Clever ways to economically keep an old car roadworthy

Hi motors

The GFs 13 year old Astra needs a bit more nursing and this got me thinking.. If I share the ways I've managed to keep the car on the road without breaking the bank, maybe others could share their knowledge by adding their clever fixes. Just to clarify, I'm talking actual repairs, not sawdust in the gearbox type bodges just to enable a quick sale, but having said that I'd also be interested to hear about any roadside brainwaves people have had to enable them to continue their journey, pending a more permanent repair.

Back to the Astra:

Just about to head home from a weekend down in Torquay and there was suddenly a terrible rattling sound..

Problem: Exhaust backbox heatshield had corroded away at the fixing points and was wedged between the backbox and the floorpan of the boot.

Solution: Bought pliers, screwdriver and a can of coke from a one of those discount shops for less than a fiver. Fashioned the base of the can into a large cup washer and used the middle fixing point to support the heatshield. Drove home without so much as a rattle and fixed it permanently at home with proper washers front and rear.

Problem: Oil sump drain plug seized.

Solution: Bought a neat little 12v pump from Germany online for £18 that allows the oil to be pumped out via the dipstick hole. Also the oil filter is high up on the front of the engine so oil changes couldn't be easier now! 4 oil changes on and the pump is going strong.

Problem: Coolant expansion tank filler cap stuck on. It can be loosened when engine warm and gases escape but can't be removed, it's jammed on.

Solution: remove both hoses at the radiator that lead from the expansion tank (feed and return) and secure above the level of the expansion tank. With a little funnel inserted in one of the pipes, top up the coolant while the other pipe acts as a breather. Then reattach the pipes to the radiator.

The GF loves this little car (I know, it's an old Astra), no doubt something uneconomic to repair will come along, but until then it'll be pumps, funnels and whatever else I can think up.

Please share your clever fixes.

In these cases is it not easier to just replace the offending parts? With the likes of Eurocarparts and their DFS-style perennial discount codes, parts for older cars are dirt cheap and if you are handy with car DIY, it's not expensive to keep older cars on the road without having to resort to random bodges. Larger and/or catastrophic failures excepted, obviously.

Must echo Howard, parts prices are so cheap that i'd always replace everything properly even if for pattern parts on old/cheap cars. It is mechanic labour and need for specialist tools/lifts which gets you if you cannot DIY.

Just as an example, a new coolant expansion tank and cap for an Astra of that vintage will cost you £22.06 after discount from ECP.
eBay (new) pattern one for an 07 Astra is £9.99 delivered (full tank with cap), so cheap that he might as well chuck a new one on if they plan to keep the car for more than 5 minutes.

Point taken, I will replace parts where necessary, but seeing as I've already topped it up (it took 3 years to get from max cold to min cold) and can top it up again in future if needed I don't think it's necessary to buy a replacement part for such an old car.

Firing the parts cannon is not always the best way to solve a problem :)

Alright big spender!

Genuine Vauxhall part (albeit used but who cares) - £6.95 delivered :p

But yeah, got to agree. With eBay/ECP - it's not good sense to bodge these jobs when the proper fixes cost so little. I could understand if a new expansion tank was £200 and a dealer only part, but when you can get a new one for less than a tenner, why would you bodge it?

The header tank is knackered. A new one is a tenner. It's hardly "firing the parts cannon".
Why would you bodge it for ten quid?

Sounds like ‘ways to make up for mechanical incompetence’. Seized bolts are not a stopping block, just an inconvenience.

Whilst i'm sure this thread was started with the best intentions, I had a sneaking suspicion it would be met with responses like all of the above :D

... preventative maintenance too, but, maybe the astra is new to her/you ..
changing the oil every while , and checking coolant (every time I check oil/water) would prevent seizure ? , and, a once over, regularly.
trickiest seizure I had was wheel stuck on hub... but it's now well copper greased.

13 years!

In my world, that is a new one!

(Oldest car = 50. Series II Land rover, oldest daily drive, 1994 Landcruiser)

:D

Back to the Astra, you do not say which engine.

If it is a petrol 12/16V one, ensure that the little coolant water connector on the top of the water pump (Next to the coolant temperature sensor) has been replaced with a brass one.

Some early ones were plastic and they have a nasty habit of just snapping off randomly causing a LOCA incident which will, at motorways speeds, destroy the engine in seconds (For some reason, these engines are not particularly heat tolerant, seen it happen many times)

If you try to replace a plastic one, it will almost certainly snap when you try to replace it but carefully drilling out the plastic and cleaning up the threads with a suitable tap is an easy job

(If you make a Horlicks of it, Worst case scenario, just replace the water pump. They typically come with a brass connector and a coolant sensor already fitted)
