Stockist/cheapest for coolant/auto box oil

[Nomis]

I am planning on doing the auto box oil change and coolant change before the really cold weather.

Where is the best place to get the OAT coolant and texaco N402 gearbox oil?

Just been to Halfords but do not stock the texaco oil and there own brand coolant was £9.99 for 2 litres and I will need 8.2 litres so that will be pricey.

I will even buy online if thats the best price.

Hi Simon,

The gearbox oil can be a bit of fun to locate sometimes so try XPart and Land Rover dealers as well - the same box is used in the Freelander

[Lates]

Anti freeze is around £12- £15 for 5 litres. Comma Xstream is the same stuff if you cant find a dealer.
Gearbox oil a bit more rare, expect to pay around £20 ish.

N402 Auto Fluid ( Part No.VYK 00040) was out of stock but understand Xpart have it again. Lates is correct, it was £20.70 / 5 litres + VAT so not expensive. Land Rover have same : Part No LNR402
Xpart also have O/E antifreeze. About £3.25 per litre (mix 50:50) which I think works out a lot cheaper than Halfords OAT ready mixed

Is the N402 auto oil essential or will another brand do the job? My local motor factor shop had an equivilant and sold oat antifreeze but did not see the brand or ask about prices but he is usually cheaper than anywhere else round here.

While I am on the subject, anyone got any tips or pointers for doing the auto box oil change? Never changed oil in a gear box before, auto or manual. Is the filler easy to get to for example?

Coolant should be easy enough as I can see the bleed valve on the hose at top right.

I intend to do as much of the servicing and repairs as I possibly can as I know whats been done that way, plus I actually enjoy doing it myself.

I would use this oil as an essential, the gearboxes are fussy on their oils and very expensive to replace if it goes pear shaped.

I will get the texaco stuff then when the main dealer opens tomorrow. Seems strange that it is not stocked in many places though. I may as well get the oe coolant at the same time too since I am going.

Yes Waj, only use the N 402. People loosly claim 'it's the same' but it is not.
I did a lot of searching on the subject with, initially, Ashcroft Transmissions telling me to use Castrol. I then actually contacted Castrol. Their reply " We do not make a fluid suitable for the Jatco Box"
Apart from Land Rover, several Japanese cars also have Jatco boxes and Jaguar have also used them, They all probably sell The N402 but it will be in their own branded pack as is the Rover Fluid.
I have heard that Jatco boxes operate at high temperatures. Whether this is true/different to others I don't know but i am informed that N402 has additives not present in other brands.
On reliability/cost/preventative grounds I intend to change every 30000 miles, not 60000. It is not prohibitively expensive. (about £40)
Unless you are completely happy that you can carry out the change as reccommended I would strongly suggest you take it to a GOOD auto specialist. The temperature on refilling is fairly critical.

When you say temperature on refilling do you mean engine temp or does the fluid need to be of a certain temp? I have read how to do it and it is easy to get to the drain plug so it should not be a long job once up on axle stands. I am not keen on specialist prices to be honest.

Can you explain what I have to do that is critical? I have read the how to pdf from here and have details from the workshop manual too.

First paragraph on page 2 of the PDF states temperature of fluid needs to be between 35 and 45 degrees centigrade to obtain a correct level reading.
Engine temperature is arbitrary.

Hope this helps

This will help yes. Though I am sure not all garages will do this before filling them as they will probably not be NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-! I will make it the correct temp or as near as possible before refilling and make sure the correct amount is put in. I will see what comes out too as sure its not been changed bfore now. Its just done 60k

I would suggest in any event that after refilling and running the vehicle for a very short test trip that the level be checked and topped off if necessary. Just in case the fluid cools below the required temperature while filling takes place. Call me pedantic but better safe than sorry

Thats a very good idea. I will have the cover off all day anyhow saturday as doing the oil and filter and also the coolant change.

I will do it properly (hopefully) as thats the whole point of doing it myself as then I know it has the correct fluids in there and I know it has been done.

The air filter is so black at the moment you cannot see any white bits so not sure when that was changed either, but got a k & n on its way to solve that.

Will the auto oil expand when warm then? If so if it is warmed to within the temp range and checked to make sure will it be the recomended capacity while at that temp or is it the recomended capacity while cold? Confusing!:confused:

While I am here, the refill plug, is that located above the box at the front end near the battery with a rubber plug? Only had a very quick look so far. The diagrams are a little unclear.

Not done the job myself, perhaps someone like Lates is the bloke to double check with, PM him with your questions, he will pick it up later on this evening when he logs on.
The fluid will definitely expand when hot. It seems to me that filling within the temperature range stated will prevent overfilling, which would be bad news.

Thanks for that. Makes perfect sense to me.

I am not doing it until the weekend (if my MGR dealer has it in stock) so gives me plenty of time to suss it out.
