Hi everyone,
I had my gtv's thermostat replaced last week and when I moved the car this morning there is a small puddle of coolant underneath.

On close inspection it seems to be leaking out of the hose where it connects to the thermostat and also out of a bottom hose that I think may lead to the radiator?

Could the hoses have not been re-fitted correctly? I didn't notice any drips after he'd replaced the coolant and the drive back was fine.

I didn't want to poke around too much in case I made the leak worse!

Thanks

I would check you haven't got one of those dodgy thermostats that are about.

How do I check if the thermostat is dodgy? It seemed to work fine on the drive home?

They split where the plastic meets the alloy on the outlet.

OK, cheers. I'll take a look

OK, cheers. I'll take a look

Please check, I had a small puddle under mine last Saturday, I had washed the car elsewhere shortly before, so when I came out the house and saw a small puddle I didn't think anything of it. On Tuesday my temp went up and this was the result.

Thanks for the reply. Jeez that doesn't look good! Mine seems to be OK, can't see any splits in the thermostat. Just a slow drip from the underside of the hose where it connects to the thermostat.

And another drip from the joint where the bottom hose connects to the block. Maybe the clips are overtightened? Can't see any obvious split in the hoses

It's a crap design tbh as the stat isn't srperate replaceable I can't see why they didn't fix it properly and not bond it

Hi when I changed my thermostat, I noticed there are little plastic nubs on the thermostat and reciprocating slots on the pipes. I believe this ensures the pipes are positioned correctly and flush to the thermostat. Have you checked these?

Whoever did the job, did they clean all the mating surfaces properly?

Hi VBM, I see what you mean about the nubs and slots. They all seem to be in the right place on the thermostat...

Hi Verbout, I took it to A for Alfa who's a specialist and did a really good job. I presume he did give it all a clean... I'll have to speak to him tomorrow
