Your car is from the year 2000 so I'm expecting you to have the original type in the radiator return flow. In this case, try removing the hose on the cooler outlet side. The contents of the radiator will then flow through the cooler so, if it has broken down, I would expect to see engine oil drawn out with it.
However, if your mayonnaise is limited to underneath the oil filler cap, which seems to be the case from what you've said, then follow the advice initially given by Trikey, i.e. use the car more and make sure the engine gets hot for more than two minutes!

Hi, Simon, I think I have a big problem.
I cleaned all the mayo off the cap, and this morning I drove with the vehicle.
The cap was full of mayo and the coolant level went down.
I think the coolant goes into the engine oil.
Where is the oil cooler located?
