Hey, wile trying to find an odd cooling problem today i thought i should
film everything. The van came in and the owner told me it was overheating,
strangely and that this was intermittent, he also told me that he loose
coolant in the EX tank and he as mostly no heat in the front.... OK.

Head gasket/head crack, maybe, maybe not.

Have fun:
