Can this kink cause excessive engine heat?

Post by Dumindu »

My car is a Toyota Tercel 1987 4WD 1452CC DX Wagon.

Recently I could experience a dangerous situation where engine temperature rise excessively and radiator hose ruptured.

I disassembled some parts of the engine to find the cause.

I could see the following kink in the hose which connects the engine head water channels to the engine water pump. This kink seems blocking the channel.

Can this cause the excessive heat?

I doubt that would cause heat. That is the hose to the heater core and there is a valve on left end that closes water flow when you turn heat off from climate control panel on dash. A kink would do same as valve.
Love those Tercell 4x4 wagons but they sure suffer from road noise.

that is correct, that only goes to the heater. It would not cause an overheat event.

you either have a leak (small ones are had to find, they only leak when they are hot and pressurized and than you only get steam, not a fluid leak), or your head gasket is compromised and you loose coolant out the exhaust as steam, until it will not have enough coolant to keep the temperature down.

could also be a plugged up radiator, usually that occures slowly over time, not all of a sudden.

good luck.
