all these theory's are valid possible ones .........
but i don't see the most simple , small yet VERY important part of all the parts you mention and the procedeures you have undertook ?
- the actual Radiator Cap itself ,
- last time i checked a CSF unit did NOT come with a new cap ?
this is a LOW cost part to cross of your list and CAN cause your list of symptoms ..........
see link below :
no matter where u source your NEW cap , make DAM sure it's a Genuine NipponDenso JAPAN , part and DOES have the ND logo and the all important 0.9 stamped on each outer ear like shown below
- sometimes it is the little things :
NON-USA OEM TOYOTA LOOK and SEE the ND NipponDenso JAPAN stamp settle for nothing less then top shelf cooling system...
