simple coolant flush/temp sensor/speedo needle
Posted: Thu Oct 25, 2007 6:01 pm
Got around to doing a few bits on the bongo today, most importantly - a coolant flush. I ended up using a similar method to BDC's I think, I figured if I don't let the head tank empty, I'm not gonna end up with a possiblity of an airlock.
I got my hosepipe ready with a trigger nozzle & topped up the header to the top.
After 10 minutes frigging about getting the plug out of the bleed pipe (supposedly done in march when it was imported - didnt look like it'd moved for a looong time)while holding it above the level of the header tank I stick my nephew on the end of it (not literally
), as he lowers it down & it starts draining, I keep the level of the header up with the hose pipe, which I then set on a constant flow using the removable zip tie that held the bleed pipe. Set the flow so that it's just overflowing the header, observe horrible brown crud pouring out of the bleed pipe, then start the engine & observe another wave of crud coming through
After 5 - 10 minutes ( a few minute at 2500rpm just in case)get the nephew to stick his finger over the bleed pipe, take out the hose from the header, gently allow it to empty to just above the bottom, fill with antifreeze & repeat until sufficient antifreeze added, I went for 3 litres. Then gently drain while keeping the header topped again with the hose until the antifreeze can just be seen starting to drain out, stick the bung back in & box it up job done, making sure to thoroughly hose off any antifreeze that may have dribbled around the header.
Much simpler to do than it was to explain
I also fitted a cheap digital temperature sensor from ebay( same as Brorabongo I think), but stuck the sensor in just above the dipstick with some silicon that has a max working temp of 150 degrees, seems to work a treat, highest temp after a good 20 minute run was up to 98 degrees.
Can't remember who said about taking the speedo needle off & putting it back on so it reads more accurately, but it's worked a treat, couldnt get it quite right so stuck it on while on the move at a constant 45mph according to my gps thingy, just about spot on
I also got around to wiring my front fogs in to my remote central locking flasher thing while I was messing about with the dash.
All that without having to get dirty either
