Ovrheating of engine should be due to a cooling system fault. Either is insufficient coolant in system or the fans, radiator, water pump or water passages have a fault.

Was any repairs done to the brakes prior to them locking up? It has nothing to do with the engine overheating.

After replacement of the hose, you need to bleed the system of air, failing hich I is going to overheat.

With radiator cap off, topup the coolant and start engine. When level drops, top it up. Run for about 5 minutes and stop engine. Top up coolant if necessary and close radiator cap.

Run engine to operating temperature and stop engine. Wait for it to cool doen and recheck coolant level. If it is low, top up and run engine foe 5 minutes again, topping as required.

Close radiator cap and run to operating temperature again. Check for leakages.

If the brake pedal locks up, it could be the brake fluids are not returning to the master cylinder due to insufficient clearance between the brake pedal and booster push rod. This would heat up the brake fluid causing them to lock up after some driving distance.

hi thankyou so very much for everyones help, much appreciated.
I found a green plastc thing with hoses connected to it, one end of hose was off the green plastic thingie going to brakelines, one hose was cracked at both ends so I fixed that and reconnected, found a second brakefluid cyclinder nearly empty refilled that with brakefluid, refilled radiotor with coolant, and all seems to be going ok.P.S. If anyone in Hobart Tassie, knows of anyone selling a good reliable clean car 4cyld upto $1000-$1300 please let me know, ive been saving for a long time and im a tad worried about buying a bomb and being ripped off, it will take me another two years to save up again to buy a car, so been trying to keep the corona going for as long as I can. Thankyou for everyone for your help. Marcus
