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?

At the front lower edge of the engine on the right hand side (when viewed from the driving seat) immediately in front of the oil filter.

Also what colour is the exhaust smoke? If it's not white then that's likely an indication that it's something other than a HG.

Hello, i have no smoke from the exhaust, only a little bit the morning when it's cold.

Hello, the coolant coming out of the oil cooler is the right color.
On the other hand, I have changed engine oil,and the oil has a chocolate colour. The previous oil change is only a month old.
I’m really starting to worry.

What quantity did you drain compared with the amount used for the oil change a month ago?

Do the Crackle Test as I described earlier and you'll be 100% sure if water's present.
Oil cooler cross-leakage is usually 'tested' by simply bypassing the coolant flow using rubber hose and suitable clips. If coolant loss stops, you again have 100% answer.

Thank you , i will try this.
Can i use rubber hose with the two coolant hose from the oil cooler for create the bypass?

I drove an hour with new oil and new coolant. The cap already has a lot of mayo.
I will do the crackle test tomorrow.
I think the coolant goes into the engine oil.
I am so disgusted.
This car keeps giving me trouble.
