Hi forum

lots of posting recently, finally i need to remove my Turbo. anyone have a guide or any advice?

2001 Punto JTD turbo diesel...

It is throwing Oil intothe engine so has to be replaced

any help would be very much appreciated

Turbos are simple things just unbolt it and bolt on the new one with all new gaskets. BUT make everything is really CLEAN. The smallest bit of debris hitting the spinning turbo will damage it. The rotors go at something like 100,000 rpm.
If the bolts shear off drill them out and fit new socket caps and nuts. Stainless bolts and carbon steel nuts or carbon steel bolts and brass nuts. Lots of coppa slip. Dont use stainless/stainless.

You might need to adjust the wastegate actuator but only if you find the turbo is over-boosting. Worry about that id you get a power flat spot just as you put your foot down at sub 2000 revs.

Hi there,

thank you for the reply. I have managed to disconnect all of the hoses, but i can not work out how to remove the turbo from the exhaust manifold. To help me get a view of how this works, do ALL exhaust gases pass through the turbo, and then exit through the exhaust?

i cannot work out how to disconnect the turbo from the manifold... it looks like that is the last think i need to do before the turbo will come off....

i unbolted the exhaust pipe from the down-pipe, but i can not get to any other bolt...

any advice? i can not find my haynes manual anywhere!!!! anyone got a schematic blow up showing what has to be unbolted to let the turbo release?

ok, i think i am going to have to give up... this Punto is killing me,and i have loved it for so long. to get the turbo off, i cannot see what to unbolt... there apears to be a solver collow, like a strong jubilee clip holding the turbo to the main manifold... i cannot see any other bolt holding the turbo in place

to get to the screw holding that silver band on, looks like i have to take the entire exhaust manifold off the front of the engine, as the solver cover on the exhaust will not budge as the coolant pipes are in front of it...

basically, to get to one thing, u remove another which u need to remove another... who designed this layout!! argghhh

anyone have a step by step guide?

is there a hynes manual for the diesel punto? i can find one for the old punto, but the new one is petrol only, which is rediculous, so my hands are tied!!

I feel your pain... the engines are assembled and then put into the car, so logic dictates the easiest, less hassle way is to take the engine out.

On the +ve side:-
Easy access to anything & everything & can all be done at once, less scraped hands, better end result.

On the -ve side:-
More work, more expense, more time.

Go on... whip the lump out!

Looks like a random Spam Post to me.

don't suppose you know what i have to do to get this turbo out? i would love to know the high-level basics, i.e. you need take off the exhaust, drain the cooling system, remove radiator etc....

i am just thinking that i am missing something simple, and it will just come off... i can not afford to pay a mechanic but i am fast approaching the thought that i have no choice....

Sorry no I dont, I'd take the engine out personally and treat it to a good overhaul, makes turbo access a cinch too...

I recently did the valves on an HGT Punto. The head had to come off complete with the whole inlet manifold, injection gear etc. and the exhaust manifold also had to come off the car. Access is tight.

Knowing how tight they are for space I would bet the only option is to take off the exhaust manifold back to the cat. As for that clip its probably a fit once and rip it off type like they use on the coolant pipes. Cut it and later use a good quality jubillee clip.

Keep at it. The darkest hour is the one just before dawn.

thanks for the words of encouragement.

I think you are right, if i can get the exhaust manifold off, i will be in good shape... problem is, i cannot work out what to take even it off doh!.. there is a heat-shield in front of the manifold, that seems to big to be there, but there it is.. looks like i have to disconnect some of the water hoses, but i can not work out how them fiat hose clips work... i think i will go with your idea, and cut them and replace with jubilees...

If I disconnect the hoses, I will loose coolant… when I reconnect them do I have to do anything to ensure I do not get a air-lock?

OK, i am getting there, i got the cooling system off (the main cooling manifold at the top of the engine). I managed to get to all the bolts that hold the exhaust manifold to the engine.

The whole manifold and turbo assembly is loose now, except it is being help on to a metal pipe that i cannot work out what it is, and i can not get the bolts off.. i have taken photos so i am hoping you can help.

first photo shows the pipe, and the Allen-key bolts that will not budge (OK, i got one to budge, but the one underneath that you can not see seems to be sheared off)

the 2nd photo shows the other screws that seem to connect the top section of the exhaust manifold to the turbo assembly... i can get to the front 2 nuts, but there are 2 on the back that you cannot get to without a small spanner...

so, i am looking for ideas...

1. cut the metal pipe and get it welded once i get the turbo back.
2. work out how to get the four nuts off, 2 of which are near impossible to get to

please help.....

persistence is definitely the answer on Fiats... but i am definitely more confident to do more work now...

I believe that taking the radiator out, would help.

thanks Kole... i was thinking the same thing.... i wonder is there a guide to doing that.. i already have all the hoses off, so there is nothing to worry about there, it is just getting the damn thing out... it doers not seem that well bolted in, so maybe it is not as hard as it might be... I have not taken a radiator out of a car since the mid 80's and it was hell back then...

any advice?

assuming it is:

1. disconnect wiring loom from fan.
2. undo some bolts somewhere
3. lift out

simple as that?

Never did it on JTD, but if you don't have A/C, that should be the right way.

OK, i got the turbo off... 3 days but it is off.... had to loosen the radiator, then take out the radiator fan. problem was that the Allen key bolts I photographed on the previous post were sheared off, which means i could not get the whole assembly out no matter how much stuff from under the bonnet i removed.

what i had to do was use a hack saw to cut through the metal pipe that6 goes from the turbo assembly to the back of the engine (assume it heads towards the EGR?)

so, once i get the new turbo i am going to have to get a welder in unless anyone has an idea...

so come on everyone, give some ideas, what passes through this pipe? i assume it is Hot exhaust gasses under high pressure, as it is a metal pipe....

thank you all for help so far...

I would say file the ends and joint it with some silicone tube and jubillee clips. That stuff stands 250 degs C so should be fine.

Some people disconnect the EGR and get better MPG. Its supposed to reduce the particle emissions, but most diesels only smoke at high revs and EGRs clog up the inlet ports so I'm not conviced about EGRs,

good, thank you for the reply. I can see the last time the turbo was replaced, the mechanic musty have sheared the Allen key nut. i think he cut the pope and then welded it back in place, as that is where i cut it (though the weld). i would much rather use a silicon pipe...

will just wait for the turbo to some back now and see how i get on....

If its the EGR you could cap it off and see if it makes any difference. Make sure the air filter is clean and get a pal to follow you while accelerating. If its smokey put the EGR back.

Be VERY careful when you rebuild. ANY dirt in the turbo pipes can mash the rotors. You really cant be too careful on that score.

Always use a good quality anti sieze paste. Go to a decent nuts and bolts factors. Dont bother with cheapo copper tinted grease sold in Halfrauds et al.
