streamline Posted January 29, 2008 Share Posted January 29, 2008 For some months I have found I have had to top up header tank, which is unusual. Last Friday I find a large wet patch under the vehicle and on investigation there was water on the front left hand corner at the bottom of the block and lip of the sump. This I found strange as I had replaced the water pump gasket not long since for the second time. (This being a well known fault) Nothing for it, get stuck in, on removing the fan I found water laying in the fan cowling and this had not been there on previos occaisions. A liitle more investigation was indicated. Topping it up and running the engine, water appeared from the plastic plug on top of the thermostat housing. The O ring HOOray. Regettably not. On undoing the plug with a spanner the top of the plug parted company with the bottom and it was obvious that it had been fractured for some time, That will teach me not to over tighten plastic, Remove T/stat to aviod damage-- ream out plastic with fie tang-- cut through plastic with pad saw in 4 places on plug circumference avoiding cutting into threads-- carefully chip out plastic between cuts-- clean up housing threads( a 15mm compression stop end turned out to be the right thread) Insert new plug not overtightening it . Hope some one fins this help ful Quote Link to comment Share on other sites More sharing options...
