5.0 coolant
The coolant seems to be foaming while the engine is running. The temperature never seems to come up. I haven't really looked into it much but what might be causing this. Runs good with the exception of running on the cold side. Sorry this is a 87 efi 5.0.

My first guess is that you have air trapped in the cooling system. You could try bleeding the air out to see if that helps. Take the cap off when the truck is cold, and start it and let it run with the heater on until the thermostat opens. Hope this helps
