[W126 Coupe] 420 SEC coolant system problems

[Mike Ramay]

See if they can put the tailpipe emissions test probe into the overflow tank
- any readings of HC, CO, or NO is definitive proof of a blown head gasket.

Hi guys,

 

unfortunately it turns out its the head gasket, the guy didn't want to do
the job either but he was getting on a bit. He put a hose with a funnel in
it onto the radiator cap and let the engine run for a while, topping it up
with water every now and again. after a while bubbles started appearing and
when he revved it more bubbles would surface. Does this sound like a
scientific enough way to determine if its the head gaskets need replacing ?
He seemed knowledgable and was recommended, didn't charge me either for the
30 mins he worked on it.

 

Am i right in thinking this jobs needs to be done at least once in a car's
lifetime or not ? just trying to look on the bright side ,

 

thanks

 

Oisin

Hi Markus,

 

thanks for your help, I also noticed a whining noise which wasn't there
before, another forum suggested it may be a water pump bearing. I'm not sure
what units the temp guage is in, can't remember if it says C or F, either
way it was reading at the bottom end of the guage and was nowhere near the
red area, could also have a faulty sensor then as its not reading 80 which i
think is normal, will double check my guages and see if its C or F,

 

thanks  very much, all the best,

 

Oisin
