Hi - I'm a newbie that as just joined. A bit checky but I'm after a bit of advice.
I have a 2001 Mark I Kia Sedona 2.9TDi S diesel model that as done 105,000 miles.
I'm experiencing coolant lose through the expansion tank, which in turn causes the temperature gauge to rise to the hot level.
This problem is progressivly getting worse.
This history is that I had a new water pump fitted approximately 2 years ago (approx. 9,000 miles ago) when I had the timing belt replaced.
New radiator about a year ago. Originally noticed that the temperature gauge would rise from normal reading position (approx. 1/3 on the gauge), then suddenly shot up to 2/3rd reading and then drop back to normal. Daughter borrowed car and done a 200 mile run in it when the radiator give way. That was when the new radiator had to be fitted (12 months ago by qualified mechanic).
From that point car as been running great until about 6 weeks ago. Done a 60 mile run, most of it motorway, then went into normal town traffic when I notice the temperature gauge rise from normal to about 2/3rds. Parked up and noticed slight bubbling in expansion tank. Let the car cool down and done the return journey with no problems. Then 4 weeks ago, done a 150 mile motorway run. Temperature rose to the hot position. Pulled over and coolant in the expansion tank as bubbling hot with steam and hot water coming out the open release pipe on the expansion tank. Let the car cool down and, topped up coolant and got home OK (approx. 40 miles). Spoke to my nephew on phone, who is a qualified Luxus/Toyota mechanic, and his thoughts were that it's the head gasket gone. He explained that pressure may be coming from a compression chamber into the coolant system and blowing back through the expansion tank. Made enquiries at local Kia main dealer regarding cylinder head gasket parts, and the helpful parts guy suggested that I got a compressed air head cylinder test done. Main dealer did not offer this service, so ended up at a non-mainler garage who I was advised could do the test. I let myself get pulled over here, because I knew the proprietor of the garage. He said they had a look, removed the thermostat completely, done a 'lick test' and suggested he allowed me to put K-seal into the coolant system as a remedy. He did say that there is rusty particals in the coolant system and did say something was going on in the system, but could not state if it was the cylinder head gasket.
Done a 40 mile airport run last week, temperature gauge did not move from cold until journey end, then went up to the 1/3 mark. A week later on return from holiday, topped the coolant up with 2 litres of water and done the return 40 mile journey. Again, temperature guage did not move from cold until we got nearly home, where it rose to the 1/3 mark before suddenly moving up to the hot mark. Left car overnight and had to put another 2 litres of water to top up this morning. Used car this morning, only done a 5 mile run, checked the coolant and saw a steady stream of water flowing out of the expansion tank.
Whilst all these dramas have been going on, there is no evidence of oil and water contamination. The water looks clean apart from some very fine brown fibres both under the filler cap and what is in the expansion tank. Not sure if this is stuff from the K-seal or rust particles. Again, looking at the oil via the filler cap, there is no evidence of contamination. Also the engine still pulls like a train, with no apparent power loss or mis-fire.
Searched the web earlier and whilst looking at a Rover forum, a similar post was present and inlet manifold gasket was mentioned.
I know this post is a bit chapter and verse, but I'm wondering if anybody else as had a similar problem and been able to resolve. I want to have a go at fixing myself, because the car does not a great value to warrant putting into a main dealer for repair.
Many thanks for any forth coming advice.
