Real quick, sorry I am out the door. This morning I started the car and the hot water sign on the dash litup. This has been happening lately according to my wife. (thank God I changed the multi-function switch recently to see the car was not overheating) Anyway there were no codes stored (4444). Any ideas?,BTDT? Thanks as always Dan Hamren 1987 5000 csqw 145k 1.6 bar 1.8 after new IC hose
