Hi all,
Drained and refilled my cooling system at the weekend after changing the main tank, thought all was ok but still needs some attention after checking the level in the main tank yesterday evening (first time I've checked after van cooled). The level was about 70% in the main tank and hadn't changed in the tank behind the number plate, it's my understanding that as the cooling system cools the liquid contracts and then pulls liquid from the tank behind the number plate. After researching and from the knowledge I already have this can be caused by a leak in the system where air is drawn in rather than the liquid from the 2nd tank. I was thinking of purchasing a pressure test kit of ebay to test this as I can't see any leaks from an initial inspection but wondering if it will end up in the bin after a few uses! Anyone have any experience or even know if a cheaper kit will fit these old vans?

Going to check all pipe connections thoroughly and top up/re-bleed the system to see if I can find out what's going on. The dalek cap is new, it came with the replacement tank so thought a good idea to use, haven't done the test by blowing into it so will try that in case it's a cheap one.

Re: 1.6 JX Cooling System Issue
Make sure your dash heater lever is in the open position and heater under rear seat if you have one. Top up your main tank, get it warmed up and open the rad bleed screw to see if there are bubbles. If you still have problems try another cap, the ones that come with the tank can be dodgy.

Re: 1.6 JX Cooling System Issue
The caps supplies with the new tanks are only fit for the bin, a pressure tester is handy for bleeding the system, but you would be better to spend the money on a decent cap first.

Get a cap from Brickwerks.

Re: 1.6 JX Cooling System Issue
When I changed my engine it took a good hard drive to burp the last of the air out of the system. Normal bleeding had still left some in there, so I wouldn't worry if it has only happened the once since the coolant change.

Re: 1.6 JX Cooling System Issue
Great, thanks for the advice. I did buy a brickwerks a few years ago, thought a newer one would be better. I was wrong!! Kept the brickwerks one so will swap over. Looks like all my evenings working on the van this week... (got an electrical problem which I think I’ve caused myself so no one to blame!)
