Celica Forums General Discussion Engine and Performance 03 VVTL-i Constant Overheating :(

Hi guys,
Any help would be great!

I've taken my 2003 Celica (6 speed) to 4 mechanics so far with no luck.
It keeps Overheating.
First mechanics flushed the radiator, stuck some seal up in it, and did thermostat and gasket but it still overheated and had coolant in my front seat, so we bypassed the heater core. Ran fine for months, then overheated again.
Gave it a service, did another thermostat, radiator cap, flush and new coolant. So on and so forth, but it is Overheating again and I am getting over it!
Please help!

Looks like coolant lines got plugged up somewhere blocking the flow of coolant.

Try the calcium dissolving chemicals in the radiator according to instructions. It may remove the blockage and problems with cooling system.

Tap water tend to have minerals which calcify and block coolant lines after a while. Use only DISTILLED WATER with TOYOTA coolant.
