  1. Doing my head in this one, had the rad fluid changed and check level at header tank every day. The heater will kick in after a while but just seems off to me also had another thermostat put in so very sure not that. Keep asking the mechanic about air locks and fluid levels and he is positive no air locks. I have felt the hoses the push water to the heating matrix and the are quite hot so sure that water is flowing.
  2. how hot should it get in the cabin, N reg 300tdi? Just had loads of work done and this is the first time using heater but does not seem to kick out much, takes ages to get warm but even on mid point on the gauge its still not that hot, normal?
  3. I am so paranoid about my cooling system after getting a new head that I have been checking the fluid level berfore and after every trip. I have notices what looks to be what I describe as swamp gas lingering over the water in the expansion tank, what is it? Its a new head so cant be exhause gases, had a sniff and could not detect anything so any ideas?
  4. It has a 300tdi engine. before and after most trips I check the water level, never seems to be low. Can it be low but still indicate normal in the expansion tank? Also, how do you know if there is air in the system? I was getting the guggles in the heater which I now know was air. Is there an easy way to bleed air? Each time it has overheated it has been sudden. I have had the gurgles for a long time but never userstood what that was, could there have been a long term air lock that was causing the head to go or was it the head causing the air in the system? Got it back the weekend and the mechanic swear he has gone through the entire system and notihing. Gave it another flush to ensure rad and system clear, water is looking nice and clean now so no carp floating through. Still puzzeled, since the first over heating I check fluid level almost every trip and have never seen it low thats why I dont understand. Next to last time I checked the fluid before I started and it was perfect, pulled out and drove 5 min then it overheated and Mildly miffed all the fluid out the expansion cap.
  5. After long trip did not need coolant, checked next morning. Also, did run the heater and have noticed a gugling sound. I pointed this out to the local LR guy but he says heating system is fine.
  6. Not sure about first head and bolts but he did say put new bolts on this time because felt the old ones had streached.
  7. I lost my first head when a hose split and dumped the contents, all sorted new hoses and new head. Since then I have had three strange over heating incidents, last one fatal (another head). My local LR man seem the business but can not find the cause of my three incidents. It has been back to him a few times, had it a week once but nothing showed up and he drove it every day. He has flushed the cooling system several times and put some stuff in to clean the system out, again several times. He put on a new thermostat and re checked every hose for leeks, none. There seems to be talk of some type type of air lock causing the problem. I did get a gurgling noise at the drivers foot well which I now guess is air gurgling around. On two ocasions the engine ran a very long time, once to wales and once to the lake district with not heat issue showing. Next morning after checking water level the engine overheated withing minutes of starting. Strange also that headting did not work just prior to the overheating. After each incident I let the engine cool down, took off the expansion tank cap (was under preasure) and filled with water. After that the engine ran fine again, back from wales and lake district. Last incident same thing, all the way to wales fine and next day over heated first thing in the morning except this time total death and time for a new head. So, what is going on? As stated my LR guy is very good with 30 years of pure LR experiance and he has ripped the carp out of the thing and says can find not one thing wrong. I need some fresh ideas because I can not afford to keep being recovered from all over the UK and heads are very expensive every 6mo.
