joste Posted August 8, 2016 Report Share Posted August 8, 2016 HI all I have a overheating problem, I have tried flushing the system twice , but the strange thing is nothing ever comes out the drain plug on the engine only on the rad. If any body has any ideas would appreciate them. many thanks Steve. Quote Link to post Share on other sites
Kevo_6 Posted August 8, 2016 Report Share Posted August 8, 2016 Hi Steve I had the same problem a few years back and I had to get a wire pick up and around the jacket and keep dragging all of the **** out, it was a bit easier for me at the time as I also had the head off and I could go in from the top too. I have also read on here that others have used some sorts of flushing agent! Quote Link to post Share on other sites

Tim D. Posted August 8, 2016 Report Share Posted August 8, 2016 Same issue.. Use of a wire coat hanger.. Lots of **** came out including loads of the original casting sand! Tim Quote Link to post Share on other sites
ShaunC Posted August 8, 2016 Report Share Posted August 8, 2016 Remove and check the operation of the thermostat in a pan of water with a thermometer. You may not be getting sufficient flow through the stat and therefore radiator when you need it?...They are not expensive so maybe change the stat to rule it out if you can not measure the temperature?

Sapphire72 Posted August 9, 2016 Report Share Posted August 9, 2016 As Tim D. says, prod around in that bolt hole orifice on the side of the engine block with a tough wire. Move the wire around with great vigor, as you replenish the radiator water supply (garden hose running). Also: Observe the flow of fluid with the radiator cap removed, and warm engine running, thermostat open. If fluid flows gently/evenly from right side to left side, then your water pump is doing its job. If fluid surges, then your water pump may need to be rebuilt or replaced.

Sapphire72 Posted August 9, 2016 Report Share Posted August 9, 2016 You should have the radiator drain closed when you are trying to flush the block hole. It was not clear if this was the case. Quote Link to post Share on other sites
joste Posted August 11, 2016 Author Report Share Posted August 11, 2016 You should have the radiator drain closed when you are trying to flush the block hole. It was not clear if this was the case. Thanks Sapphire72 that was one thing I did not try,But idid try unblocking the engine drain hole today and are now getting the very slightest drips of water, so maybe there is hope yet. Many thanks Steve. Quote Link to post Share on other sites
