Joppaman Posted April 26, 2013 Report Share Posted April 26, 2013 My car 'boiled over' which I think was due to the electric fan not 'kicking-in'. I removed the thermostat to check it and it appeared to function ok. I then thought I might as well drain and flush the system and so followed normal procedures i.e. removing bottom hose of radiator and engine block drain plug and opened up heater fully. However when I put the garden hose into the aperture of the thermostat housing to flush I was expecting the water to come out of the engine block drain plug - but it did'nt! Do you need to have the engine running in order that the water pump circulates the water around the system (I thought the force of the hose would be sufficient?)? All water that emitted from engine and radiator was clear by the way! Look forward to a simple answer! Quote Link to post Share on other sites
Bill Bourne Posted April 26, 2013 Report Share Posted April 26, 2013 Hi I connect the hose to the heater valve and it works a treat. Best Bill Quote Link to post Share on other sites
stuart Posted April 26, 2013 Report Share Posted April 26, 2013 Take the block tap out and insert a bit of stiff wire in the hole to clear the debris that is blocking it. Stuart. Quote Link to post Share on other sites
fox889 Posted April 26, 2013 Report Share Posted April 26, 2013 Had the same problem & used an old wire coat hanger as Stuart suggests, took a bit of shifting but it cleared in the end. If I were you, I'd also gently flush the heater matrix out then take the radiator out & back flush that, I think you'll be surprised at how much **** will come out..........I was! If you flush everything then you shouldn't have a problem! Good luck Nick. Quote Link to post Share on other sites
Joppaman Posted April 26, 2013 Author Report Share Posted April 26, 2013 Thanks for your replies so far. I did stick a screwdriver into the block hole but was met by a solid wall which felt like the wall of the block! Quote Link to post Share on other sites
stuart Posted April 26, 2013 Report Share Posted April 26, 2013 You do need a bend on the bit of wire to go to the sides of the hole. Stuart. Quote Link to post Share on other sites
Guest ntc Posted April 26, 2013 Report Share Posted April 26, 2013 Or a drill maybe coat time Quote Link to post Share on other sites
RogerH Posted April 27, 2013 Report Share Posted April 27, 2013 Would the use of a flushing compound help matters (Radflush etc).? Or does it just give a superficial clean. Roger Quote Link to post Share on other sites
Joppaman Posted April 29, 2013 Author Report Share Posted April 29, 2013 Thanks again for your comments gents. I will probably re-visit the issue later in the year when I have a spare hour or so! Quote Link to post Share on other sites
