Hello

My car ('59 series 2, 2.25 petrol) has just started violently overheating.

It's just been mostly rewired, after spending a few months standing.

After about 5 minutes of idling, the temperature needle shoots off the scale and (after a little longer) the engine bay fills with steam.

To complicate things, I can't find a drain plug anywhere on the radiator and the engine isn't original.

The VIN number shows that the car was built with the early diesel but I know (it's fairly obvious) that the car now contains a 2.25 litre petrol, and it's clearly been in the car for many years.

Also, my radiator cap has fallen apart, with only the very top bit - minus the spring loaded part - remaining.

Personally, my suspicions include the thermostat (possibly broken), a radiator blockage (which I'm struggling to do anything about since I can't find a drain plug) and possibly a water pump problem.

I've, almost certainly, forgotten something, but that is roughly my problem.
 
It sort of misfires from time to time - as if it's rushing through the revs and getting ahead of itself and then making an almost popping sound.
 
I've never seen a radiator drain plug. I just disconnect the bottom hose (while it's cold of course). When the car overheats, is the radiator hot/hot in parts/cold? Where does the steam come from? It seems odd that it should steam up so quickly - mine (2 1/4 petrol) takes a lot longer than 5 minutes to heat up, even on tickover. My suspicion would be no water in the engine block, as that would seriously overheat with no cooling.
 
As soon as you start the engine do the coolant hoses get pressurised?
Is there alot of water/condensation out of the exhaust?
Both definative singns of head gasket.
Do all of the hoses get hot or just the radiator ones?
What about the heater inside? hot or cold?
Did the problems come all of a sudden or got worse over time.
 
I've never seen a radiator drain plug either - my knowledge is based upon the Haynes manual.

The radiator generally remains reasonably warm (rather than really hot) at first when the dial goes beyond the red. After a while, it gets hotter.

I'll check most of those next time I get a chance.

I keep the heater disconnected because it leaks badly otherwise.

The exhaust has been 'leaking' out of the joint next to the exhaust manifold in the engine bay and it did look fairly white. Steam?
 
If everything checks out ( no pressurising, Heater working) it could be a simple air lock.
Try running engine with rad cap off and heater on full hot.
Dont know much about series, my joy is a defender
 
Good luck and if you put your location on your profile there may be some brain boxes on here who could take a look
