Flushing Chemiweld and Gunk

Howdy
It would seem that my radiator is quite blocked with gunk from the new second hand motor and some of the chemiweld that was left in my radiator from the original motor.
I am gonna try and flush it myself before I give someone $200 to do it, what is a good solvent to use?
I hear about a litre of diesel in the cooling system, running for about half an hour will work wonders and then allow me to hook the pressure sprayer up to the rear heater hose and pull off the top radiator hose allowing all the gunk and chemiweld to fuck off.
Anyideas on this method? Improvements maybe?

I think you'll find that radiator hoses aren't very tolerant to fuel.
Take the radiator out, give it to someone, and get it cleaned.
It only costs $90

Arghh... what is with everyone wanting to stick diesel in their water / oil system today?
Chuck in some Tecaloy Radiator Flush or similar and drive around for a few hours (i.e. follow instructions on bottle).
If that doesn't de-gunk things drain your coolant and then remove your thermostat... put everything back together sans-thermostat. remove the top radiator hose from the radiator and then stuff ye-old garden hose in the hose... turn on the hose and let it rip for a bit.
If you took your car for a reverse flush they would do pretty much as above but they would use an air compressor to give the water a bit more pressure.

what he said ^... except, if you can use the firehose at work insteaad of the carden hose, it'll help flush a system (with no thermostat inside).
Just be careful NOT to point nozzle directly at the radiator...

cheers for that fellas, will the CHEMIWELD have permenatly gunked up my radiator??
I might have a go at cleaning and flushing it myself i reckon, it all they use is a wirebrush and elbow grease and the bottle like cleaning things.
Once again thanks for teh help

MAN I DID THE SAME MYSELF ON THE WEEKEND , CHANGING COOLANT AND THERMOSTAT --
now my car runs fine and warms up heaps faster 6 min i think compared to 14 lollll nand also the tranny goes into overdrive and no fucking rpm jumping up and down
i drained the system first then used plain water and run the heater on full blast run for around 20min with cap off u will see bubbles or froth then drain again , repeat proceduere , then buy some tecaloy mukout its a yellow coloured fluid put in radiator refill again go for drive or wait for 30-40 min , better to drive around for like 20 min , then drain again
remove top radiator hose from engine take radiator cap odff then stick garden hose into radiator and full blast until u see clear water coming out of the engine ( take thermostat out in the start), then drain again and refill with toyota red coolant 38 dollars for the bottle mix with some distilled water 1 liter each should do the trick 
all should be well after 
also refitted a new power steering cooler (pita) to do , factory power steering cooler is gone now and replaced with a ford tanny cooler and now resides behinnd the griffin on the grille (soarer gz20), took me a lot of time and effort to with a lot of bruises fcuking coolers oil cooletr 22 and hose30 dollars 50 bucks all up 
the stuff that came out from the power steering was black fluid now has nice red type3 dex atf in it steering feels a little harder though (maybe im imagining it though ) 
be prepared to have u lawn grass turned to brownish black if ur doing the flush in the backyard and the garage to be filled with oil allover if u doing the power steering cooler , oil fcuking went everywhere when hose was disc and dripped all over the floor 
oh also clothes and shoes drenched in oil and a lot of bruises and scalding from te coolant due to squuzing the radiator hose without radiator cap on  
cheers

5 mins... man it takes alot longer than that! but if it wasnt HOT, and you put it in SLOWLY, you can get away with it tho its still not advised, especially if the engine has an alloy head.

if you cracked the head you would probably know by now, take your car for a trhash up the freeway and see if it overheats, if it does then check your oil for milkyness.
Thats all i can offer sorry
Also as if you didnt know the soarer had an alloy head, how many japanese motors do you know of post 85 that dont have alloyheads?

I was there the whole time
they used some industrial coolant, came out of a 44Gallon drum with holden written across the side but the dude says he uses it in all his cars and he has never had a problem and he drives a JZA80 TT, so it must be ok

yeah man, he pulled off the rear heater hose, stuck a high pressure cleaner into it with some funky attachment and attached a high pressure air gun into the back of the hose where the the water was, made sure the bottom radiator hose was off, which is was because the radiator was out anyway and then fired up the water and gave bursts of air every now and then, this went on for about ten minutes untill it was deemed clean then it was all put back together
