or not. When connected the air is a closed circuit and works as designed. When a heater hose has a gross leak......the cooling air wants OUT....the effeciency of the air flow over the heads and oil cooler are disrupted. When the heater is ON and the hoses are connected with no leaks, the flow is still regulated and the cooler and cylinders get their fair share of cooling. Plus the ambient temp is lower assuming that you use the heat when it's actually cold out.... <_< |
