Shogun V6 3.0

Recommended Posts

I've picked up a Shogun Sport 3litre V6 auto (Hreg) and the engine gets incredibly hot. The temperature guage is fine and stays constant but the engine itself emits a LOT of heat to the point where you can feel it in waves from the wheel arches and the panels become hot to touch, any thoughts?

Firstly i would be suspicious of the temp gauge, change it. Second could be the water pump, third electric fan not kicking in at correct temp.

I assume there is plenty of coolant and it isn't 'air locked'.  Some vehicles where the engine top is above the radiator top need bleeding to get the air out of the top of the system (like a house radiator).

Normal temperature on modern engines is often about 85 centigrade - which is why the systems are pressurised (raises boiling point).  This is (much) too hot to touch.

Normally any significant overheating caues boiling of the coolant.

All V engines have two exhaust manifiolds (one each side) which is a lot more very hot metal than a straight engine and this does lead to high underbonnet air temperatures.

There may be nothing wrong if it has plenty of coolant and the coolant is not boiling.

two exhaust two alley heads a lot of heat check the  radiator is clear and not full of dust and **** , if temp gauge does not fluctuate it should be ok , if electric fans  normally don't come on when driving but when you come to a stop all hell breaks loose to pull the temp down quickly  ,   if it puts your mind at ease you can but a head gasket leak detection fluid kit off auction site for a few quid  https://www.ebay.co.uk/itm/HEAD-GASKET-BLOCK-TESTER-KIT-COMBUSTION-LEAK-Detector-PETROL-DIESEL-60ml-FLUID/323595490612?hash=item4b57cb5534:g:z-EAAOSwcUBYSV0k
