MarkVIII radiators do not have a cap. Park car on ramps or hill (raising front end) to ensure complete "bleed" I know it as "burping". Some have engine off, I prefer it on allowing me to rev up to 2,000 after I fill the system to burp it. Remove the engine coolant tube fill plug on the engine (on U joint right in front center, looks to be flush but there is a little lip there, DON'T STRIP IT, if it has never been opened use some PB Blaster or release spray) and remove the reservoir cap, Fill at the tube fill plug until res. Fills up, put cap on reservoir and continue to fill at the tube fill plug slowly. Do normal a/c heat test while monitoring the temp.
