    Lightbulb 98" express 6.5TD coolant lose

    Hi
    Found recently that my van losing coolant. checked oil-clean, oil cup-no trace of coolant, leaks all round-dry and any single drop of coolant on the ground. When I start the van i got no white smoke or coolant odor! I heard there maybe a crack comewhere or headgasket failed but live with hope not to get that...)

    Hove can I check the engine properly????

    By the way, the pressure in expansion tank checked also when cold and hot, all seems to be good!

    Thank you for any help

    I would go to a local autoparts store and rent a coolant pressure tester. Hook it up and pump around 15 psi of pressure into the system. Generally, even small leaks will be shown when you do this. If you don't see the leak, listen for it. You will hear hissing as air escapes the system. Hopefully it is something easy like a bad hose clamp or even a water pump gasket. Please let us know what you find

    I find that very interesting. Here when you rent the tool from the store the kit has all the adapters needed for domestic and foreign cars.

    I broke down and bought the mityvac kit myself. It worked very well and found the leaks I had at the time. So not sure if this is available to you there?
