Hi people. I changed my header tank on a 2004 3.0 SE. I found I could look under the tank and see the level sensor,the bottom hose connection and the evil spring clip if I left everything connected, undid the retaining bolt, pulled the tank towards the radiator and temporarily replaced it but with the bottom 'finger' in the top hole and a thin screwdriver in the bolt holes. There was more room to get a hand under the tank while I pried off the spring clip. Hope this helps.

It was 4 years ago so no link I'm afraid. If you search for 'switchback' there are several kits that look a lot like the one I fitted. Here's a youtube link with a wiring diagram I copied; I didn't do the conversion to make the kit bulbs into 'proper' bayonet fittings; the rubber bungs on the kit bulbs fitted perfectly and have remained in place for 4 years, passing 3 MoT inspections in the meantime without comment.

Lenses crystal clear thank you. The lenses were milky when I bought the car so it was one of the first jobs to do. Followed by an Ebay kit to give me DRL lights hidden in the front indicators. Realistically, I don't see the beam pattern throwing any further; things on the road and verge are just much better lit. For some illogical reason I couldn't stick the mixture of LED and halogen main beam lighting so treated the car to main beam LEDs. It feels spectacular now.

I've been using Twenty20 Compact H7 bulbs in my '04 3.0 SE since September '22. They give a much improved light and and MoT-passing beam pattern. They agree with the canbus system. I chose Twenty20 H7 Twenty20 Compact LED Headlight Bulbs (Pair) | CANBus Ready LED's (autobulbsdirect.co.uk) because there is no bulky fan and the standard headlight covers fit back on nicely. I am aware that LED bulbs in an originally Halogen-equipped car is an MoT failure point, but I took mine to a no-appointment MoT garage, ready to change the LED bulbs out for the standard H7 bulbs and re-present the car minutes later, but no need. MoT passed last November and smiles all round.

My first Jaguar was a 1967 3.4S auto in gunmetal grey with blue upholstery. MAL 400E, did you escape being crushed? I bought it in 1974 and sold my Renault 4 in the thick of the petrol crisis, correctly believing that petrol would never be as cheap again. I was aged 22 then and, during my ownership, made the acquaintance of several young ladies who were tired of being thrown around in draughty convertibles or rusty, unreliable hatchbacks. That old beast could pick up its skirts and fly when required. My next Jaguar was the one I have now, a 2004 3.0 S-Type SE in radiance red with cream leather, bought in 2018. Once again, I'm finding it doesn't show its years when keeping up with modern traffic and it's able to do the 500 mile trip from Yorkshire to my wife's family in Aube, France in comfort. You can use and enjoy Jaguar class at any age you like in my view.

I came to the MoT links above from a different angle. In theory an MoT tester can give your post-1986 car an automatic fail if it's fitted with LED lights, but if you bring a motorcycle fitted with LEDs, it's not an automatic fail. Why not? I emailed the question to the MoT people and was told I needed to refer the anomaly to my MP. I haven't the time or commitment to do so, but I did ask the owner of the garage where I've been taking assorted cars and bikes for testing over the years. In short, his position is that, if the headlamp beam pattern is good and without dazzle, it's a pass, whatever bulbs are fitted. We didn't discuss HID lights, which should only be fitted to cars with self- levelling an with headlamp washers. I decided to fit LED dips to my '04 petrol SE. These are the useful compact H7s from Twenty20 and seem to have a good cut-off and little stray light. I've used them in a fair bit of night driving and not been flashed yet. The beams are good to drive behind with no noticeable dark spots. However, the experience of driving with combined LED dips and halogen mains made me feel so uncomfortable that I ordered the compact HB3s. I chose the compacts because they don't have fans on the bulbs and they fit nicely in the headlamp casings with covers on. That's my two penn'orth.

Just done this mod. on my 2004 3.0 SE. My standards are lower than the joe.dot.com's, being quite satisfied with the rubber surround to the switchback DRL and not attempting any hiding of relays in the fuse box. I am absolutely indebted to joe.dot.com for the wiring diagrams on the Youtube video; it all works perfectly and I have the original indicator bulbs are in the glovebox in case of emergency. I did use Jaguar 4-contact relays by dint of buying an S-Type fusebox on Ebay. I have stock of shielded connectors and they are an uncomfortable fit on the base of the relay shown in Budgie's post; a bigger relay would work better. Having stolen the (small) foglight relay to test the system, I am now waiting for a bigger Jaguar relay to put things back properly. I'm really very pleased with the result, many thanks again joe.dot.com👍

About 6 miles away from Richmond, North Yorkshire.

OK I can tell you that the TEB7AJ relay won't bleep when the LED indicators flash. To be legal it should, but resistors can be added in the caravan to make the relay bleep, or Swift caravans can have a Sargent Electrical box fitted which makes all problems go away. Allegedly. The relay was designed before LED road lights on caravans became common so it needs a bit of work to be legal. P F Jones can supply towbar and relay to your fitter. Good luck and happy caravanning!

Last year I bought a Brink second-hand removeable towbar from Eurojag and had it fitted by a Jaguar independant garage. The rear bumper needs a small piece taking out to give access to the towing plug(s). I've no idea what your contact meant by 'too old'; maybe this is code for 'I don't want the job'. I heard that many towbar fitters don't like to do S-Type electrics because they use a negative earth electric system which they have difficulty understanding. I bought a TEB7AJ relay, which is specific to the S-Type, off Ebay and fitted it myself. Quite straightforward for a DiY project. They system works OK but because the car is so well soundproofed I can't hear the beep from the relay telling me the indicators are working. There is provision on the relay to fit an indicator light. Is your caravan 2 x 7-pin or single 13-pin electrics and does it have LED road lights?

My '04 3.0 SE before and after no. 2 daughter's wedding with polished headlamp lenses and diy mesh grille.

I used to have the click noise from my climate air flaps all the time. I put it down to the car having stood for a while with the flaps stuck in one position before I bought it. I have tried changing the air distribution from Auto to any of the other settings e.g. when at traffic lights with nothing else to do and now the clicking only happens occasionally. Things also improved after I ran the car without a cabin filter and put the fan on max to see if any bits of dirt were dislodged. Some stuff came out of the vents and I was glad I had my specs on!

When I took on my S-Type there was no sign of the long bolt which holds the battery in, just a rusty stub sticking out underneath and a Halfords receipt for a new battery with the documents. The battery was 'held' in place by a daisy chain of cable-ties. This looked like a potential MoT fail to me. Not having seen the system as it should be, I drilled and tapped the remains of the captive bolt in the boot floor and put a new 1.5" long bolt in from underneath. Now the plastic battery retaining block is held by a nylok nut and the threads are inside the boot. So the bolt head can rust all it likes under the boot floor, I won't be touching it again for the life of the car.

Hi all. Back in '73 I had a '67 3.4 S auto. MAL 400E did you survive? 40+ years later I now have an '04 S-Type 3.0 SE auto. It had been stood for a while and had moss all round the windows, dull paint and flat-spotted tyres but it seems to be behaving itself after a coil pack failed and was replaced. Luckily it was one of the ones that were easy to get to. I found and fixed a broken wire in the driver's heated seat and that works OK now. I've had a Brink towbar fitted and made my own mesh grille and it's just had 4 hardly-used Goodyear Vector tyres fitted to replace the cracked 10-year-old Toyos. After several Citroens I'm just loving being a Jaguar owner again!
