De coisas mais importantes para fazer com um Rover / MG / Freelander K-série do motor é verificar a água regularmente – um problema detectado cedo poderia economizar muito dinheiro! Então você têm sido regularmente verificar seu nível de água e tudo tem corrido bem, até que um dia você verificar e ele tem usado mais do que o normal. O que poderia ser?
Se todas as outras condições de condução são normalmente – é que você não está trabalhando é mais difícil do que o habitual assim que naturalmente pode ter usado mais água – em seguida, há alguns lugares onde a água poderia ser escapar da:
- Pode ser a junta do cabeçote. Se for esse o caso você pode ver um vazamento ao redor da cabeça de cilindro, no entanto, a água pode estar a fugir para o petróleo – isso apareceria como um resíduo colorido maionese dentro do óleo, muitas vezes visto na tampa de enchimento do tanque de óleo.
- Pode ser que sua água bomba vazando através de um selo desgastado ou rolamento. Nesta situação você tendem a achar que ele pinga depois que o carro tem sido impulsionado. Anna Rover / MG / Freelander K-série do motor o gotejamento seria visto do lado de motoristas na parte dianteira do motor; sobre o Rover / MG / Freelander K V6 motor o gotejamento seria visto do lado de motoristas na parte de trás do motor.
- Sua carcaça termostato pode ser quebrada ou ter usado os selos. Se a água é escapar da caixa do termostato você esperaria ver a água gotejamento da parte de trás do motor debaixo do colector de admissão para uma Rover / MG / Freelander K-série do motor. Com o Rover / MG / Freelander K V6 motor a carcaça do termostato está situado no centro do V... então a água que escorra até o V e então pode pingar para fora na parte traseira do motor. Com o motor V6 de K pode ser difícil dizer de onde o gotejamento é seja a carcaça do termostato ou a bomba de água.
- O vazamento poderia ser do radiador, portanto, iria ser pingando de, bem, o radiador!
- Os tubos de sistema refrigerando poderiam ser enfraquecidos, levando-os para split, ou os grampos segurando os tubos afrouxaram e já não são fortes o suficiente para segurar a pressão da água, como ele se expande. Em qualquer dessas situações, é um caso de verificação de gotas de qualquer um dos tubos de sistema de refrigeração no compartimento de motor.
- Pode haver um vazamento em sua matriz de aquecedor. Geralmente se sua matriz de aquecedor está vazando você encontrará que o pé bem dentro do carro se torna úmido.
- O vazamento pode estar vindo de sua gaxeta do distribuidor de entrada. Verifique se há água escorrendo em torno do colector de admissão.
- Em um Freelander água poderia estar vazando para o IRD, se a placa de refrigeração foi danificada. Verifique a mangueira de respiro para a unidade IRD – se este for o caso, então você não verá um gotejamento de água, como o vazamento é interno à unidade IRD.
- Talvez a pior causa de um vazamento de água é uma rachadura em um dos forros do cilindro. Nesta situação água poderia estar vazando para o motor em si. Muitas vezes, apenas pequenas quantidades de água estão a fugir para o motor, que pode significar que os vestígios de água no óleo não são óbvios.
Para arrefecimento eficaz a Rover / MG / Freelander K-série do motor requer o refrigerante vermelho deve ser usado, e quando se trata de determinar onde um vazamento é isto muitas vezes pode ser muito benéfico como se o vazamento está pingando externamente deixará manchas rosa em torno da área do gotejamento.
Mas don ’ pânico t, podemos ajudar!
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.

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.

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,

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.
