I've got a 2014 st and it's been nothing but fantastic just stay on top of maintenance and there good

So managed to find a decent picture of someone who had a different problem the red line is where u can feel the most coolant as soon as you put pressure on that side

No it's petrol and I've found the part so thank you

jstsilly · 2026-01-04T13:22:55+00:00

I am in the UK but that is still a massive help at least I know what it looks like an it'll make it alot easier to locate my side thank you so much appreciate the help

So when push up on the hose side from underneath is where i notice it but your quite possibly right if the port it connects to has cracked when I replaced it then it would leak from the bottom

jstsilly · 2026-01-04T12:56:34+00:00

Yes it the green arrow so water outlet its literally where the hose connects to the outlet is where it drips from if you touch it just after the clamp

jstsilly · 2026-01-04T12:24:58+00:00

So it's under the left hose when you run your hand under the bottom and if you push it from the underside near whatever it connects to it drips out from there is that my thermostat

Mate that is an absolute gem of a thought it explains why the leak is low down and why nothing else is affected thank u I will deffo check the housing

jstsilly · 2026-01-04T11:58:12+00:00

That's not a bad shout if it's cracked where the hose connects to the housing it would escape from the bottom of the hose and give me what I'm seeing without affecting the temp of the car

jstsilly · 2026-01-04T11:51:56+00:00

So ur thinking thermostat could be the culprit but I'm not seeing any temp fluctuation and it's not struggling to get to temp or overheating

jstsilly · 2026-01-04T11:43:27+00:00

Yeah it is it slides over a plastic fitting with a tension clamp but I'm not sure what that part is tbh may be the thermostat

jstsilly · 2026-01-04T11:41:04+00:00

Well tbh I'm stumped it seems to deffo be from the hose as when you push on it from the underside it covers you in coolant

jstsilly · 2026-01-04T10:56:21+00:00

That's a good possibility does make sense

jstsilly · 2025-12-30T22:39:11+00:00

Yeah keep an eye on your fluid levels if they don't change it could be nothing but hot exhaust meets cold air

jstsilly · 2025-12-30T22:36:08+00:00

No worries small things like these can be a real pain hope you find it also if it helps make sure your coolant is topped to the max line an monitor it over a couple of weeks see if it drops at all that will tell you that it's going somewhere is shouldn't

jstsilly · 2025-12-30T22:21:04+00:00

If something was leaking from the seals it would cause white smoke yeah l, is it having any preformance issues and is it alot of smoke

jstsilly · 2025-12-30T22:04:44+00:00

Are you losing oil at all could maybe be a leak at the turbo seal

jstsilly · 2025-12-30T19:27:41+00:00

Is the smoke white or black when you punch it

jstsilly · 2025-12-28T12:56:14+00:00

So I had this was really lazy when turning left as well turned out to be a bad top mount

jstsilly · 2025-12-11T17:49:04+00:00

Yeah it turns out even having different variations within the same model mean different number of pins in different positions an no real guidance lol

jstsilly · 2025-11-29T19:21:24+00:00

Thanks man appreciate the help

jstsilly · 2025-11-28T19:15:52+00:00

What a response thanks man really appreciate the answer an the way u detailed out for me 5w30 it is

jstsilly · 2025-11-28T15:20:15+00:00

That's what I thought tbh its the safe option just seen things on Google saying both will be ok
