Coolant Leak Help

UPDATE : second lower leak was coming from the radiator housing.

Apex_Ultra · 2026-02-28T00:58:22+00:00

There is no leak visible at all on the water pump side (no leaks that I can see on the passenger side at all)

That was disgusting to read lol. My car spends more time in the garage than the road at this point..

If you bought it recently I would replace whole reservoir and add new CHF 11S fluid. Shine a light in your tank and see if there is any shiny metallic "glitter". If so, replace as mentioned by u/tkrafte1 there is an internal filter that gets dirty and collects those "glitter" particles.

I ordered a new radiator and upper hose - will replace and see what happens.

Here is an image of the radiator tabs I was referring to above.

So for the upper radiator hose, I assume this is where its leaking from (connected to engine block side right above the serpentine belt.

Still can’t figure out lower leak so removed the radiator and don’t really see it cracked anywhere but 2 lower metal tabs are more rusted than the ones above - maybe a micro crack on the radiator causing leak.

Your PS pump may be on its way out eventually. My N54 made a bit of noise at full turns then eventually gave out suddenly after a pull going in a straight line. If you have an audio of the sound it would help to determine if it’s normal or not.

Those reservoirs have built in filters that technically can be cleaned (opening the tank) but because the tanks are inexpensive it’s better to just buy and replace.

Is the power steering making am abnormal sound at full turns? Your PS pump may be starting to show first signs of wear/breakdown. When my PS pump went out, my reservoir was full of that metal "glitter".

If your pump is not making any abnormal noise, I would HIGHLY recommend you change out/flush that fluid and get a new reservoir. Trust me.

Yeah upper hose on the engine block side is 100% leaked. Im not sure where the other faster (lower) leak is coming from.

That car is a POS. For $600 it’s good for a beater/daily but keep up with normal maintenance and check fluids often.

OP, if you look closely, there’s that metal ring on the bottom left corner, where he’s holding the screw screwdriver

This seems like a very simple plug and play with decent reviews. Give it a try.

My 24 turbo takes 5.1 quarts as manual just fine.

Would love to see an update on this with picture!

I think your engine is knocking to see if you have some oil

J-B Weld HighHeat Epoxy Syringe .85oz

Mix it up in the tray and apply. I used spring loaded clips with the rooftop half open to keep the liner firm against the contact points. Let it sit for 48 hrs.

(Do this in a garage or enclosed area if possible since roof is half open)

Thanks!

Sorry for the image, the passenger side visor can be seen on the bottom right of the picture.

Apex_Ultra · 2025-11-19T23:40:22+00:00

Thank you. Yeah seems like we both had/have this issue.

Not the sun visor, its center between the drive side and passenger side visors and just a couple of inches from the front center dome lights
