[thebigyin]

2002 (52) plate KIA sedona 2.9 crdi L
just wondering if anyone has owned one or got some experience as i have one and it is running fine Ive had it about 6 months now but since i got it i have needed to put around 1 to 1 and a half litre of water in the coolant system every 2 to 3 weeks its concerning me as the KIA has no min or max for the water it goes into the radiator cap the min and max is only on the reserve water tank if it over heats etc which it has never done but just wondering if that is normal as not all cars has to full to the top with water any help would be great thanks.. i dont know if im doin the car any favours filling it to the top with water every 2 to 3 weeks

the temp gage stays fine never goes by half way,,there is no mixing with oil/water..Ive checked for leaks under the car i cant see any leaks etc..it starts first time and drives good no misfire or anything like that,its the topping it up with 1 to 1 and a half litre of water every 3 weeks that is worrying me..is this normal for the KIA sedona

Its not normal to have to keep putting water into a car on a 3 weekly cycle. Take the spare wheel off under the car and check for dampness on the 2 rear heater pipes. Do it after a run when the engine is hot and leave the engine running( have someone sat inside it to stop some scrote nicking it) then check underneath, Also check the drivers side front for leaks and check the carpet inside to see if its damp

Bruno told you . It's 99,9% that it's the rear heater pipes, as it's a common fault.

i noticed a leak today just under the drivers door its a steel pipe joined onto a rubber pipe do i need to buy the steel pipe to fix it or are they anything i can do to repair it like using gum gum paste or something like that
