Hi all, grateful for any advice on overheating issues, have removed the thermostat, flushed the rad and cleaned the cooling fins, my old girl gets hot after about 20 mins, so I've found out if I open the hood and squeeze the top hose a few times the temperature drops immediately. I can then run for a bit longer until temp goes up again, repeat the process etc. I can only assume its the water pump. I'm looking for some confirmation or is there something that I've missed. Pump looks a PITA to replace, anybody had experience of this? that's if I can find one. Any input would be gratefully received.
