They're the engine oil cooler pipes. There's lots of threads on here (search) about these leaking through old age. The good news is they don't have a reputation for blowing off but can involve replacing the oil cooler as well as the pipes if you fix it the 'proper' way. I've put a cheap and...

There seem to be two different sizes quoted for the diesel a/c belt 4PK855 and 4PK836, the number does relate to the circumfrential length. There are two tapped holes for the tensioner to fit to; I don't know if the two belts suit the different positions or why that would be necessary, one of...

Mine wouldn't loosen despite much shocking in the correct direction. I had to get the fan off because it had started to shed blades so started chiselling off the remainder - hay presto - the thread came loose. Now running without a fan and the electric fan mod - thanks for that advice, its...

I live in the North East and my pump packed up completely about a month ago, maybe its the driving up the map that does it? The indy that fixed mine said that sometimes you can get an extra kick out of the pump by bashing the base of the tank with the heel of your hand. And if it starts it...

Petrol or diesel? I can't help directly but have found with my diesel and both son's BMW Z4's that the O rings are (unsurprisingly) metric. Measure the diameter of the cord, usually 3.5 or 4mm for bigger diameter rings, and the inside diameter of the ring. Your local bearing supplier will be...

Bumping up this thread with more information. I tempted fate too much saying my oil filter cap didn't leak. After the last oil and filter change it started to weep. I lifted the cap and fitted a new filter and seals. I found, as said further up the thread, that the O ring was distorted, there...

Have a look at the excellent guide with pictures here; P38A Instrument Panel Removal The little bulbs don't have a long life and while it's not too hard to do I went for long life LED's. They are very directional though and shine through too brightly so I put a blob of paint on the globe end to...

It's right handed and F tight. You have to peg the engine to stop it turning.

I'm half way through doing Datateks fan mod after finding broken blades and a hole in the cowling where a blade has done it's own version of The Great Escape. VC felt free but there was definitely a vibration and whirling noise as if the fan was being driven continously - and has overspeeded...

I hesitate to have a different view to others on here but in this instance I do. I've done this job for both seats in less than a day. It's not too hard just a progressive step by step thing. There's links to other threads and a good illustrated guide here -...

I'm trying to help the 'leaky' guy, mines fine. Yes I'm putting the O ring right in the groove. I probably could get the cap on by hand but with oily hands I find it's easier to turn with the chain wrench - I haven't got a scaffold pole on the end, it just helps the grip. The hex on the top...

Yes, my cap has a hex but it’s really thin plastic and looked like it would shear easily with the torque needed to get the ring to enter the housing. A chain wrench just above the thread works fine, besides I haven’t a socket that size! I guessed that the filters were different but...

I've used a few different makes of filter but never (I know that's tempting fate) had a problem. I put the cap back on with a chain wrench and can feel the extra tightness as the O ring enters the housing. A little oil on the ring helps prevent tearing and lets it settle in the right place. I...

OK! It sounds old now I read it myself, and I don't know how many miles it had done before I got the car. It does look OK though with no cracks in the ribs. My experience with the other 'new' one has detered me but maybe I should get a good named new one this time and perhaps a look at the...

My Alphaline has been fine, two years, two winters and 60K miles. No affiliation just a satisfied customer.

Changing the belt is a bit of a fiddle but not too hard once you figure it out. Have a look at my experiences here http://www.landyzone.co.uk/lz/f10/how-change-2-5-diesel-serpentine-belt-185926.html Make sure you fit a good quality belt, I replaced the one that came on mine; the 'new' one only...

Our P38's have a reputation of giving us things to do, some of these despite lots of guidance in various places on the interweb (thank you) aren't straight forward arm chair ride type jobs. Bucking the trend (and I know I'm tempting fate here) mine has been pretty reliable and the maintenance...

I'm not keen on the appearance but would like to keep the ****e off the car and they look like they would stop your doors getting bashed by Mrs Clumsey in the supermarket car park. I notice second hand ones often don't have brackets. How about concluding this with a sketch of the bracket, the...

This is the same regulator, from the same supplier (no affiliation), set at 14.7v that I fitted to mine as per the response above. It runs around 14.4v once the start up drain is recovered and about 14v with lots on. Two years and 60K later it's been fine with no flat batteries. You can't be...

That doesn't look like the one in mine (but yours could be different), it definitely didn't have the three pin plug and integral brushes, just soldered in terminals and the two threaded post terminals. From memory mine looked more like this; NEW VALEO ALTERNATOR RECTIFIER RENAULT VOLVO 2043 |...
