Looks like my 1.0 prefacelift Micra has come to the end of the road. In the last week it's been losing coolant for about a week checked all the hoses and thermostat spent a fair bit of time underneath it looking for a leak and found nothing, heater matrix is ok. Bit more white smoke coming out the exhaust though. So today I did a coolant co2 sniffer test. Went from blue to green within about 10minutes. Strange thing is it's not overheating and doesn't seem to be losing any power.Eventually I did find a very small hole where the clip sits at the top of the bottom hose( couldn't see it as underneath). Replaced the hose.
I am thinking about trying to sort this myself as prefacelifts are rare these days. I'm guessing garage would charge a lot to do this especially if the head needs machining. £500 at least...Had a quick look online and head gasket kit with all the bits needed is about £70-80. Weekend job 10hrs at least. Maybe cheaper to put another engine In? Bit of an unknown until cylinder head comes off and is there is any warping. Had a read of the Haynes manual and looks a long job. Been a long time since I've done a head gasket. Does the engine block on these warp? Or is it just the cylinder head usually. Done a few head gaskets on minis back in the day but these micras look a bit more involved. Not much room at the back either to take out manifold/ throttle body.Any advice greatly appreciated marco
