If a garage replaced a head gasket and charged for it but then it failed around 9 months later, should the garage have to replace it ?
A few days after I bought my car ( about 9 months ago ) garage diagnosed and charged £955.58 to replace it ( though later found out they lied and replaced only the water pump but did not confront them as had no concrete evidence)
Recently I replaced expansion tank because it had a leak ( replacement tank is a used one as needed it asap and couldn't wait 1 week delivery for new one )
I notice several days after topping up the level dropped ( at first thought it was just disposing of excess water) but then it went near to min level. also notice which is odd, coolant looks slightly higher when cold than it does when water it hot.
I replaced hoses a few months ago when they were leaking, can't see no leaks, car runs fine, (slight power loss but assume that is due to faulty MAF), no smoke whatsoever from exhaust, no contaminated oil e.t.c.
any ideas ?
