Anyone familiar with this rattle sound? It can't be generator as I just replaced it. In my memory failing bearings have different sound, but I might be wrong. In the very beginning it's easiest to hear the sound, but it also happens later.

 

My GUESS.

That belt is WAAAAAAY too far into the "V", meaning it is OLD and worn. When a belt touched the bottom of the "V", strange sounds are made.

So, I would replace that belt, then try again.

I may be way off, but all the same, that belt is nasty looking.

 

I think Grant is correct re the belt.

If you put a little hand soap or silicone grease on the belt edges (whilst the engine is stationary!) and the noise changes when you re-start that may confirm. The noise will return soon after as lube rubs off. I use this technique on my old Volvo that has three belts to check which one needs attention.

Belts can make weird sounds. Rattles, whirs, squeals, ssshhhhh sounds. "Belt knock" can even sound like a crankshaft or connecting rod bearing failing! I kid you not !

Make sure to spin the pulley/pulleys while the belt is off. If the pulley bearing is failing, you should be able to feel it.

Thank you very much gents!

The whole black friday-monday I was thinking "what do I need buy, will probably find out when sales are over" - here it is! :-)

 

Anyone knows what part number is this belt by any chance? It goes around crankshaft, water pump, air pump, and generator. I am looking at catalogs and belts there only go through 3 things.

 

My memory and listing show 3 belts on a 3.6.

Crank - water pump - alternator = EAC3850
Crank - A/C = EAC3878
Water Pump - Air Pump = EAC6335

Thats it from all I have ever seen, mostly XJ40, but the same layout.

 

What can I say :-) ( Is it possible that previous owner did this 'art'? This is how I got it. ).

 

DUNNO.

Maybe its my old age, or the fact I only have one eye, or the angle of the dangle of the snap, but that belt doesnt look right to me. It looks misaligned a little??, or its me.

BUT

I dont see the 2nd "V" on the water pump pulley to drive that air pump (we never got the air pump here, so 2 belts only), and YES, the water pump only had ONE "V" for our market. Also the 3.6 here was NOT in the XJS, those cars were private iimports, usually from the UK. Both my XJ40 (3.6) had the 2 belts.

I know your market got some weird stuff, but that just does not look right to me, and I will stand corrected of course if thats how it is.

 

Doesn't seem to be very much belt contact on the water pump pulley. Are ya sure that's the proper belt config?

 

N2003XJ8,

Do you know if your car is one of the tiny number of Jaguar "evaluation" vehicles brought into the US, that then "escaped" into private ownership instead of being returned to the UK, or is it a private import from another country?

It seems to have an air emissions pump, but it doesn't have the expected twin-groove waterpump pulley and second belt that would normally drive that air pump?

I wonder if the air pump was fitted when imported to meet the US requirement and configured so that the air pump pulley lined up with the waterpump single-groove pulley so that a longer single belt could be sourced to link the crank, waterpump, alternator and air pump?

Hmm... I am only sure that this is how I got it. All I did is removed fan with the clutch and installed electric fan.

Hope someone else here has similar 3.6 configuration of the same era and can share how is his/her belt routed. My understanding is that this configuration was a 'test the US market' batch of EU-bound cars fitted with US-compliant emission control system. Perhaps air pump was part of DIY emission kit :-)

 

I've heard something like that, but never heard that cars were supposed to go back. My understanding(based on rumors) was that they were used by dealerships as test or courtesy cars and then sold to anyone who wanted, it just happened that mostly dealership workers bought them.

 

I'd read many years ago that the (25?) 3.6 cars were brought into the country under some loophole because they didn't meet full US specification and therefore had to stay as evaluation vehicles under the ownership of Jaguar. Bust as we know, some of those ended up in private hands. I'm not even sure if they were given the secondary US VIN or remained with just the primary VIN? Does your car have a secondary US VIN?

Paul.

 

I don't think so. There is one VIN under glass, sticker VIN matches, and that's the vin on registration. On the sticker it said Imported By " V.I.P AUTO SALES INC. " I did have issues registering as dmv system didn't want to accept vin, but it properly decode to US market per jaguar website.

 

N2003XJ8,

Ok, if you're saying it decodes to US market, then that's the secondary VIN that was given to cars destined for the US. You might find the primary Jaguar VIN stamped into the horizontal panel on the bulkhead just in front of the windscreen scuttle drain panel. (The panel which is just covered by the traliing edge of the bonnet (hood) when closed.

That MIGHT seem to make it one of the tiny batch of evaluation cars. And perhaps that is the way they added on the air emissions pump and did the belt configuration?

Cheers

Paul

 

Actually, my apologies... I was talking about different vin... this one starts with SAJJNAEC8CC , according to this: https://www.jaguarforums.com/forum/g...tables-145996/

C in position 11 stands for "Middle East - Emission D" , whatever that means.

P.S. While I was looking through papers and repair manual that came with the car I found part ID hand-written next to the belt replacement paragraph. Ordered it, and if it fits - I will share the part ID.

 

That makes it sound like a grey-market car and not one of the evaluation cars.

Hmmm.

Interesting. Some pics of the car, engine, and VIN tags might help. All the grey market cars I've seen were pretty easy to identify as such.

Cheers
DD

 

I'm not an authority but that's the opposite of what I've heard! My understanding is that the evaluation cars were 100% compliant in all respects: emission, safety equipment, lights, bumpers....the whole tamale.

Gah !

Cheers
DD

 

Back to the original issue, the noise. I believe it is the Air Pump, or as we lovingly referred to them here in the USA, Smog Pump! I've heard many of them make exactly the same noise. Look for a split hose, to or from the pump, as that's usually when you hear them. But they can make noise even if the hoses are good. Hope it helps.
