På de mest vigtige ting at gøre med en Rover / MG / Freelander K-Series motor er regelmæssigt kontrollere vandet – et problem, der er fanget tidligt kunne spare dig for en masse penge! Så du har været regelmæssigt at kontrollere din vandstand og alle er gået godt, indtil en dag du tjekker det, og det har brugt mere end normalt. Hvad kunne det være?
Hvis alle andre kørselsforhold er så normal – er du ikke har arbejdet det sværere end normalt så det kan naturligvis have brugt mere vand – så der er et par steder, hvor vandet kunne flygter fra:
- Det kunne være din toppakning. Hvis dette er tilfældet, kan du se en lækage omkring topstykke, men vandet kan flygter ind i olie – dette ville vise sig som en mayonnaise farvede rester inden for olie, ofte ses på olie tank fyldstof cap.
- Det kan være, at din vandpumpe utæt gennem en slidt seal eller forsynet med. I denne situation vil du har tendens til at finde, at det drypper når bilen har været kørt. På en Rover / MG / Freelander K-Series motor drop ville blive set på drivere side på forsiden af motoren; på den Rover / MG / Freelander K V6 motor drop ville blive set på drivere side bag på motoren.
- Din termostat boliger kan være revnet eller har slidt sæler. Hvis vand er flygter fra termostat huset du ville forvente at se vandet drypper fra bagsiden af motoren nedenunder indsugningssystemet for en Rover / MG / Freelander K-Series motor. Med den Rover / MG / Freelander K V6 motor termostat huset ligger i centrum af V så vandet ville dryppe i V og derefter kan dryppe ud på bagsiden af motoren. Det kan være svært at fortælle fra hvor drypper er, om det er termostaten boliger eller vandpumpe i med K V6 motor.
- Lækagen kan være fra radiatoren, derfor det ville være dryp fra, godt, radiatoren!
- Kølerør system kan blive svækket, forårsager dem til split eller clips holder rørene har løsnet og er ikke stærk nok til at holde trykket af vandet, da det udvider. I en af disse situationer er det et tilfælde af kontrol for drypper fra nogen af system kølerør i motorrummet.
- Der kan være en utæthed i din vandvarmer matrix. Generelt hvis din vandvarmer matrix er utæt vil du finde foden godt inde i bilen bliver fugtig.
- Lækagen kan komme fra din inlet manifold pakning. Check for vand dryp fra omkring indsugningssystemet.
- I en Freelander kunne vand lækker i IRD hvis afkøling pladen er blevet beskadiget. Kontrollere Åndehuller slange for IRD enhed – hvis det er tilfældet så vil du ikke se et drop af vand som lækagen er internt i IRD enhed.
- Måske er den værste årsag til en vandlækage en revne i et af cylinderforingerne. I denne situation ville utæt vand ind i selve motoren. Ofte kun små mængder af vand flygter ind i motoren, hvilket kan betyde, at spor af vand i olie ikke er indlysende.
For effektiv køling af Rover / MG / Freelander K-series motor kræver den røde kølervæske skal anvendes, og når det kommer til at afgøre, hvor en lækage er dette kan ofte være meget gavnligt som om lækagen dryppende eksternt vil det efterlade lyserøde pletter rundt om drop.
Men don ’ t panik, vi kan hjælpe!
Hi I have a 2003 mg zt 1.8 turbo with 102000 miles on. 2 years ago it had the triple layer head gasket upgrade so I’m a little stumped by my latest fault? When the car has been stood and gone cold and I start it up I get quite a lot of white smoke which stops once it has started to build up temp. Any help with this would be taken onboard with many thanks Wayne
Hi Wayne,
Apologies for the delay in responding.
This sounds very much like an issue with your cylinder liners. If your MG overheated previously it could be that they were compromised then and are only now showing the signs.
All the best,

have a 2002 1.8 freelander , straight through mot the other day coming back started to get hot lot of pressure in the hoses and header tank, it has a new tank and replacement thermostat on the front of engine , no smoke or water leek apart from boiling up in tank, fine on tick over just when going up hill gets hot could this still be head gasket or something else
Hi I have rover 75 2.5lt v6 24v and the temperature gauge keeps going up and down I have noticed a drip of water under drives seat but theres no white scum. Under oil cap nor can I see any water in the header tank is the rover dead?
Hi Peter,
Apologies for the delay in responding, somehow your comment slipped through the net.
This does sound like a head gasket issue with exhaust gases going into the cooling system unfortunately.
All the best,

Hi Scott,
Is the drip by the driver’s seat happening inside the car? If so then you should check if the heater matrix is leaking.
If there is no coolant in the header tank then fill it up to the maximum and keep a close eye on it.
Have you checked for signs of a leak in the V of the engine? If it is leaking there then it will be the thermostat housing, which is a fairly common issue as they are plastic housings positioned in the hottest part of the engine. We do have a modification for this in terms of a metal thermostat housing and pipes – not cheap but a much better solution.
All the best,

Hi.
i have been following the thread with regards to the rover 75 2.5l v6. Iv got a leaking thermostat housing i do not want to replace it with another plastic unit.
I saw somebody mentioned a better unit thats available how would i be able to get my hands on a unit and what is the pricing.
Im in south africa cape town.
If anyone has any information please contact me. Laeeqolivergti@gmail.com
Im not sure if this is a local forum.
Hi Laeeq,
We can supply you with the metal thermostat kit which includes the metal thermostat housing and the associated pipes. We are based in the UK. The kit is £245.83 and shipping to South Africa is £45 by courier.
All the best,

Hi guys, fairly new to owning a car so bear with me. Recently I bought a 2003 mg ZT+, when I did my checks the coolant seemed empty and the oil too so I topped them both up. Got the car insured this Friday just gone so naturally I was driving all day to get used to it. Later I noticed the fan was coming on a lot and when I popped the bonnet to get a bit of air to it I noticed a little smoke, nothing major. On the way home the engine overheated and the temp gauge was at maximum. When I checked the coolant the bottle was empty. Waited till next morning and topped up the coolant again, but when I looked under the car it looked like coolant was leaking fromwhat looks like the sump. I’ve checked the oil and all seems fine, no build up no residue. Had it to 2 garages and I’ve been told it’s head gasket failure by one and heater matrix by another. The footwells not wet though. I’m thinking airlock but not sure, please help!!!
Hi Chris,
If the leak is external, i.e. you can see that coolant is coming out then it is most likely a leak from the water pump or the thermostat housing. It is possible for the head gasket to leak externally but it is more common for it to cross contaminate into the oil. Sine you can see coolant leaking check the water pump and thermostat, if you have red coolant in the system (which is the coolant you should use) then you should be able to see the pink residue around where it leaks. If you are having difficulty then it could be worth doing a pressure test on the cooling system.
All the best,
Sue

Colleagues,
I have numerous leaking & overheating problems with my Freelander K – Series, 16 V , Petrol. The best medicine , that I believe will save me time, money and ‘ stress’ , is to’ down the engine ‘ , then just re- build the engine.
Yes ! Sounds strange to some, but once these engines go around 100 000 miles, leaks,overheating head gasket issues/ problems are inevitable.
I am re- building mine & have bought the re- built kit components … almost all in place save for the Head Bolt set and Cam belt tensioner. This will enable me to inspect all the internal components & replace them if need be.
Hope to share the results after engine re- built. Thanks for sharing the possible causes of water loss.
I love my Freelander ! It shall be well !
4×4 by FAR ! 🙂

Hi Mr Q.
We look forward to hearing how you get on with your engine rebuild. The Freelanders are certainly great vehicles.

I seem to have a lot of coolant being omitted from the exhaust. I ve changed the inlet manifold gasket. It s had new top and bottom hoses and a brand new radiator because the old ones were shot. The oil and water have not mixed together and it doesn’t t overheat
Would the excess coolant from exhaust be the headgasket on it s way out? Thanks
Hi i hv a rover 75 V6 . Did change the thermostat housing as it was leaking. Now when i fill the radiator and drive with the car it looks like the cooling system build up pressure even when the car is cold in the morning and i open the cap the water push out of the radiator can anyone tell me what can be wrong
Hi Johan,
Did you bleed the cooling system when you changed the thermostat? Is the bottom radiator hose getting hot when the car is up to normal operating temperature? Are the fans coming on when they should?
All the best,

Hello T.Martin,
It sounds like your cylinder liners may have dropped or cracked if it is the 1.8 K-series engine.
All the best,
Sue
Hi hope you can help. I have a non turbo 1.8 MG ZT and it uses or loses a litre of water. No sign of visible leaks no steam from exhaust or oil scum red coolant just disappears. No engine error codes had recent water pump when cam belt wad done and inlet manifold gasket is replaced. I have checked hose connections am totally perplexed.
