Will A Mi16 Engine Fit In A 205 With Aircon?

[cRaig 265 1 Cars]

Hey there,

 

I have all the necessary bits to fit A/C to my 8v 205, but am thinking that in the long term a little more power would be ideal, so was obviously thinking of going down the Mi16 route. I know it would be easy enough to point out that I could give up with the A/C and save on a big powerloss.. but that would be boring

 

I was just wondering if anyone has any experience, or rough estimations as to whether there will be enough room in the bay for the compressor etc. Im guessing it will be very tight, but hopefully just possible. How is access to the crank pulley/ front of the sump where the compressor hangs?

How common was AC on the Mi16 engine? Because Im guessing having more parts to combine to make a working system can only be a good thing

 

 

Thanks

 

Craig

Easy in theory, Finding the parts is another one thou, Super Josh has it on his.

[cRaig 265 1 Cars]

Excellent

 

I have all the hard to find bits already (heater box, compressor, various pipes etc) And the sump from the 1.9 8v should fit the Mi16 I believe?

some interesting info in this thread http://www.aussiefrogs.com/forum/showthread.php?t=54945

Just leave the finned sump on the Mi engine, aids cooling too

You'll need a shortened inlet manifold too, to give clearance for the Rad and AC condensor.

HI

 

Yes it will fit with the A/C, i finish a project last week 205 CTI-MI16 ( The first and only in the country )

you will need shortened inlet (a bit more than usual ) and patient to play with the condensor pipes.

 

 

Best

[engine killer 5]

have been running my 205Mi16 with a/c for some years already. same compressor from Mi donor car, same a/c condenser as 8v205 (a/c model). the compressor is hanging around the bottom front of the mi engine (driver side) which is same as 8v, so the pipes/hoses will not be a very serious problem. but the inlet manifold is a serious problem. so i spent all my saving for tbs a fwe years ago because there will be a real pain in the arse to drive without a/c in hong kong.

Doing a seach seemed to lead back to you every time... is some q+a possible!?

 

How do compressors work? I have a couple lying around, but i'm guessing they will be no good after being exposed to air for extended periods of time?

 

Also, what is on the other side of the pipes coming out of the firewall? One of mine is bent - are they removable, or does whatever they are attached to need replacing? Parts are easy to find as every 205/405 here had aircon, but i've got no idea how it works...

 

Any pointers would be extremely helpful.

I've only done one conversion with A/C, despite every 205 and 405 in Oz having A/C. I used a shortened inlet manifold, but also had to rework the condensor pipes on the RH side of the radiator to clear the inlet manifold. If you're handy with an oxy torch it's no big deal. The compressor mounting points between an 8V and 16V are identical.

The compressor mounting points between an 8V and 16V are identical.

 

Which means you can use the origanal 8V hoses. Although the compressors are different, the 8V one only has five pistons, the 16V 7 pistons, which has the added advantage that it gives the system a bit more cooling capability and works really well in our UK climate. The other difference is that 8V system uses the twin-width crank pulley and 2 drive belts, one for the compressor and one for the alternator/PAS, whereas most 16Vs use a single belt to drive the compressor and alternator (PAS off the exhaust pulley). This means that the pulley offset on the 8V and 16V are different.

I think i will use a mi16 compressor then - is there any way of telling if they are ok, as mine has been of the car for ages.

 

I'm actually more worried about the mangled pipe on the bulkhead - did anyone know whether it can be changed easily? The condensor hasn't been out since i have had the car, so it should still be in there somewhere...

[Ryan 99]

The compressor might be OK. Check that the pulley spins freely. Then hook the plug up to 12v and earth and make sure the clutch engages. Slowly spin the clutch round a few times to make sure the bearings are ok and that it doesn't feel lumpy.

 

The pipes from the evaporator that come through the bulkhead are just short 90-deg pipes I think, so you can change them if you need to. Not sure if it's a dash out job or not (but probably is)

 

The condenser in front of the rad should be fine, as there's nothing to it really. When you get the a/c regassed it might be worth asking them to flush the system to make sure there's nothing wrong.

[Super Josh 4]

When you say a mangled pipe on the firewall, do you mean the aluminium one that runs across the inside of the engine bay? If so, then that just unscrews and is easy to replace.

 

As Ryan says, do the checks he has mentioned on the compressor. The only other thing that I would do is to remove the old oil from the compressor, should be a drain plug in the side of it. Then when you get it regassed, get them to flush the system with solvent to clear out all of the crap in there. Then they can pull a vacuum as normal refill with oil, ges etc.

It is the bit which that pipe comes from - it actually comes from the firewall. I'll try and get a photo of it...

 

Other bits should be easy to find here, as every 405/205 had aircon

[Super Josh 4]

If it is the bit marked in red (Which is part that the pipes screw in to), then you need to remove the heater box inside the car to change it. Which will entail the removal of the lower dash section.

It is 15 that is damaged. From that it looks replaceable though, which is good

 

I'm trying to find a compressor now. Will the mi16 one be worth tracking down over one from an 8 valve? I can't find the one i had...

That's handy Al, 5 minute job to change that

One the compressor front it depends on whether your Mi engine has the single or double belt set up. If it has the double belt you can use the 8V compressor, single belt will need the Mi compressor. You could change the crank pulley to the double width 8V one, but the Mi one has a harmonic balancer in it. For that reason I would keep with the Mi crank pulley, as Pug fitted it for a reason. I would have thought that it would be easy to find an Mi compressor in your neck of the woods.

Thanks for the help josh - it is greatly appreciated. I have a slight coolant leak, so i'll pull the radiator out soon and put a compressor in while it is out. Then i can at least run the pipes and see what needs work to fit...

 

The other thing i meant to ask you was about the seals, and where you get them from? Are they are pug part, or a standard thing?

[Super Josh 4]

The seals are a selection of various standard sizes. You can get them from Pug, but especially in your location, I would have thought that you could get a selection of seals for little money from a local AC place, online etc.

If you are planning on putting R134a gas in the system then you will need HNBR seals and the pressure switch that screws into the receiver/dryer will need swapping for a higher pressure one from something like a 306 etc. Don't forget to install a new reciever/dryer as that will be long gone after being exposed to the air for all this time.

I might worry about the seals later...

 

I've got some stuff anyway. I have a radiator thing (evaporator?), and a couple of the hoses and the wiring. I will get a new dryer - how much are they, and are they a pug part?

 

I suspect one of the long hoses has been bodged too - it has hose clamps holding it on. That doesn't seem right? It is actually much easier and cheaper than having them made like the standard ones, but this would actually be more convenient if they got damaged. I figure there is a reason they come with the fitted ends

[Ryan 99]

The radiator at the front is the condenser. The evaporator is the heater matrix thing hidden in the dash.

 

New driers are £39 from Peugeot. You can get one a bit cheaper from Autokool

 

You can repair the hoses with clamps, but it's a bodge. I don't really know what's suitable and what's not though.

[Super Josh 4]

I would just take the bodged up hoses to a local hose specialist and get them to make up some new ones. The connectors are all fairly standard and it will be a lot cheaper than Pug too.

This is what I need to do soon becasue I have just changed to a different type of variable displacement compressor off a newer Pug. So it will be interesting to see what.if any improvements that makes

 

On the receiver/dryer front I'm sure a local AC place in Oz will have something cheaper than Pug, again it seems to be a generic size.

I remember seeing one of the Guys on Aussiefrogs had a receiver/dryer that also had a high pressure side service port in it. If you can get one of those it makes filling the system a little easier than just using the lower pressure side one that is standard on the 205. I'll try and remeber who it was.

By the time you add in shipping and VAT Autokool comes out at £41.11

[gti_al 1]

Newer compressor? How are you making that fit? Considering they came on every car here, i am having so much trouble finding one that was known to work when removed. They have all either been dead for ages, or removed years ago and past it now

 

I'll take some pics of the hoses anyway. I printed off that diagram from earlier, and this is turning into an expensive and confusing jigsaw!
