Default 960 losing coolant

Hi I'm new to Volvo ownership and bought a 960 2.5 estate recently and would appreciate some advice.
I bought the car privately sold as seen and discovered a few issues which I rectified ( leaking radiator, sunroof wouldn't slide back)After new radiator was fitted I expected to top up for a few days but level just kept dropping so went into local specialist who said no evidence of leaky head gasket and they advised k seal ....this seemed to do the trick although I developed a split heater pipe so now waiting for a replacement.
My question is...do I keep the car?
It's done 202,000 miles and bodywork is great but I'm wondering if there's a crack somewhere that will eventually get worse.Also had to replace power steering pipe so I have spent a few quid on it.

What sort of specialist did you take it to? They should have done a cooling system pressure test.

Is it automatic? Also have you checked the engine oil level and have you seen evidence of any water/coolant leaking out anywhere? How much coolant did you put in after fitting the new rad?

Loads more questions, these should hopefully give me a few clues which direction to investigate first.

As for K-Seal - it's a last resort and it may have clogged something that needs to be open.

D and A autos in Witney have been doing the work on the car.
Yes they pressure checked the system and no leaking.
Oil level not changed and no sign of head gasket leak symptoms.Yes k seal was a last resort as after discussing with them we decided to go with this due to costs of taking head off etc.
The garage have been great and lent me an 850 to use whilst waiting for power steering hose etc.
My main concern is if there's a crack somewhere that has been 'mended' is it likely to get worse?
I just wondered what others would do?

If they've pressure checked the system and there are no leaks that means the coolant is getting out of there somehow by a means not covered using their tests. If it was pressure tested and i'm guessing the did a compression test for the head gasket or used a coolant sniffer to check for exhaust gases in the coolant and all that came up ok, that really only leaves one item that's been overlooked.

That's the coolant expansion tank cap. Very often it will only let a little coolant out at a time, being hot and suddenly released from pressure, the coolant rapidly evaporates, leaving no trace behind.

I recently had a similar problem, the radiator had given up the ghost so i was hunting for a replacement and obviously didn't realise all the coolant loss was only partially down to the radiator.

Renewed the rad, filled the system, had to top up once or twice as expected but then i still needed an occasional top-up.
One day i noticed some coolant laying in the well round the cap on top of the tank. Thinking it was where i'd spilled some after the recent top-up i mopped it up and thought no more about it - until another dose of coolant appeared there.

As i had a spare cap (albeit a higher pressure than the original) i fitted it to see if it improved matters. It did so i ordered the correct pressure rating and fitted it, job done!

For the sake of £3-4, has to be worth a go!

Chris, some of the 900's were originally fitted with red radiator caps which were prone to internal splits which leaked when hot. If you fit a replacement, make sure its a new green Volvo one.
I wouldn't use any K seal or similar as Scooby says, it may block some part that should be clear; better to fix the problem.

My cap is green but have just ordered a replacement off eBay just in case it is that.
To clarify ..the kseal is already added.
It was in for a week and I didn't lose any coolant for 4 days but then I discovered a heater hose had split ( it was spraying a jet of water at engine under acceleration causing lots of steam)so I won't know if the kseal has worked until I get new hoses on.
The garage didn't say if they tested exhaust gases but they think it's a crack somewhere as couldn't find any leaks .I have patched the hose so I can get to work but it's seeping through so still topping up every day but just a 4 mile commute.
Car still driving perfect..very quiet engine..no overheating( although I have been running a diesel Jag for last 8 years before the 960 so every petrol sounds quiet)..and have the overdraft to prove it

Not sure how I got angry emoji at beginning of my post... wasn't meant to be there.
I appreciate all the advice guys and really like the forum.
I found it by accident whilst researching how to fix my sun roof which I'm very pleased with as the advice I read had me fixing it in 15 mins

I guess you bought the car from someone who knows very well what is wrong with it ..
K seal will not block anything up if you understand how it works , It only hardens when it comes in contact with the air outside of the cooling system that is where the leak is , and it works very well indeed , far better than cheaper leak sealers .. .

The heater hose might well be .... the problem. Having found that needs replacing, and it is not a fortune usually, avoid spending on anything else until that hose(s) has been replaced and tried.

As regards do you keep the car. I was brought up "olde school". If the body is sound keep the car, mechanicals can be fixed.

There are sometimes circumstances to make a different decision but surely most over heating comes down to something that can be fixed.

Only you know the arithmetic of having bought the car. And you might have an idea of the arithmetic of selling the car. That is all....your private business in my opinion.

BUT OVERALL that heater hose is leaking and you are replacing it so I would, wait and see.
