Creamy substance around coolant expansion tank


Recommended Posts

Hi I have recently purchased a freelander 1.8 on a 55plate, with 51,000 miles on the clock, my partner was looking at the coolant tank and noticed a creamy substance round the cap, does anyone have any ideas what it could be? I've only had the car for a week. Your advice would be greatly appreciated

I believe that coolant is slowly seeping from the head gasket due to lost torque of the original cylinder head bolts, this used to be a problem on some 1.8 Freelanders. It's difficult to see coolant disappear as it can simply burn off as it drips or flows down the exterior of the engine block while it runs. Overheating is usually another sign. In 2005, Land Rover released an uprated oil rail for the 1.8 Freelander which is stronger than the original (the head bolts screw in to the oil rail). So to do this job correctly, I would recommend you renew the head gasket + renew the oil rail to the uprated + use Hylomar sealant, 2 coats each, on each of the following (engine block facing, both sides shim, both sides new head gasket). I videoed this project, here it is. http://youtu.be/BbVNPNzcx6M
