Aircon compressor.....

thearrow · 08-12-2014, 02:57 PM

Has anyone had to replace their aircon compressor on their Cougar???

I am having trouble finding a replacement.

Does anyone know the correct part no. for a 2000 model??

As usual my investigation have shown that Ford used a variety of different manufacturers over the life of Cougars.

Sorry to hear about your aircon.

I have been through all this and I can tell its not easy to find a replacement.

Best and easy option is wreckers. I can give you part number in Jan. I have a spare a/c compressor that I bought for $450 or $500 from wreckers few years back. The thread housing for that bolt from a/c hoses that bolts on to the compressor is cracked I think.

I kept it as spare in Melbourne at my sister's place. I am going to Melbourne on Jan 1st and then I can give you exact part number.

Meanwhile this might help.

If you see any compressor that has different hose location then its wrong one. The one listed in the link definitely fits our Cougars.

What happened to your compressor anyway? Reason am asking is, mine was leaking gas which later I found that its from a fine crack at the hose joint and not the compressor. Few couple of a/c repairers couldn't spot this. Even die test, pressure test couldn't didn't help. Just a wiggle did the magic though.

Finding the hose was another epic that eventually ended sourcing from Wreckers.

Cheers

Approach an auto electrician who deals with A/C stuff, or check out Ashdowns as they're a A/C component distributor.

Also any workshop which does A/C should be able to make up new A/C hoses if you have any issues.

Spoke to my auto electrician yesterday and he is going to drop the unit down and see if he can get the part no. off it his advice is that it is just not pressuring the system. According to Ford it is XS7H19497AC however I would be more comfortable knowing it exactly.

I am reluctant to buy one from a wrecker because the unit will be at least 14 years old and you only get a 3 month warranty anyway.

The units are available in the UK as they were the same units used on the old Mondeo's in the UK and there were 1000's of them sold during their production run so there are plenty of new OEM ones around.

I purchased an mondeo scroll compressor from UK. when I was chasing a clutch asm for a FORD HALLA compressor verion.

the scoll pump with low temperature pressure temperature control valve It was to suit the mondeo and MG engine.

the ports on the front- I kept it as I had planed to use it on the last AU--but it never died before the car did.

compressor cost a few pounds to buy from a clearance sale and 60 GBP for DHL. It wa confiscated by customs for a short time as it was prohibited import with out a lience. that I had.

thearrow · 11-12-2014, 01:45 PM

Dave if it's not to much trouble and you still have it.....what is the part no.?

Davehoos · 11-12-2014, 07:43 PM

has ford ports on the side not on top.
manifold type with alinement stud.

Ford scroll yellow label-sanden style type pump with control valve.

2002sept03
V64N-190629-AB
1198
P2

under lined number could be a letter as its smudged.
1198 will be the sanden number,

has Focus as well written on tag.

thearrow · 12-12-2014, 10:05 AM

A pity it is not the right one as the Cougar compressor has the ports on the top.

Davehoos · 12-12-2014, 04:34 PM

Have worked on a few. the hassle wasn't getting the a/c to work but getting a clutch bearing and pulley to line up with the belt. The compressor was available at the time but the owners didn't want to pay.

Halla or Visteon compressor you can use the casing and fit in a cheap internals as long as the bearing hasn't destroyed the compressor nose. the sanden [ford scroll] you can swap the internals into the original housing but clearances are critical.

the photo has part number on it. new part.
similar advertised for double price jag X type and MG.

A while back the place in Wollongong had sourced these out correctly and landed 6 brand new out of Taiwan (not china).. who directly or indirectly were the supplier or aftermarket supplier of them for the EU & UK market. Apparently the cost was up around A$600 and for that they made around $50 after import and taxes..but they did find the 100% correct units.., then as people also wanted endless warranties nationwide... but in fitting them would cut corners and not replace filters/ switches... it was not viable to warrant or maintain more inbound. You get no warranty realistically on a ebay sale out of the UK on something like this after what.. 4 weeks after it would arrive if your lucky.... Ford once had them for around $2300 if I recall....more then many of the cars are now worth.

Davehoos · 26-12-2014, 04:53 PM

A supplier for my last employer sourced components from singapore/malaysia and often tiawan via singapore. then supply factory parts supply chain-so they could claim local content. Most of these gents have retired ans sold out to multinationals following the last government logics.

often they dump 20 liter buckets of seconds for us that had been incorectly supplied-metric treads-or silly stuff like semi assembled for a production line.

depending of what the cause of a visteon compressor failure you need to do a full rebuild of the system as they a fragile. the scroll pump spins at high speed and is known for oil starvation-hence the control equalisation valve in the rear on the expencive versions.

most of the replacments I have done are due to wet weather and pulley/clutch coil failures. the bearing destroys the alloy nose.

thearrow · 27-12-2014, 10:41 PM

I think I am on the right track now. As these units were used in Jaguars, Mondeos and Mazda's then you would think were plenty of them around. In the UK they were used on Mondeos and X-type Jags and there 1000"s of them sold in Europe so you would have to think they were available.

It seems to me that when Ford USA sent the Cougars to Europe to be Europeanised Ford Eorope changed the fuel pumps (cos the yanks were already having problems) and the aircon compressors (probably for the same reason).

Anyway I am not worried about warranty because it's a bit hard to claim it from a company in the UK that is just a risk I have to take.

Received my new compressor on Friday and will get it fitted this week as I am also in the process of getting my timing chain cover gasket repaired a common fault on the Duratec 2.5 motors.

Apparently this is a huge job.

REDDYZ · 12-01-2015, 05:37 PM

You might want to get rocker cover gaskets replaced as well. I changed timing cover gaskets on mine and personally I recommend to have sump gasket handy. Because timing cover sits on sump and when you take timing cover off it peels off rubber seals from sump gasket. You will then have to use silicone to seal it.

REDDYZ · 12-01-2015, 05:42 PM

UIM, rocker covers, mount, power steering pump, mount bracket and many more bits and pieces has to come off. (Maybe LIM as well, don't remember).

thearrow · 13-01-2015, 11:03 AM

Yes I think I got everything from Rockauto a while ago but my mechanic will get what ever I have missed. Just hope it all goes back together OK.

I am also replacing the chain guides.

I recently replaced the throttle position sensor and jeez it has made a big difference much better economy and throttle response.

thearrow · 20-01-2015, 10:14 AM

Back on the road after a major overhaul, new aircon compressor went straight on (which was a relief ).....however new water pump, new power steering pump new engine mounts a complete clean of the UIM & LIM and throttle body new timing chain tensioners and now I am about $2000 poorer but worth it I think.

The timing chain cover leak is now fixed so it won't be ****ing oil out now. I already had a lot of the gaskets and parts from Rockauto so that kept the price down.

All up about 10 hours of labour.

REDDYZ · 20-01-2015, 11:37 AM

Nice. Good to see you back on road. Yes its definitely worth.

thearrow · 22-01-2015, 03:19 PM

Took it for a "burn" the other night and man-o-man it has so much more power and strangely it is a LOT louder.

BC1000stars · 23-01-2015, 04:46 AM

That's great to hear! Literally I'm sure! Haha
Cleaning the uim and probably more importantly the lim on our motors is essential, especially for the smooth operation of the IMRC.
Have you blanked off the EGR? This keeps the manifolds nice and clean.
On mine, the v6 Mondeo, Ford actually deleted the egr system from about June 2000. I think they finally realized it was doing more harm than good!

REDDYZ · 23-01-2015, 08:51 AM

This is interesting. I never thought of blocking EGR. EBlocking it gives a bit more acceleration as well. At the moment I have an oil catch can. Which is perfectly doing its job. However the lengthy hoses creates a bit of vacuum lag. I compromised on power to keep manifolds clean. I am interested to see how they blocked off the hoses.

BC1000stars · 23-01-2015, 11:37 AM

The pipes from the exhaust manifold are no longer there, the DPFE sensor is gone, the egr valve and solenoid are gone too and there is a simple blanking plate over where the egr enters the uim. Plus they deleted it from the ecu.
A simple blanking plate over the holes to the uim will keep your manifolds in a much healthier state. The car will throw a code (for restricted egr flow) but is no issue cos there's no check engine light on the ST24.
An essential mod on our engines imho.

I blanked mine when I fitted the st200 (SVT) manifolds about a year ago and don't regret it for a second.

BC1000stars · 23-01-2015, 11:42 AM

I'm unaware if the Cougar has check engine lights on the dash i meant to say, was just pointing out it wasn'ta big issue for me with my car. Different car, same engine.

Davehoos · 25-01-2015, 11:17 AM

English sold cars used different fuel to Europe and during the unleaded changeover loads of vehicles had rough idle issue due to carbon in the exhaust [cold short trips]. Worldwide made Gm vehicles I worked on, and ford like transit often had EGR valve issues. Lots of reasons given for this most of the time a blocking plate would solve the cold start, air flow and idle problem. American cars are often different tune. I worked on a holden that had been reprogramed under warranty to suit Darwin and required to be reprogramed for NSW when they moved back here.

Few different cases to get tuning ideas from.

1 Rodeo would come in with the air conditioning clutch not working. the egr valve was a step motor and if it out of calibration it will emissions limp home mode-without the warning light. it is a step motor you cant remove it without an ECU fix.

2 Brand new Hino O5 Truck over Christmas had a blocked EGR as it is uses to patch roads [very slowly]-the ECU warning flashes for 32 hours then derates the engine. The code is a canbus communication fault. Often owners have no idea this has occurred. until you drive up a hill.

3 Navara with DPF. The ecu has a routine of DPF burn as it drives along the ecu will derate if it obtains the wrong sencor imputs.

4 old engines sold in OZ, often the same engine from japan etc without the EGR. at cruise throttle the ECU/ Carby thinks the engine is under higher engine loads running lots of unburnt fuel. my charade required exhaust cleaning when E10 was used as cat would not fire up.

thearrow · 27-01-2015, 10:32 AM

I am having a few problems now since the overhaul.....when it cold starts it runs rough as guts for a few minutes until it warms up a bit and it has stalled on me a few times at low revs.

My mechanic has checked everything but can't find the problem or at least it is nothing obvious. He is thinking maybe the plugs have fouled even though they are relatively new.

Me thinks a process of elimination may be called for.

REDDYZ · 27-01-2015, 01:35 PM

Sounds more like sticky IMRC bypass valve. Get it cleaned and lubed before thinking of other expensive bits.

thearrow · 31-01-2015, 12:52 PM

Have been doing a bit of research and it would appear that the likely candidate is a faulty ERG valve because the problem is occurring at low revs. The IMRC only operates in the higher rev range.

Maybe ! ! !

My mechanic is going to have another look at it next week.

REDDYZ · 31-01-2015, 01:55 PM

Sorry if I didn't get it right, I was referring to Idle air bypass valve. The one that opens while idling with foot off accelerator And closes upon acceleration. It's an electronic solenoid valve that builds up carbon and gets sticky when cold.
