Build 19. Radiator and Fan

As per every stage I started by locating all the parts that were needed for this to be fitted. The process can be split into two stages, first fitting the radiator, and then the fan. Two of bolts that are used to attach the radiator to the bobbins (rubber mount) are already installed in the radiator, the other two (M8x10mm) were no where to be seen, so I simply ordered some grade 8.8 M8x10mm bolts from Amazon to speed up the process. The rest of the bolts were in Pack D and the bobbins were in the unnamed bag that contained the cooling parts.

I'm building the SV so the first job was to fix the SV brackets to the chassis ready to receive the radiator, there is no documentation on this part, but basically it entails connecting two metal brackets (as seen above on the right) to the chassis, the the bobbins will attach to this, and then the radiator on the bobbins.

Make sure the bracket sits on the inside of the black brackets on the chassis, and you have a washer on each side of the bolt. I fitted these so loosely that they could wiggle a lot to make fitting the radiator easier.

Once the brackets were on I then attached the bobbins using a washer and nut on the back, I tightened these up fully at this point. Next I offered up the radiator and using a slim 13mm spanner I loosely connected the top two bolts to the bobbins (my normal spanners did not fit so I used one that I had lying about from a previous Ikea build or bike build).

In order to get the bottom two bolts on, I had to temporarily remove the oil radiator that is already attached to the bottom of the water radiator, I could then bolt and torque up the lower bolts easily, I then tightened up the top ones too. I think I bolted them to ~20Nm as it doesn't state a value anywhere, and I don't think it is ideal to overtighten these as the fittings seem quite weak!). I then reattached the oil radiator on the bottom.

Next up was to fit the fan, The manual doesn't mention the need to fit the 4 black plastic adapters, these were found in the unmarked bag in the cooling box, to get them to fit I needed to use some silicon lubricant, and quite a bit of force. One of mine broke slightly, but not enough to compromise the fitting. Once I had them mostly in, I used a nylon hammer to get them to sit flush in their holders.

In order to be IVA compliant, you have to use half height nylocs that are provided, and you will have to disregard the instructions to use washers. With the washers on, there was not enough thread sticking out of the nut. These were tightened hand tight, and then only tightened up a bit more from there. I was worried that I would break the plastic, as I had seen others do this on other blogs!
