Installing a Twine

Coolant isnt that expensive, and never hurts to refresh it... Most of its the same, bottled in Horsley Park Sydney... I used to deliver tankerloads from ICI in Botany to there! they only have 1 Vat, and around 5-8 different brands of bottles and boxes come out of there...

Just dump it out, and fill it, run the engine with the rad cap off, and refill as needed....

You should be changing your coolant every 18 months maximum as it goes acidic like vinegar.
Make sure you use a main line brand like Mobil, Shell etc that is concentrate, and then mix to the correct ratio with de-ionised water from the supermarket.

You should change ALL the fluids in a vehicle between 12 and 18 months, and preferably no later than 15 months. Cheapest maintainence you will do and saves a lot of money in the long term.

Just brake bleed all four wheels and see what gunk comes out of the brake system, and you will see why it is such a good idea to change ALL fluids in a vehicle.

Tim,

When I installed a Glind shower in my 80 series Cruiser, I tapped into the coolant line up next to the valve on the firewall that is controlled by the interior heater control. I didn't have to cut any hoses. I just changed the direction of the elbow and put in a connector. Because it was at a high point in the system, about the same hight as the top of the radiator, I lost virtually no coolant. If you keep at least part of the connected hose higher than the rest of the plumbing the coolant won't flow out. Then there's the old "Boy and the dyke" method, stick your, or an assistants thumb over the end. This works best when the coolant isn't boiling hot obviously.

Cheers,
Ian

P.S. I highly recommend those pop-up shower/change tents that fold up into an almost flast circular bag. About $100, but great value. 5 seconds to set up or take down.
