Radiator Shroud
« on: February 12, 2017, 05:11:38 PM »
My 2A runs hot. It has been flushed, radiator replaced with a new one, all hoses OK, fan belts and blade OK, temp guage shows within acceptable range, ignition timing OK, but it definitley feels very hot. I'm thinking it could be that the shroud is missing but I have not been able to find one.

Has anyone got a spare they don't need?

Borrow or buy an infrared heat gun and check the block temp.

My shorty seems pretty darn hot, but the block only comes in at 82c.... which is about the thermostat temp.

Good luck  :)

On the cards check for a super clean exhaust (steamed cleaned) or milky colour engine oil or the exhaust valve timing (not the same as ignition timing) or the old exhaust lash gap to small caper?

Mate it has been hot though.

Just for giggles Id bench test the temp sender.

Immerse the sender still connected to the loom with the ignition on in hot water with a thermometer in it take it up in heat from when the thermostat opens up to boiling and see what the gauge reads in the dash. Then you know you can trust it. Shrouds only earn their keep at slow speeds.

Hi Kman,

When I purchased my shorty it was missing the fan shroud and it did run hot a few times and almost overheated once.

When I fitted  the shroud it made a huge difference in running temperature. I wouldn't start replacing anything without fitting a shroud first.

Sorry I can't help with that.

Good luck,

Mick
