coolant level

Took the car back to the dealer after it overheated in traffic (steam around the expansion tank, etc). Apparently the second fan wasn't coming on.

Just checked the coolant level for the first time since being fixed, and it's near the bottom of the expansion tank such that I can see the holes in the tank where the coolant comes in and out. Topped up to just under the "ridge" (about half a finger's length down from the filler cap).

I guess if I could see the holes then I've been sucking air into the cooling system and need a bleed?

Mine uses a bit of water ftrom time to time, I'd just fill it and it should sort itself out, keep a check on the temp guage, If you get an airlock it will keep running up to max and coming right down again, had it on a 350, never on a Cerb

On the RV8 powered TVRs any air that gets to the radiator is trapped there, so you'd need to bleed the rad now. Don't know if the Cerbera plumbing is the same though.

Should be: The Cerb fans were an upgrade option on Griffs, which suggest the radiators underneath are compatible.

That only suggests that the fans fit the rad -- it doesn't necessarily imply that the rad is the highest point of the cooling system on a Cerb.

my temp gauge has little kicks up and down when I'm stuck in traffic and I'm sure it's air in the cooling system but I'll be damned if I can find it.
The bleed screw on the rad shows that the rad has no air in it so I assume there is a higher point.

Somebody said that the two pipes coming along the side of the engine then down the front are for the cooling system and that the two valves on them are for bleeding but that wasn't a definate answer (they might be for A/C though).

When I get home I'll try and open them as my A/C is empty just now and see what happens.

The mechanism seems to be top up the tank, open the plug on the top of the radiator. Its exposed so no bodywork needs to be removed, and let the air bleed out.

Then top up the tank, and in turn release the air valves on the top of the engine under the fuel rail either side at the front, by cracking them half a turn and waiting for the air to bleed out.

finnally top up the tank.
