Default Coolant leak

Hello,

I would like some assistance maybe someone would have an issue with the same type of coolant leak, I cannot seem to understand where it's leaking from, I got the idea that it's leaking from that tiny hole, but from where is that tiny hole? Is it from a radiator?


Thanks

Beg, borrow or steal a cooling system pressure tester. This is the doohickey that looks like a bicycle tire pump and connects in place of the reservoir cap. You manually pump up the cooling system to the rating on the cap. If there are any external leaks in the cooling system, you will be able to find them.

The big advantage of the pressure tester is you put the system under much more pressure than merely running at idle. Many leaks will not be apparent at the reduced system pressure present at idle. With the engine cool and switched off, you can poke around with no risk of burns nor danger from moving parts.

If you'd rather not spend the money to purchase a tester, some auto parts stores have free loaners.

Ok, so I went to the mechanic and we removed the engine undertray, from the looks of it the radiator that is leaking is the one marked with blue, can anyone tell me from A to Z which radiator is which? Tried finding a schematical sheet but to no luck.

Attached is a photo from an Ebay listing.

Also the leak has gotten far worse.

Go to Ebay and please get a manual for your car!
The discs are cheap and will be very useful.
