På av de viktigaste saker att göra med en Rover / MG / Freelander K-serien motor är att regelbundet kontrollera vattnet – ett problem upptäcks tidigt kan spara mycket pengar! Så du har regelbundet kontrollera din vattennivån och allt har gått bra, tills en dag du kontrollera det och det har använt mer än normalt. Vad kan det vara?
Om alla andra förhållanden är som vanligt – det är du inte arbetar det svårare än vanligt så det kan naturligtvis ha använt mer vatten – då det finns ett fåtal platser där vattnet kunde fly från:
- Det kan vara din topplockspackning. Om så är fallet kan du se en läcka runt topplocket, men vattnet kan flyr in i oljan – detta skulle dyka upp som en majonnäs färgade rest inom olja, ofta sett på oljetanklocket tank.
- Kan det vara att ditt vatten pump försedd med eller läcka igenom en sliten tätning. I denna situation skulle du brukar hitta att det droppar när bilen har drivits. På en Rover / MG / Freelander K-serien motor droppa skulle ses på sidan drivrutiner på framsidan av motorn; på den Rover / MG / Freelander K V6 motor droppa skulle ses på sidan drivrutiner på baksidan av motorn.
- Din termostat bostäder kan vara knäckt eller ha slitna tätningar. Om vatten fly från termostat huset du förväntar dig att se vattnet droppa från baksidan av motorn under inloppet grenröret för en Rover / MG / Freelander K-serien motor. Med den Rover / MG / Freelander K V6 motor termostat huset ligger i centrum av V så att vattnet skulle rinna in i V och sedan kan droppa ut på baksidan av motorn. Med K V6 motorn kan det vara svårt att avgöra varifrån DROPP är om det är termostaten bostäder eller vattenpumpen.
- Läckan kan vara från kylaren, därav det skulle droppande från, ja, kylaren!
- Kylning system rören kan försvagas, orsakar dem till split eller klipp håller rören har lossnat och är inte längre stark nog att hålla trycket på vattnet som det expanderar. I någon av dessa situationer är det ett fall av kontroll för DROPP från någon av kylning system rören i motorrummet.
- Det kan finnas en läcka i din värmare matris. Generellt om din värmare matris läcker hittar du foten väl inne i bilen blir fuktig.
- Läckan kan komma från din inlopp insugningsrör packning. Kontrollera vatten droppande från runt öppningen Samlingsröret.
- I en Freelander kan vatten läcka in IRD om kyla plattan har skadats. När paus slangen på IRD enheten – om detta är fallet då du inte ser ett dropp vatten som läckan är inre till IRD enhet.
- Kanske är den värsta orsaken till en vattenläcka en spricka i en av cylinderfoder. I denna situation skulle läcker ut vatten i själva motorn. Ofta endast små mängder vatten flyr in i motorn vilket kan innebära att spår av vatten i oljan inte är uppenbara.
För effektiv kylning av Rover / MG / Freelander K-serien motor kräver röd kylarvätska som skall användas, och när det gäller att fastställa var en läcka är detta ofta kan vara mycket fördelaktigt som om läckan är drypande externt det lämnar rosa fläckar runt området av DROPP.
Men don ’ t panik, vi kan hjälpa!
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,
Sue

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.
All the best,

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,
Sue

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.
