1. Are the fans kicking in and out! 2. Are all the water hoses hot (top, bottom and heater)!

take the belt off the water pump and see if it has a bad bearing. On our stellar which has the same engine I think it had a crook bearing and that meant that the angle of the impeller was such that the water stopped pumping.

Thanks Morrisman1 will give that a try

1. Was there any signs of rust or corrosion in the coolant when you changed the thermostat! 2. When the fans kick in and out, does the whole radiator core feel hot!

the water was red so thinking that may be a sign of rust! yes the whole radiator feels hot

Blown head gasket or worn ringsas well as any or all of the above, cracked head, or if getting close to 250,000 kilometers just worn out.

change your radiator cap,look at your oil filler cap, on the underneath side for water in oil,test your themostat, or leave it out.,use antifreeze to raise the boiling temp,use motorup in oil too,but most important, is there strong circulation of water movement in the raidator,as the water pump could be issue, but dodgy raidtor cap could slip under the rader, and right pressure, and dodgy workshops play silly buggers with cars too

Agreed^^. Leaving out the thermostat can cause alot more overheat issues with a bypass type system. Motorup is a complete waist of money
