Small Coolant Leak

Hello.

Today I had a very smaal coolant leak somewhere beside the radiator cap.
Do I need a hose clamp on the hose that goes to the recovery tak?
What else could that be?
I took a pic, but itīs only a mobile phone pic.

Thanks for your help.

You are sure it's not your radiator cap Nico? Or the hose might have a split in it.

Today I cleaned the hose and while the engine became hot there was no more coolant leak.
Could the cap be damaged after only 3.5 years?

Could be the radiator cap. But most common issue and is VERY common is the radiator itself. Where the top plastic is crimped to the aluminum core. The difference in the materials and the temp going up and down. They expand and contract at different temps.

a only 3.5 years old radiator could have a leak?

But go with the simple things first....

Get a new radiator cap.

New hose to the overflow bottle.

Cheap items.

That would be a problem. Jeep spare parts are very expensive over here.
But I donīt thik itīs the radiator. There was coolant on the plastic next to the cap and the hose was wet where it is connected to the radiator.

BTW. I forgot to say that I removed the recovery tank and the hose one day before I noticed the leak. Perhaps the hose wasnīt connected tight enough after that.

Iīll take a look at it tomorrow when Iīm back in my garage.

Good chance it may just be the overflow hose then.
