Hey now I know this seems a real simple question, but I had the car on a ramp the other day and wanted to do a full coolant drain and refill, but I couldn't for the life of me find any form of a drain plug, and all the information online seems to be for the petrol engines which I assume have a different radiator to allow for the intercooler, I ended up pulling the hose at the bottom of the radiator, but I ended up only draining about 1l of a 5.6l capacity system. So does anyone know for sure if there is definitely a drain plug and i'm just being blind, or is there no plug and I need to follow some different procedure to drain the system.

 

Thanks,

No drain. Just pull the bottom hose off. Then run engine briefly, that will kick out most of the remaining.

Ah my tutor basically nearly shot me when I proposed running the engine with the hose off, don't know if that was due to him misunderstanding what I wanted to do or what.

If you've got the original  Ford antifreeze in then it's got a 10 year life. Leave it alone  is my advice. On  my Mondeo there is a drain plug on the engine block itself but it's very inaccessible. The best I've ever done is drain the top half of the engine when I replaced the pump and 'stat. 

Buy proper Ford antifreeze, its not expensive and you mix it 50/50 with deionised water (well, I did)

The information I read from the ford documentation is every 6 years or 100,000 miles, and I just hit 6 years in it, and yes everything i've put into it is genuine ford, it's the first service since owning it, so I don't know for sure it's service history other than it was main dealer stamped every year since new, but I decided i'd do everything, inc Brake Fluid and coolant so I know for sure the date everything was last done.

The previous poster was correct. It is 10 yrs the change interval and no mileage limit.

Fair enough the information I got must've been incorrect, I can't remember at this time where I saw that, but as i've mixed old and new when I drained the radiator and not the whole system, i'd still rather at this point do a complete flush as I've still got 2l of concentrate and they're already mixed down so can't be returned, all i'd need is another 1l of concentrate to be able to do a whole system anyway.
