Sloshing coolant in heater matrix

As title says really am having a real problem with sloshing water in the heater matrix on my 2000 1.8 k series freelander i will tell you whats been done so far

i have just replace the headgasket (i have done loads on the k series engines) i have replaced thermo stat, temp sensors, coolant cap, heater matrix and have bleed it alot of times and also drained coolant and refilled it and bleed it again but still seems to have sloshing water but she never seems to over heat and the rad fans kick in as they should and the sloshing water noise also seems to go when the car reachs normal temp. o and i have also replaced water pump.

so am abit stuck on what to do to get rid of the noise

cheers

Are the heater hoses routed correctly and was it a genuine matrix or pattern?

yeh mate look to be correct and its oe looks like it had a replacement oe matrix before i bought it as spares but the had the same problem of sloshing water thats why i replaced it thinking it was this but maybe its something else causing an air lock

Not still got gunk in the upper heater hose have you from the head gasket failure?

If it was blocking the top 5mm or so of the hose it would never bleed up quite right!

Just read this thread - I am having the same issue on my 1998 S reg K series - I will disconnect the hose and check as I know the previous owner changed head gasket about 2 years ago and I get a gurgling in the car every morning.

Change the rad cap and keep a close watch on your coolant level, try and get a sniff test on your coolant

Revisting this as i am not have anylook still got the annoying noise i have cleaned pipes and cooling system best i can i am going to replace thermo stat again and o rings on the housing along with inlet manifold gasket

i have replaced expansion cap and she runs fine and doesn't over heat and all pipes are getting warm and heater is working but it is just annoy

anyone had this problem and solved it?

Are your hoses the correct way around? The one with the bleed screw in should be at the top going into the firewall?

Yeh mate they the correct way

can that bleed nut be unscrewed?

Is it water in the 4 inch pipe to the rhs of the matrix box, hitting the fan to the rhs?

Not sure really you can only hear the noise inside the car

If you pull the 4 inch pipe oft you can put yer hand in (with fan electric oft) and feel for water in the pipe, electric fan housing or air filter housing. Worth a go.

Hang on, have you not bled the pipe up using that bleed screw on the top hose? ... if not that's your problem right there.

I will give that a try hippo

And i have bled it from the bleed nut on the metal coolant rail which is connected to the thermo stat housing

Yes, but you also have to bleed it from the hose that goes into the heater matrix?

Well i never new that haha i wil give that ago cheers mate

Yeah, undo both, blow through the overflow hose to dislodge ball bearing (its the hose coming from near inectors and timing cover up to the coolant bottle hose) fill her up till the lower one starts spouting and seal it off. Then keep filling till the top one does the same and runs free of bubbles before sealing that one off as well.

Mine was properly bled but my water pump had died so i got the sloshy noises until my head gasket blew. Might be worth checking the water pump is okay if you're already rebleeding it.

Hi Saul, how did you go? I have a 1.8 Freelander like yours, mines Feb 2000 so it's the distributor engines from 1998-2000, not the latter glow plug ones. I had this problem like you describe now occurring and despite me bleeding the system, it would still continue to re-occur. The problem with mine was a tiny very tiny amount of coolant that was weeping from the head gasket and leaking externally. The location was the front right, right at that corner next to the Air. co. compressor. It was extremely hard to spot as the tiny amount would burn off from hot exhaust parts. This would continue to introduce air in to the system and no matter how much you bleed it, air would somehow find it';s way in to the heater and I'd hear that gurgling sound each time I started the engine. I meant to ask you, when you renewed the head gasket, did you at all turn the crankshaft with the cylinder head removed? If so, in the process, you can not only dislodge the liners as they are wet liners, but (more importantly), you can impact the liner seals. These are the sensitive seals at the wet liners that keep the coolant around the liners in the water jackets and out of the engine. If one of your liners is leaking, this can be extremely difficult to diagnose as the tiny leak means it can sometimes only leak very minute amounts, not even enough to generate white smoke out of your exhaust, and only leak very minute amounts of coolant and when under the greatest pressure thus when engine working hard and at temperature. Thus, if you pressure test your cooling system when cold, it may not necessarily show.

Thanks for the replys guys i wil try bleeding the system how its been suggested hope it aint water pump as i changed that along with headgasket

but nope i always time the engine up with the head on so that the piston liners don't move but hopefully am getting the noise cause i haven't bled it quite right but i appreciate the replys

Hope it isn't a Britpart water pump....
