KV6 freelander_ possible radiator??

ok long day, my freelander has confused me so much....!

Ive re-replaced the stat, and flushed the complete motor/pipes/rad/cooling units etc. new waterpump, and a while back added a used radiator. now the car runs nice. Though it has no heat, or extremly low heat...and eventually overheats..... I've bleed it like crazy.....

What i've noticed is the expan/tank seem to be flowing normmaly, while hot, (norm temp) i've noted certain instances on idal the coolant flucuates into the expand tank, then lowers slowly and flucuates again, and if i loosen the cap its began to flucuate all the way.... i cant tell for sure but it seems that the coolant cirualtes oddly.weridly... ?

Im thinking the radiator, oh and when i cut the car off, the radiator makes werid nosies, like the sound of cracking plastic or sumthin,(hence nothings cracking.lol) I've also noticed the upper raditor hose seems to clucth itself as if only sections at a time is rapidly going through the raditor or expand/tank.........?

id say your head gasket has gone. time to have gead removed....

You need to carry out a sniff test to eliminate the HG's

welll the thing is the spark plugs all check out fine, no oil or coolant is mixing, either... how would i know if it was the radiator, i assume the systoms of the radiator are normal? thankyou peeps.lol

head gaskets can go in many many diffenent ways. sniff test only tests for one of them ways

what do u mean "sniff test" and based on the above radiator systoms, u think are norm? thanks

I know you've bled it a lot already but it does sound like either an airlock or some other circulation problem.
Did you use Radweld on it before you changed the radiator? If so it could have caused a blockage elsewhere.
Why did you fit a used radiator? I got one on eBay for £66.
If it has overheated you should get a sniff test as Nodge pointed out.

Re: sniff test, info here

No i havent used that radweld, stuff,but whats a sniff test? :/

See the link in my post above

ok thanks for the link, i'll have to check it out...

There are lots of different ways to ascertain weather a HG has started to fail. A sniff test is only 1 but it's a good indication that combustion products are entering the coolant. A leak down test it also useful. The K range of engines won't tolerate any kind of air in the cooling system!! The lightweight construction can't take localized overheating so it's important that all or almost all the air is removed from the cooling system before the engine is fired up. When the cars were built the cooling system was vacuum purged of air before the engine was started.
