well guys my mate has a s1 with a watercooled s2 turbo fitted ,

when the car is driving the temp stays fine ,but when he stops the car starts gurgling like mad .

today it was decided to bypass the watercooling part of the turbo and see what happened and the gurguling stopped.

the car seems to have some s2 hosing and some s1 ,and we arent sure if its all plumbed up right .

first of all ,is it possible to run the turbo without the watercooling and blank off the housing and go back to standard hoses etc ?

or

could the watercooling housing within the turbo have a crack in it that is filling the cooling system with air thus causing the problem .

he is pulling his hair out at this stage ,so any info/help would be much appreciated

When I had my S2 I ran mine without the water pipes to the turbo never had any problems and ran it with 24 psi for 4 years.

Same deal with my fiesta james, and it turned out to be a cracked head!!

And my fiesta was running the T3 without water feeds

Bit of a debate about water cooling, while the T3 fitted generally can be ok without, its best to keep it if you can.

See here for why

The gurgling sound is most likely the turbo boiling the water inside the core which draws cooler water into the bottom. This takes the heat away from the core. It also heats up the cooling system quicker and helps keep a bit of heat out of the oil system.

make sure your water system is under pressure else it will boil too! Maybe this is part of your problem

cheers aston for the info.

i dont think it will be a problem with brian as he drives like a girl

is this standard for s2,s to gurgle like this ,mine never did back 20 year ago

I must give Brian a shout on facebook!!

But if he has had the head skimmed etc, then i would seriously look into taking the thermostat out and also have a look at the heater matrix!!

I also changed the heater matrix in my fiesta and it made a dramatic difference, but was still pressurising a little bit. Then one day i threw the head up, ripped off the head and seen a rotted part of the headgasket and in a deeper inspection of the head, it had a hairline crack on the face where the gasket rotted. Swapped the head over and it was grand after that

lockie

if its fine with no water feeds then yes remove them. ive had loads of rs's with them removed & cossies.

another thing if it does come back is the header tank cap.
had loads of issues with my series 1 in the past boiling up in tank etc & it turned out the headertank cap was knackerd lol. i wouldnt have gueesed it myself but it was an old skool ford mechanic at my local dealership that spotted fault

As long as you drive your waterpump has a higher flow, so less change on boiling. There is a change that this is part of your problem. If you know your pressure you can also calculate which temperatures you are reaching with boiling water. Might be interesting to see how bad is it

head was inspected john and was fine ,and he also ran without thermosat and done the same thing .heater matrix might well be worth a shout but his heaters are fine from what i know


cheers lockie ,he is leaning towards bypassing the water feed to the turbo.

i did mention the headercap and he said its fine

it might be worth putting a bit of tape on the threads just to check though

lockie

turbo water pipes are normally connected: top turbo water pipe is teed into the top rad/thermostate houseing hose & the lower turbo one goes back to the side of the radiator.

but once again ive rad many cars at high boosts with no water feeds with no issues.

keep us posted on the updates

thats exactly how is was connected lockie ,but once he bypassed the turbo the gurgle stopped

That is an odd one, cause its meant to be there, mine did it a couple times months ago but hasn't since I put my new engine in. Same turbo setup etc.

I'd rather have the water in the turbo, because why not?

Cameron

If i remove the water pipes from the turbo do i need to blank the holes for the banjo bolts on the turbo or just leave them? my engine runs far far too hot

chink

sorry to bring up an old thread mines doing the same and its bubberling on water pipe to thermostat how can i run the turbo without water to see if this is my issue

mentalasanything

Just remove it and block it off.

Just FYI, I had the same problems as above. I have an Airtec rad and FMIC, 82 degree stat and S1 fan switch.

To cure the problem I replaced the header tank cap. Problem solved! Lots of people have had this issue with S2's, most just live with it.
