recently a mate of mine drove across a ring road and it went straight into the red!

just wanderin wat sort of things to check for?

:thermostat
:blockage

is as far as we got,

also he says to me his heaters in the car only blow hot air out, i was reading another post and it said that this could have something to do with it some how?

any ideas on wat else to check while im there would be great!
