Coolant advice and what to check
Hi guys need some help as I'm pulling my hair out now. A couple of months back my radiator was leaking with a visible crack at the top of the plastic on my bug wrx. Changed the rad kept the original hoses on as assumed these were fine. A few days later noticed I still had coolant leaking on the front splitter! So checked all hoses no signs of a leak but still Coolant leaking although coolant level didt really seem as though it was dropping. Now replaced all coolant hoses and guess what still leaking on the splitter at the front!!
When I had the rad replaced it was replaced with one that has a cap on the top when the original one didt so not sure if this could be a factor.
Any help or suggestions on what to check would be appreciated
Cheers

Did you t the overflow pipes when fitting? The blob rad with the cap has a second overflow outlet under the cap, add a piece of pipe from this into a t in the rubber pipe going into the overflow bottle.
Pm me if you need a pic of what I mean.

Hi mate yes bought the black pipe which runs under the air funnel then have it teed at into the overflow bottle. Checked all these pipes and nothing seems to be leaking from there. The coolant leaks on the splitter central and directly beneath the overflow bottle. The leak is defo coolant as I initially thought it could of been the aircon

The cap on the rad has failed. Get a cheap one from any auto supply store. Replace with iirc 1.1 bar cap. and retest.
Check the over flow of the coolant expansion tank. It should be wet on the open ended pipe. Check the header tank for water loss.
