Changed my coolant after an unfortunate overheating incident during inspection, and am having trouble getting air out of the system.
I’ve tried letting the coolant expand into a funnel jammed into the rad fill port, with the car on a loading ramp with the front jacked up. No joy.
I’ve also tried applying negative and positive pressure with a 150NT “drain buster” vacuum pump (“WORLDS MOST POWERFUL PLUNGER” Ooer Mrs).
That didn’t work either.
Another Internyet recommendation is to try and vent air via the heater matrix connections. Didn’t try this earlier because I thought they would be rather inaccessible.
Just had a look and…er…the heater hoses to the matrix are indeed not very accessible, because there don’t seem to be any.
Just call me Master of Understatement.
Or Blind As A Bat
COULD still be missing something, but the engine compartment is fairly spacious (In sharp contrast to god-awful modern cars I’ve looked at) so I don’t see how.
I assume heater functionality, if it has any, is done via the aircon, which isn’t AFAIK, connected to the cooling system.
Is this plausible? Never had an aircon equipped car in the UK so don’t know what the norm is.
AFAIK this is a Taiwan-only car so it COULD be local weirdness, but I’d be surprised if they deviated greatly from general Daihatsu design norms.
