Hi guys was just wondering if it would be easier yo replace the engine or the head gasket.
Symptons i have are whilst driving round town temp sits in middle but fans come.on constantly. On a run at 75ish temp boils right of red line. Slow to 60 drops to normal as.quick.as speed drops

Bought from bloke who said put went and he replaced it. Thwre was no heat from heaters which i sorted by flushing system completely and fillin heater by disconnectin pipe from back of stat housing. Still boiled up. Took stat out now temp sits between 95-116 from the dash trick. Bubbles in expansion tank. So thinking the gasket has gone. But what is the easier job. Pls

 

That all depends if it's a Veyron or a fiesta how much work is invloved. HG will always be easier to do, depends if it's worth it though.

 

Oh yeah i forgot bout car its a 2001 focus 2.0zetec

 

Sorry just seen what i wrote with my clumsy claws on my fone. It was the pump that failed and got replaced. Was ok for bout 700miles

 

I'd say head gasket would be a lot easier. DIY provided you know somewhere to give the head a skim (any engineering shop should be able to do it)

 

Cool do all the cams need to come off?

 

have you checked that the actual coolant rad isnt blocked or you've got an air lock in the system? and a head gasket would be far easier imo!

 

Have bled system completly ripped rad out and flushed. Refilled according to ford tis. Still boiled up. Put some seal-up liquid glass. Now have hardly any pressure build up but the temp still hits 100c with stat out.. poss pump prob was told it was changed but no guarantee. Looks new though

 

Dodgy water pump?

Not sure if these would be the same but the mk4 Golf water pump has plastic impellor which often breaks up,
Or sometimes the pump turns but the impellor doesnt, It just sits on the shaft which is more noticable at higher RPM as the Temp rises

 

does the level rise or differ when reved?
would rule out the pump if you can see its doing something and if the level didnt rise or change then maybe pump probs

 

When revvin the level sinks a bit. Randomly will spit a bit of water out when droppin revs

 

Did put some of that stupid wondaweld in as local motorfactors was closed. Could this of got in oil causin overheat.

 

Given up explored all avenues. Gonna scrap it. Cba with it no more
