Prestone AF-KIT Flush 'N Fill Kit

Product Information

Prestone ® Antifreeze+Coolant protects you from these experiences by preventing engine part failure. The cooling system should therefore be properly flushed on a regular basis – when the water pump is replaced at the very latest.

You should keep an eye out for any potential signs that your car may need a coolant flush sooner than this. If you’d like us to drain and refill your coolant for you, you can book our Coolant Change service at one of our 600 garages.Buildup in the cooling hoses can cause major problems such as slowing coolant flow, reducing cooling and even clogs in the system from loose corrosion. Option 2 - drain old coolant, remove cap from "flush fitting", connect hose to fitting, run fresh water through the system until it comes out clean, drain water, remove hose from flush fitting, replace cap, refill with new coolant.

Draining the radiator alone does not sufficiently remove old coolant, as the radiator may contain 40 percent or less of the coolant. Coolant capacity, I only know the capacity of my B8 S4 and that became obvious only when I drained it down, someone in another forum quoted refilling a B8 S4 with 6 litres so I bought in more than that. It can cause leaks: Over time, small pieces of metal from your engine will contaminate your coolant, causing damage to parts like your gasket seals and hoses.Rust and dirty coolant that circulates in your car’s cooling system can lead to a clogged radiator, resulting in overheating and engine damage. Over time this can cause leaks that will inhibit your car's performance and might mean you need to replace your radiator (although there are some other causes of leaks you should be aware of). In the final step, the cooling system is filled with new coolant and ventilated, making the system fully functional again.

Everything’s fine when the system is new and the radiator core tubes are clean and free-flowing, but over time these very thin tubes can become contaminated and clogged. It can be difficult knowing what the best way to flush a car radiator is, with a lot of different advice out there to follow.Yes, but bear in mind it's just a schematic showing pipe routing - so actual placement of parts might be off a little. Snap the splash deflector tube—the largest tube in the kit—into the radiator neck where the cap ordinarily sits. But, in general, most mechanics will recommend a routine flush every two years or when you reach 40,000 miles, depending on which comes first. Collecting the old coolant, I bought a new plastic bucket from Screwfix, I think that it is maybe a 12 or 14 litre one which makes it quite low in height, it was seriously cheap as was the plastic funnel I bought with it for decanting the old coolant into the 5 litre containers - really mainly to quantify the volume and to hold onto it in case I ended up with serious leaks after having taken the pipes apart, ie to use until everything was water tight if it started off not being - really belt and braces approach I suppose - too much time on my hands as I'm retired!
