I am the proud adopted father of a 90 780, a couple of days ago as i was passing a lesser automobile on the highway i felt a change and noticed that the car was nearly overheating, after pulling over i could see smoke coming from under the hood after a quick check of all roses and clamps i found my Heater control valve cracked in two, being pressed for time i replaced it with an HCV from the auto parts store down the street, the car holds coolant now but will slowly over heat over the course of a few minutes (i have yet to let it get into the red on the temp gauge) , whne i pull over and pop the hood the reservoir appears to be empty, but when I remove the coolant reservoir cap with the engine hot all the coolant bubbles up into the reservoir and when i restart the car after only a matter of a minute or two the temp levels out as i drive away then slowly begins to build again. I am a bit of a rookie here sorry for the long post any help would be greatly appreciated.
