Preassure in cooling system

[tomipav]

Hi
I changed my water radiator on agrotron 106 few months ago,it probably aint original.
Now when working the preassure in cooling system is to high,the water in when working goes out under preassure mosty in places where water hose is attached to radiator or water tank.
What cold cause this?
Cylinder head is repaired few months ago also.
A friend says that the replacment water radiator could case the problems,that water has to small flow trough the radiator?
Any tips?

Head gasket? Common on green and yellow ones. Exhaust gases pressurise the coolant

Head not torqued down enough/correctly? Head bolts reused?

Have some one do a gas test on the coolant to rule out a cracked head or blown head gasket......................................

Bolts were reused,in that i'm sure,i was in the workshop when they were returning old bolts,now i dont know did they tourqed them down correctly/enough that i'm not sure. I assume they know what are they doing.
Should i tourqe them down again,maybe the got lose?

No experience of deutz. But some need retorquing after a few hours. You need a manual.

Was head skimmed?

Have you checked what pressure it's running at.also check the cap it should have pressure relief in it.is it blowing out or building too much pressure.even if the head is gone it should not build too much pressure just blow it out the overflow

@startinghandle,yes it was.
@rob h yea i thought of cap,and bought a brand new one,and that is an interesting part,the preassure sholud go out trough the relief in the cap,wright?
But for some reason it goes out where the hose is attached with clamping ring.
I havent checke what is the preassure,didnt had time,but i will.
Oh yea,and engine is not overheating,it's on normal working temperature,water is not boiling in the tank.
