Hi all,

I've a 1.8 FR with the Gen3 EA888.

Sometimes when I pull up I can see steam (not loads) from the bonnet. Coolant is dropping but only very slowly.

Changing the oil today, I thought I'd hunt around to see if I could identify the location. I know that the waterpump is a likely culprit but I'm not going to just spend £300+ and take a days leave to change it only for it to turn out to be something else!


Strangely, I've noticed damp on TOP of the I let manifold. Maybe unrelated.

Some other possible areas....

This one, a coolant coloured drip of the injector rail, how would it get there?

Some residue on the oil pan..white...could that be coolant or is it road salt maybe? I don't think it's this one. But never seen white residue on an oil pan before, then again all my other cars have always had a smooth metal pan.

Could it be this coolant connection near the turbo, which I see from Google is common. It's such a hot area...no moisture there, but there is some crusty residue (but it's not G13 coloured!).

Underside of the waterpump looks OK to me? It's on 80k, I believe. 2018 car.

This coolant hose looks like a possibility? Maybe I could switch out that clamp for a stainless jubilee clip?

Last thing - my header tank was still the original 'mit silika', so I changed it for a brand new one (and new cap), without. Will see if it's still doing it later today, would be nice if the new tank/cap resolved it but I think it's unlikely.

Cheers in advance for anyone's help.
 
For the sake of future-proofing your vehicle, you'd be better off replacing the thermostat unit and water pump.

Both well know to leak on the EA.888

I recommend replacing the coolant nipple with a billet version. Its not that hard and a good futureproof mod. I bought mine from Aliexpress, fitment is 100%

Have already ordered one to fit at the weekend (I went for an OEM replacement tho - £16 delivered).....

Thanks, I'll be happy/lucky if it turns sour to be that and not the pump.

I realise that the pump will probably fail one day (if it hasn't already) but I'm busy dad with school age kids working full time with a dog and aging parents etc etc so I'll only take the time to do that if I really have too.

I do remember tho doing loads of preventative maintenance on my R5GTT back in the day. Replaced half of that car that didn't need replacing lol :-D

All the above said, I am still half expecting my leak to turn out to be the waterpump just from a spot I can't see. Still can't understand how a red coolant-like stain could appear right up above my injectors. Only just bought this car so it's history I do not know.
 
@barki Im also into preventative maintenance :cheeky:

My 2015 still has its original waterpumps (the electric ones), with around 140k kilometers, so you should be fine :)

There is airflow over the engine if you have the air snorkel opened on one side (the default config), that might also come into play with your leak (?). You can close it up for a little more air towards the air filter, see my build thread for more info. Also known as the "Pikey R600" mod


This one is also worth it
