Hi!

I have a Jumpy 1 with the intercooled 2.0HDi form 2006. Bough with 230 000 km from an old tyre firm. Seems to have had issues with loosing coolant for quite a while, notised residue from coolant under expansion tank, sender for coolant level disconnected, tap water instead of coolant in the system (fucking hacks...).

Anyways, girlfriend and I made a van conversion of it and we like it, but it looses coolant. Over 500km it empties the expansion tank. I seems to seap out near the cap. I recently replaced with an OEM calorstat one but it persists. I sure hope it´s not the head gasket...

The can doesn´t smoke, temperature shows 90 when driving. Got a little hot once when there was ice in one of the hoses (due to the previous moron of an owner running tap water). thermostat seems fine, it doesn´t seem to build excessive pressure in the cooling system. If i open the cap after letting it cool down for 10 minutes it makes a faint "pssht" sound like a coke bottle but no gushing out of liquid or anything like that.

What would you do to diagnose further? Try a new expansion tank? The one on the car seems a bit shit. Any good aftermarket options or should I go oem?

Also if anyone wants to add keyless entry for less than 25€, here´s a guide I made:
