V6 coolant bottle empty

Ravinder · 21st February 2021, 19:18

Not driven the V6 manual 190 since early October. I went to check the coolant level the other day and the bottle is bone dry. Is this normal if a car has been standing for a few months?

I put in 750ml bottle of water into it but it went straight down and the bottle is still completely empty. A little worried.....

The engine has had a rebuild in the last few years before being fitted to the car.

Not normal - check my V6s perhaps once or month or before a longer journey, hardly ever need to add a drop. Sometimes after draining you might need to top up but yours sounds worrying.

Good luck

Are you sure that your anti freeze was correct before the freeze? It's easy to forget to check it,

The coolant level has never dropped in my two v6's and two diesels and my dads diesel except for 2 occasions when there was a minor leak. Would check for common leak areas such as the thermostat.

I had a similar problem - turned out that the rubber hose that goes into the bottom of the expansion tank was rubbing on the air filter housing lip and had made a small hole. It is also worth checking the rubber hoses and metal tube that run along the bottom of front subframe as there is opportunity for some 'chaffage' there. In the end I just replaced the hoses.
Also - watch out if your coolant level drops too low as you may have to bleed the system when topping up otherwise you end up with air locks which just add to your misery

Leak in the v, thermostat housing. Happened on mine a few weeks ago 2 8mm bolts to remove engine cover and shine a torch in, you can see coolant pooling. 2 minute job to check. Surprised as it was less than 4 years that thermostat housing and pipes where replaced.

Hi Martin,

It's leaking because the 'O' rings have flattened and the cause of that is movement of the three plastic parts. The solution is to fit new 'O' rings then crucially move the two serrated clips on the straight pipe fully outwards so that they are hard up against the water pump and thermostat housings. This renders the whole assembly rigid.

I discovered this through painstaking research and experimentation on my own car which has been leak free ever since.

By the way Martin, your profile doesn't mention a V6.

I think that Mike is suggesting Ravinder that following your engine's rebuild, if plain water was used rather than antifreeze solution, it would have frozen during the recent cold spell and caused a leak.

In your shoes the first thing I would do is top-up the expansion tank to the 'MAX' tab inside and use the car regularly whilst monitoring the coolant level. At the first sign of loss, look carefully for traces of antifreeze solution.

190? I think not

That car is fitted with a cheap and cheerful DGMRS Chinese thermostat, I'd make sure the straight pipe hasn't split like the previous three that were supplied in March 2017
