If coolant continues to seep from this area even after you complete the work as listed above, then possibility it could be your head gasket weeping coolant. If you renew your head gasket, do it right. Take the head for machining, do the oil rail to the stronger version + Hylomar sealant on new head gasket. Here's a link to my project, my 1.8 Freelander runs quieter than ever before and no more coolant loss or leaks. 1.8K Freelander Head Gasket Renewal and Overheating Fix - YouTube
