Driving home last night and the Starlet decided it would blow a bigger hole in the radiator, steam everywhere
There has always been a small leak which I couldn't fix and the rest of the radiator was on its way out with rusty bits and the cooling fins disintegrating. This is the small half sized radiator so cooling efficiency was never great and going up hills or high load on the engine for long periods of time would make the temperature rise 2/3rds up the gauge quite often. Occasionally I would use the heater to bring the temps down faster. The odd thing is the temperature will also go down to 1/3rd on the gauge sometimes like going down hills.
The new radiator I picked up this morning from Able Smith Radiators is a full size one so this should help with cooling although a new half sized one would work too but they stopped making them. The differences in this large one is obviously its size, the bottom right mount and the top right mount position and the drain plug location. Everything else is the same. So to mount it all I had to do was find an M8 nut to go on the other end of the right hand top mounting bolt. Luckily there is already a mounting position on the radiator support bar and a hole, just no captive nut. The bottom right mount remains in place on the car, the radiator just sits on the mount rather than having the pin fit into the rubber bush.
Still yet to test it on steep hills and in traffic but I'm sure it will work well now.
