Ek is nie oortuig dat 'n 'hose-pipe" toets die blokkasie in die verkoeler reg sal uitwys nie. Die water vloei dalk steeds teen 'n redelike tempo deur die verkoeler, maar dis dalk steeds te min EN dit vloei dalk net deur een gedeelte van die "core" omdat die ander gedeelte geblok is. Haal die verkoeler uit en laat spoel hom behoorlik by Silverton. Die kanale kalk toe, soortgelyk as 'n elektriese ketel. Dis net 'n behoorlike suur behandeling wat dit weer skoon maak.

Maniak the best way to clean a radiator is to take off the tanks. It is then easy to see if any passages are blocked. The blocked passages are cleaned by pushing a steel rod through. Thereafter it is acid cleaned and then the radiator is re-assembled. As JG says this is a job for Silverton or somebody similar.

Thanx gents for the feedback.
I have been told by CHE that it is an alu radiator, so they can not chemically clean it, and that they can do a flow test, but that the "hosepipe" test I did would give a clear enough indication.

The search continues. Waiting for the thermostat and will then open up and see.

remove the radiator.
Remove top & bottom tanks
Obtain strong gut or fishing line or twine [moet sterk wees]
dip 15mm of one end in hot wax and allow to set [nou het jy so 'n harde puntjie.]
measure the depth of the core channel [with a TAPE MEASURE on the outside] Now cut your "line" but add about 50% to the core depth.
Beg, buy or borrow [DON'T steal] a brass rifle cleaner brush [7mm rifling should be O K, must be a tight fit] (NO pun there!)
Place radiator core on suitable surface.
Drop said line/twine/ through and pull on the end that comes out until the rifle brush is through]
Repeat for each channel.
Now you know the rad is clean inside, re-assemble, replace.
Remove water pump - check for corrosion and wear - [IF the impeller blades are warn out, the pump sucks more water than can get through the system and that would result in the hose being sucked in [because their is no air present inside the system, the normal atmospheric pressure from the outside will "press in" the hose - to compensate for the vacuum]
Replace impeller blades or entire pump.
If above does not solve the problem, take "bloudraad", form into a coil same size as inside diameter of that sucking pipe, work this into said sucking pipe [do NOT change my spelling here :-)] - The cause will not be fixed but the symptom is now cured

STERKTE - Good luck

Baie dankie almal ... oom Mac ek het so loop borsel stelletjie, so gaan hom probeer.

Strange and funny....Silverton removes the top- and bottom plastic tanks and does clean the core chemically.
