this evening i turned it on again the water temp is fine now on a quarter.
but i still cant go over 45 mph and the 2500rpm again

can anyone help me out please as i need to get to work this week

Check for head gaskets faults mate,

Have you lost any water? or is there blow back in the rad tank?

If it boiled up really fast and there was still no heat from the heater, could this not mean something had frozen somewhere? If the engine is getting too hot the heater should be really hot too unless the water isn't circulating properly.

could be the radiator have you tryed flushing it at the holes at the bottom over time get filled and blocked there was an article in lro a few months or years ago one overheating il have a look at sum old ones i onli had it out a few days ago as they never get borin
