People on here seem to prefer to carefully solder the rads rather than using radweld as it doesn't get pumped round the rest of the cooling system and through the block as radweld does. Reminds me i must go check mine, i noticed signs of a minute leak last weekend but didn't have time to do anything about it.

Solder it, get it repaired or re-new it.

If it's leaking, coolant will be lost under pressure as steam, and air will be sucked back in instead of coolant from the expansion tank when the engine cools.

No coolant= cracked head!

Mine had a slight leak for a while. Fixed it with liquid metal as a temp repair - so I thought.
When it give way I didn't realise until it was too late and I ended up needing a new head.

I would order a new rad and replace leaking one asap. While the rad is out flush the cooling system out thoroughly, replace rad cap & thermostat at the same time. When refilling the system take your time and search all the threads on here first for hints on avoiding / removing air locks.
Hope all is fine when done

roughtrax seem to have a good name for parts. http://www.toyotahilux.com/

It's removed from the top, but you'll need to remove the bashplate to get at the bottom hoses.
Don't forget to insert something into or clamp the ends of the transmission cooler hoses when you pull them off the rad or the fluid will be lost.

I bought a new rad from Roughtrax last tuesday and they are top quality.

The transmission fluid circulates through the bottom tank of the rad in a seperate tube.
Top tip: Get yourself some good quality hose clips as the originals don't clamp up as tight when re-fitted.
4 for the top and botton rad hoses, and 2 for the transmission cooler hoses.

replacing the rad is quite an easy job, i gave myself a day to do it and i was twidling my thumbs by 10.30am, the rad sits on hangers so you can remove the bolts and lift it out quite easily when your comfortable, just be careful you don't mash up the core on the new one when you slide it down. a milk crate or steps of simulare height are very usefull.
i gave my new one a blast through with the hosepipe just to make sure it was cleare of any kind of particles because the hose holes wern't caped off.

i wouldn't recomend rad seal of any kind but if you are really in the sh12, wynns rad seal, is better than rad weld, rad weld is kagmag.

for what its worth i would replace the rad with a manual version ( as it has better flow coz there isnt a box cooler built into the bottom tank) one and install a seperate cooler for the box.
