Engine Install – Radiator and Fuel System (3 hr)

First thing today was to determine what was wrong with the radiator brackets and it didn’t take Allen 15 seconds to point out that I had put the radiator on backwards. The radiator doesn’t have a right way up, but I had missed that it has a right way around. Actually, if I had skipped ahead to the next part, it would have been obvious because the hose outlet would have been on the wrong side. Moving on….

The mounting bracket on the passenger side now sits nicer on the radiator but it is still very close to the fuel pump vent (which I assume I have to put some hose on) so Allen gave it a talking to with Mr Hammer so that it didn’t interfere as much. We probably need to grind some more of that out.

Radiator Bracket

We also loosened the exhaust assembly and pushed it around so that the passenger side tubes were further away from the radiator, leaving us with a much better gap. I still think I should firesleeve some of the hose near the exhaust, and probably heat wrap parts of the exhaust too, just to be sure.

The hose from the radiator to the water pump comes out and down under the engine. Much easier to get this hose onto the right parts, each join getting a clamp and some safety wire.

Radiator Hose Install

One thing you’ll notice here is that changing the oil filter will require removing the radiator hose. Not very good planning!

The other line came round the side and to the back (and into what I don’t remember!!).

Radiator Hose Install

Once all the parts are installed we will definitely review hose routes, stand offs and other burning/rubbing hazards, but for now it looks like a good start.

There’s a tube that goes from the engine to the expansion bottle.

Reservoir Overfill

After that we located the hole for the fuel line to come through the firewall into the gascolator. This is a bit weird because the gascolator sits against the firewall in such a way that the fuel line barb angles down into the cockpit so it is quite a tight space to install the fuel line.

Gascolator Mounting Holes

We riveted it on to the firewall but I didn’t take a picture. We also looked at the fuel pump but I felt we had to wait so that I could look at the instructions for the fuel flow monitor in case there were special instructions. There are: it has to go downstream of the pump but below the fuel line from the engine.

Lastly, looking for things to do, I drilled the holes for the rectifier install

Marking holes for rectifier

This isn’t actually how I ended up doing it, but it makes for a better looking picture than the paper cutout I made. I didn’t have bolts to install it on the firewall yet but it is ready to go. No, I have no idea what wires go in there.
