Diesel Particulate Filter installed, chassis plates overhead welds done, front spring tower vertical welds don, New ARB Intensity lightbar installed, 'might' have found the the coolant leak - 'could' be the small breather hole on the tank i am currently using for the temp monitoring - have plumbed it using an air fitting to ground so I should be able to rule out any hoses or fittings. Drove the beast around all day and no issues, looking promising at this point. If I ignore the cruise control, I am done and dusted apart from the outstanding instruments still in transit, so HOOOOORRRAAAAY!!!!
