V70 2.5 TDI 1997 workshop manual

[Aubergine man]

Hey folks!

I hope I'm posting this in the right forum. I have recently got my first car, V70 2.5 TDI 1997 and am keen to learn about it, service if myself and do minor repairs too. Only problem is I'm a complete beginner at car mechanics and I can't seem to find a workshop manual for my model. I've found the Haynes manual for the V70 mk1 petrol and the one for the MK2 diesel but my mk1 TDI doesn't seem to have a manual? Any suggestions?

Currently I'm just trying to flush and change the coolant but I'm not sure where to find drain plugs. Owners manual says I need to find three of these!

Thanks for any help!

Most of us just pull off the bottom hose to the radiator to drain the coolant, as the little taps can tend to break off when you try to use them after so many years. The hose clamp on the bottom hose is prone to corrosion, so unless yours is in good condition I'd probably be looking at replacing that too. Get a stainless one if you can, any decent hose clamp of the right size will be fine.

Hi luxobarge,

Thanks for your swift response. I actually tried what you suggested first but not that much came out (I didn't catch it so I'm not sure exactly but I'd say at most 2 to 4 litres) I started filling it straight up with concentrate but it took less than a litre before reaching the level and I didn't see any gurgling or air coming up so I figured something was wrong. Having now looked at some you tube videos on similar cars (Volvo 850) I'm seeing a much more complex process involving taps, removal of thermostat, running the engine (this videohttps://m.youtube.com/watch?v=LSvcEYoYNCo if anyone is interested). Good point about taps breaking off I hadn't even thought of that when I started trying to follow the instructions. I might just try flushing with water with the bottom hose off and see where I'm at after that.... Any other suggestions welcome!

Firstly - don't fix what isn't broken - why are you flushing the cooling system??

The car itself is largely the same as a petrol car so the petrol manual will guide you with everything except the engine.

An Audi A6 manual which covers the AEL engine will give you the rest.

Ha! Very good point ni volvo nut! I guess what happened is the guy who had the car before me tried to replace one of the hose clips and ended up accidentally pouring a load of the coolant out (as far as I knew it had all come out) and replaced it with water. He told me I had to "do the coolant" urgently which my asking someone else led me to understand it as changing the coolant which YouTube led me to understand as flushing the coolant and here I am a couple of weeks later with loads of coolant trying to flush the system by unclipping the bottom hose but only getting less than a litre out at a time. I've poured water through till it runs clear and I'm tempted just to top it up and now and take it for a run. I guess my only worry is if I have lost more than I've put back in and whether that will cause problems. also I'm wondering whether the fact that less than a litre coming out of the bottom of the radiator is a sign that there's a blockage somewhere that I should be sorting out.

Re manuals, thanks! That is exactly the info I was looking for. Going on to ebay now to find those very books!

Thanks all!

If you do decide to flush?
Posted this a number of times but just in case it has been missed: ~
Central heating descaler is ideal for flushing car systems- just follow the pack instructions- it is safe on dissimilar metals. Bring up to temperature a couple of times to gain the maximum benefits – far better than any branded radiator flush.
Regards Bob.

What so empty the system, flush the descaler through it then water, then fill it all up with the right stuff? Good shout. Thanks. Although it's academic unless I can flush the system at all in the first place. On that note do yous think it's safe to run the engine with the bottom hose off and water running into the reservoir to try and flush more stuff through?

There is a small hole to the right hand side of the front plastic cover tray as you look from the front underneath. The tray that covers the bottom of the radiator. There is a plastic plug that you undo with i believe a 14mm socket. You can't see the plug as its an inch or so up. You will need a small extension too. Just undo that and most of the coolant will come out. You don't unscrew it all the way out, just several turns. I have never had one break but you never know, so just be careful !!

[Aubergine man]

Great thanks. yeah I found that plug. I'd been trying to get it with an allan key but I'll try the socket then. No need to take the plastic cover tray off right? In the video I watched about the 850 the guy talks about another tap or plug up behind the axle. Does that exist/it's it necessary to open too on my v70?

You can do the above- BUT you do need to watch the heat build up- I wouldn't recommend this however as you will gain nothing.

Drain and fill the system with the new descaler (mix with hot water if you wish) seal the header tank and bring up to temperature-- allow to pickle then build up temperature again. Repeat as necessary, drain as previously advised.

Drain & fill with clean water- Drain again but this time keep flushing via a garden hose.

Once satisfied that all contaminates are removed you can move on to the normal fill/antifreeze procedures etc.

(I would leave the rear block plug alone)

Not as long winded as it sounds.
Good luck
Bob.
