coolent pipes v6
 

hi all ,

have had a loss of coolant for a while now .
its looking like its around the drivers side front.
have today taken the undertray off and if thats to go by then it does comfirm this . also the engine temp is a bit out of sorts . can run as low as 80 then up to 100 in a few seconds .
now it would seem to happen only when car is running as with the engine off no sign of drips. have to top up 2 or 3 days.
car is up on ramps at the moment with no oil in so I cannot start her up till tomorrow.
just thought I would put it out to see if someone has a idea what pipe it could be.

thanks

There's a pair of steel pipes that run across the front of the subframe, that's where I'd start looking ;)

They're only flash painted and have a nasty habit of corroding and have been the cause of many leaks in that area ;)

Next look in the V beneath the inlet manifold for the thermostat leaking ;)

Start by checking in the 'V' for signs of antifreeze residue or even pools of coolant. Then inspect the metal oil cooler pipework under the radiator for corrosion.

Have you had any work carried out on the cooling system prior to this problem occurring?

Not as you describe but my daughter's V6 suffered two loses of coolant, both times the large hoses from thermostat to radiator. One was very sneaky as it had a sleeve and only by splitting the sleeve could we see the leak, I think this sleeve was deleted later in the programme but as your car is an early one thought it worth a mention.

Regards

hi all.
v is dry had the inlet off last week .
its a right pain to track down as not much room to play with
oil cooler pipes look ok.

may have to wait till I can start it up .

thanks all

I had an intake manifold to head gasket spring a leak.
As for the steel pipe assembly across the front of the engine Rimmers currently has them on clearance along with some other V6 hoses.

Water pump and inlet manifold gaskets should be checked.

What price clearance did you see please. Checked their site and they are £93 plus postage.

If you go to the home page on their site and click the "Mega Clearance" banner you will be taken to the sale pages. I just bought the metal pipe & hose assembly for 60. quid. They have several other 75/ZT hoses on clearance as well as other useful bits.

Isn't there a stainless steel version of that pipe assembly somewhere?
