I have a Carry Dump (F6A 657cc)engine with a coolant leak just above the oil filter from a hole that looks like something should be in it (sensor/drain valve). For the life of me I can't find any reference to this hole. I pulled the radiator and timing belt cover thinking it was a drain hole for the timing belt and I had a bad water pump - I was wrong on both accounts. The hole appears to be plastic lined and not threaded. Can anyone help?? Please see attached photos. https://www.dropbox.com/s/3fpdmm5nfu11kwg/2019-09-07 16.26.25.jpg?dl=0 https://www.dropbox.com/s/q33x0ucuu927664/2019-09-07 16.26.14.jpg?dl=0 Thank you in advance! - Jim
Update: Worked out what the mystery hole is. It is the "weep hole" for the water pump which is in place to give you indication that your water pump is on its way out. Hope this helps others that nay be scratching their heads.
