Losing Coolant.. Please Help :(

[St-3 Wr330]

Hi guys.

Can somone help me please?

I have a 06 wr330.. fully modified.

I am losing coolant by the litre load.. approx 1.5 litres every trip.

There are no visable signs of leaks anywhere.. completly bone dry.

I can fill the header tank up to max and leave the car running for a good half an hour with no water loss but go 20 mins down the road and it will nearly be empty. There is no overheating unless i really drive it hard but the needle will only rise for a couple of seconds then drop to normal.

It seems to be boosting ok except for 2nd.. but because of the exhaust system the management light comes on with a faulty lambda sensor so im wondering if its entered a safe mode?

I have read about cracked liners..cracked turbos.. hoses.. faulty rad units etc. I really dont know where to start as there are so many options.

Can anyone point me in the right direction.. if they could i would be eternely grateful.

Thanks guys :)

My brother had this problem before and it turned out his water pump was faulty. He was the same couldnt see any water leakin from anywhere but it was going through water like a fish. Hope this helps

His isnt an st but still should be relevant

Hi dan.

Thank you for the advice :) i hope it is the water pump.. it will be the cheaper and easier fix compared to gasket or turbo.

Do you know if he had any loss in power?

Thanks again

Just an update..

Took the car to the garage.. cracked head gasket or liner!!

Took it back to the garage i purchased the car from.. he spoke to a specialist and its more likely to be the liner which means a rebuild or new engine.. luckily i got a warrenty for the car and everything will be paid for.

Its a pain in the butt as im supposed to be on a stand at trax next week..

Dan.. thank you for your input. Was very much appreciated.

No problem mate thank God you dont need to pay for that! Lol warrantys are great when they come good for something like that. I paid £500 for my warranty and its saved me over £1200

Thought it might have been the head gasket or something like that - the coolant finds its way into the combustion chamber and turns to steam - thats why the coolant goes down and you don't see a leak

Thank "goodness" it will be fixed under warrantee

[St-3 Wr330]

Yeah thank god it is going to be paid for.. normally they aren't worth the paper they are written on.

Never mind its happened now and there isnt alot i can do about it except wait for it to be fixed.

Thank you for your input peeps :)

I like warranty direct, as after a period of 90 days, they also cover wear and tear for items, as well as mechanical failure. I have a policy on this car, and it costs £20 a month, could be a waste of money, but given that when I was looking at getting a CMAX, cars around the 90k mark all had a brand new gearbox a year or more ago, so even if I waste £200 in the first year, it could save me thousands after that!

I used a company called "autoguard" everrhhing sounded great.. untill i needed to use them.. in the small print was a limit. I could use it as many times as i liked up to the value of the car but.. a £500 limit!! That would have been great untill my car bill was just over £2000. Still.. £500 is £500.

If it's a cracked liner I think a new engine may be the better option, try and source an RS engine as they don't suffer from cracked liners.

If your fitting another ST engine get a specialist to do a block mod on it.

Loads of info on STOC http://www.focusstoc.com/forums/

Unfortunatly it will be another st engine going in.. lee from devil devolpments is in line to do the work hopefully and is in talks with the the guy who is paying for the repair about doing the block mod. As im not paying for the new engine it might be a tall ask to spend double the money on an rs engine as i have already put this to devil devolpments.

Ill do a bit of hunting around tho and see what i can come up with
