220D Sel Coolant Loss

[tomcross45]

hi folks can anyone shed some light on coolant loss after a 50/60 mile run the header thank is empty .pressure tested ok.new cap has me puzzled

[dgman]

check the water pump,most likely culprit.

if there is no visual leak, then it is the engine head seal

I forgot to add, that if it really is the gasket, or damaged head, do not drive...the coolant will contaminate the oil and the engine will seize.

I had exactly the same a few months ago - pink deposit everywhere in the engine bay, complete loss of 90% of coolant virtually daily. Lexus initially said it was water pump and changed it but when car came back was still suffering loss so they re-examined and it was the gasket.

Get a block test ASAP. I've just had a new block and head FOC

DO NOT DO THIS WORK YOURSELF it will be warranty up too 7 years or 120,000miles it was extended due to the pink cooland eating away at the head gasket....100% of the time this req a new block and head as the gasket shuffels and wears grooves rendering the block and head scrap.....

i myself have done many of these(not on the lex but on the rav 4 and avensis they are the same engine)

hope that helps,

ps it is very common we have 3 in now getting full rebuilds free of charge..

ormi,after fixing those engines is a different type of coolant used and should we all be using this.i don't suppose that you could post the technical service bulletin could you?
