if it takes awhile say 10 mins could be thermostat. if it happen quickly 3-5 mins lots of pressure in the water system head gasket blown? big job most expensive

how do u bleed the water system on a tigra?

it could be 1 of 2 things
1 water pump has gone
2 head gasket has gone

to check to see if the head gasket has gone remove the oil filler cap and look for white creamy deposits if they are present then its the head gasket if no deposits found then have your water pump checked over hope this helps phill.
