Absolutely positive Kev, known as the KE-Jetronic, it was a Lambda sensor, a module and a cat added to a normall B2x0E K-Jet.

In simple terms it altered the control pressure to maintain the mixture as close as possible to ideal.

However it was a bit slow to respond so only of any real use when idling to get that CO figure down for the tree-huggers that wanted to see less than 0.5% CO (i believe the KE-Jet cars were 0.5%CO and passable even on a cat test at that - also the B200F has an exemption for not passing at 0.3% which is the figure for most other cat-equipped cars from 1/1/92 onwards) but i'm not sure if Volvo offered the KE-Jet on the 240 which is what your link refers to, especially as the 240 was destined to go out of production during 1992, if not sooner.

I think they (240s) were made up until about July 92 in the end but only "by popular demand" so to speak.

The 740s also went out of production about the same time as the 240s so in 1992 the only option was a 940 with LH-2.4 Jetronic equipped with a cat and Lambda sensor.

Given the OPs car is a 1991 and a 940, the chances of it being a B200E with KE-Jetronic are fairly slim, much more likely to be a B200F which was more or less the default fitment to 2.0 740s by then as well.

Going back to the main subject of the thread, as i pointed out in my first post or two, best way is to fit a new timing belt and see what's what.

You might be lucky though.

well.... I've spent 1/2 hour trying to get the cover off, 3 different sized bolts and possibly 4 or... one is a bit rusted.



There's a label from the last belt change which reads B200f but that's not definitive proof.

You will need to remove the power steering belt/waterpump belt and remove the waterpump pulley. Then remove the alternator and A/C belt if fitted.

Then there are two 10mm bolts, a 12mm bolt and a torx screw to remove the top half of the cover.

The bottom half you will need to remove the crank pulley, you will need a 24mm or 15/16" socket and the Volvo locking tool. If you don't have the tool then your best bet is to put it in gear with the handbrake on and use a breaker bar or impact wrench if you have one. Once the pulley is off you can then remove the cover after taking out the 10mm and 12mm bolts for the cover.

Make sure to line the crank, cam and auxilliary pulleys up to their correct timing marks before fitting the new belt.

Belt number is 271713
Tensioner is 463633

If it's a printed label saying "B200F" Ken then it's a B200F and an original Volvo label for the engine. Have a look at your fuel injectors, are they fed with an electrical connection as well as fuel from the fuel rail? If so then it's definitely a B200F.

I don't think they did K-jet in the 940s Dave, I could be wrong but I've never seen one myself, I belive they were solely LH2.4 or diseasel.

I know they offered it in the 740 Luke, not sure on the 940 but as i said to Kev further up, chances are it's a B200F, i wasn't sure at first but as it's a 1991 it may have been a special order or something silly - you know what Volvo are like for either offering things or changing them or whatever!

I also wouldn't put it past Volvo to put 940 badges on a 1990 740 with a B200E K-Jet and sell it as a "special" 940!

Of course, if the 7th and 8th characters of the VIN number are 27 that will also tell you it's a B200F engine.

I checked the service records yesterday, (Friday) the PDI was done on 18th September 1992 so it's 29 years old today.

The first and it seems the only cam belt change was done at 107000mls
It lasted 60000mls before it let go. (167270mls current )

The broken one is a Q&H so although the recommended period is 50k mls between changes, it is nowhere near the 107k the original lasted. (thats assuming it wasn't done in between and not listed on the records)

My son had a belt fail on a 1.4 mk4 golf (no real service history but it had done 75kmls) I changed it and replaced valves etc and, the replacement belt broke after 50000mls. Point being after market parts are not as good as originals.

I will post when I've changed the belt whether there's any engine damage, that will be a reference for any other owners who ask my original question, namely, is the b200f a non-interference engine.

Regards ken.
