Today, After driving 50 miles in a round trip, I was out of the car for around 10 mins (with the engine off), then when I got back, and started her up, the temp gauge was nearly through the roof. Is this usual, and is the engine made for this, or is it something to get sorted as last year she overheated and it took 3 months & 3k to get her back.

 

Cheers

Hello Daz

 

Might be an idea to check/clean the temp sensor.

It's not usual and could be a 'ucked sensor and needs investigation, but I have to ask what cost 3K to "get her back"!

Buy another one for that!.

The water stays cooler because it is circulating round all the time. When you stop your engine, the water stays where it is. If the water is in a place where it is hot, the water will get hotter and hotter, because its not being pumped through the radiator to cool down.

 

Its like put a kettle on, but you had a pipe out of the bottom of the kettle where the water poured out and went through a radiator to cool down before its poured back into the kettle.

 

The water will never boil because as the water starts to get hot, it leaves the kettle, cools in the radiator and the put back into the kettle, and it keeps going round, heating and cooling.

 

However, if you stop the water from circulating round, the water in the kettle will boil becuase its not cooled down.

 

Its exactly whats happening in your car. When you turn your engine off, it is still very very hot, but because the water is no longer moving around, the water inside the engine gets very very hot while the water in the radiator is cooler. The water temp is detecting the water just as it comes out of the hot engine. I bet the temperature came down with in 30 seconds of starting your car again.

Interesting explanations but to get back to the bit

the temp gauge was nearly through the roof. Is this usual

no it's not.

Sorry nothing to do with this post but the added thing on the bottom of my post works, eeeeee!

Cheers,

 

But it looks as though the only way to get it sorted is to let SE have the old girl again.

 

Thanks again ppl
