Hey guys,

need some help with my 300 tt my car started to overheat one day whilst driving when I pulled over on my drive there was water all over on the road. had it checked by my mechancic and confirmed my radiator needed replacing. i bought a standard radiator through ebay recomended by a club member. after having the radiator replaced and running the engine whilst parked one of the hose pipes connecting the radiator to the engine cracked and statted to steam. the mechanic cut the cracked side and placed it back and the same problem repeated. i had the thermostat removed and checked and it was all clear. the mechanic left the car running and there was no problem amd as soon as he started to drive after sometime the same thing happend and had to leave it on a side road..he assumes the head gasket is gone but im not fully convinced. has anyone had a similar problem if so what can it be or what can I do?

 

many thanks

I beleive its the intercooler hose pipe that im refering to

Take a picture of what's cracked, the intercooler pipes don't steam, them only contain engine gasses.

Make sure the thermostat is fitted the right way up. Its a very easy mistake to fit it incorrectly.

ill take a pic tommorow once I have it towed back..the problem was there before even after putting the thermostat back. the mechanic says he feels theres alot of pressure coming through. but is that not normal for a 300?

I had a major head ache with my over heating zed, first started when the thermostat failed to open fully and it ended up putting its coolant over my friends brand new drive. once id found the cause (thermostat failure) and having replaced it, it developed a problem where by it would systemically burst all the old water pipes around the engine.

 

Get him to do a block test in front of you, this will confirm or deny the possibility that the head gasket has failed and is letting cylinder gasses into the cooling system there by causing excess pressure.

I agree with vods... I also think if the water pump is not working, it will cause water to stay in the block too long and overheat.. also causing the water to boil/steam...

 

strangely enough the block test might be the easiest thing to do... Oh, and not slagging off your mechanic but you're better off getting someone (reputable) who is familial with Zeds to do it.

 

good luck.

Thanks for the advice.im still waiting for my car to be returned. the problem I have is theres no mechanic around where I live that know the in's and out of these cars!!!!
