Hi people my series 2 rs turbo seems to be leaking water from somewhere. The problem is if you drive the car hard it i find a load of water on the gearbox and brake servo and metering head but the strange part is that i cant see the leak anywhere under the bonnet only seems to leak when car is driven hard and also if i leave the cap loose on the header tank its fine but i cant keep on driving the car with the cap loose. Heater matrix hose is dry and i have had the thermostat and gasket replaced and also the core plug. Its something on the passenger side any ideas thanks

hmmmmm, strange one, might need to run it up to temp and check any hoses for small leaks.

i checked everything today and can see water on top of the gearbox but no water leaking from anywhere is there a easier way to find out thanks

just got to keep your eyes open dude it could be a small split in one of the pipes going to thermostat housing, and are you sure its not coming from the thermostat housing the gasket may not have a good seal?

ASHCOSSIE

yeh like sufsrs said it could be the thermostate housing gasket i had that on mine or check the core plug that is just under dizzy

AKRS1

Had already done both things mate and its still doin it cant be head gasket can it

hey mate

sounds like one of those annoying ones. If ur saying it only seems to happen when the car is being driven hard, have you run it up to temperature, and then tried giving it some revs from under the bonnet?

there is other ways aswell. Pressure test the cooling system?

Or if you cant do that, you could try this as a lest resort although i dont like suggesting it, disconnect the fan switch plug, then run it up to temperature, and it will get that little bit hotter when the fan shgould of cut in, and try to boil at which point the pressure in the system will be higher and you are more likey to find the leak. Be careful though if you leave it too long it will boil over. It shouldnt cause any harm as such as you wont be leaving it to boil over for a long time, just be careful though?

let me know if you want anymore help mate

okay this a first looked under the bonnet and saw a few drips on the vacum pipe coming off the amal valve and it seems to be leaking from the fan switch sender unit can something that small cause this

you can get a flarecent liquid to go in the rad system, then all you use is a black light and look for the purple marks let by the now florecent leaking water. hope this helps

xr3iturbo

what an idea m8 top marks

AKRS1

now that the leak has got worse i actually found out where the water is spraying out from, the top of the coolant hose that runs from the thermostat housing any chance of finding out where i can just get one of the hoses without getting the whole kit thanks

AKRS1

anyone?

SafeChav

hello again mate

cracked it at last

have you got samco hoses on yours? Or are they just standard rubber jobbies?

AKRS1

hi i have the full set of samco hoses boost, coolant and auxillary hoses just one hose failed dont know how but thanks for your advice people managed to get the single samco hose from my local distributor without buying the whole kit.
