I got myself a Bongo in May it is a 1997 2.5d conversion. Everything was going good and the Bongo life was awesome then I started getting cold start problems about a month ago. I replaced the glow plug relay on the advise of a mechanic {he also checked the glow plug and said the where working fine } I'm not sure where the fusible link is because of rewiring {photo attached }

The mechanic suggested that I fit a switch to heat the glow plugs up first before starting the engine but I am not sure of the safest way to do this .
Part 2
Then last week as I was coming home the temp gauge shot up to full and I started hearing a gargle coming from the front and the engine . When I looked under the bonnet the coolant tank was bubbling away and spitting out fluid .After some reading I came to the conclusion I have air in the system so I would bleed the coolant system however when I went to do this I have no bleed hose {photo attached }

What would be the best way to install a bleed hose or is there another way round it ?
Part 3
So today I went to check the glow plug with a multi meter just to be 100% they are working and found this {photo attached }
