Thread: Rover Diffs in a IIa SWB

My 2.25 petrol ser 3-- 88 runs 4:1 diff.
I was running 32 inch dia tyre and swapped to a 28 inch this week because Im fixing noise vibration. had axle lockups.

with the 235 85 16 [32 inch] tyres it would easy get to 100KMh and hold 110kmh. if you loose speed on a hill I have to wait till it dies down enough to use 3rd gear.

with the 235 75 15 -calculator shows 28 inch- sand tyres that came with the 88 it sounds to be reving more but it holds speed on hills.

I removed the original radiator fan last winter as the heater was struggling. Now you cant tell it was reving hard. I gained another factory blade I fitted a few weeks ago that looked newer and is very quiet. I can hear the in front radiator electric fan turn on quiet.

interesting that you removed the fan.
in the log that the previous owner kept for my car, there is a note saying 'must refit fan for summer'
and in talking with him when I was buying it he mentioned he took the fan off for winter.

it did come from northern nsw and where it does get cold in winter.

Should have fitted one of these DA2160BLACK | Radiator Muff - Series 2A and 3 lights in wing - black - Paddock Spares

Common in the UK. My Mum had a Wartburg wagon that had a cable operated radiator muff so you could raise or lower it on the fly.
From memory the actual radiator was behind the engine on top of the gearbox, fan belt at the front of the engine and a countershaft through the head. For some strange reason it always ran cold, smoked a bit as well......
