Hi there have a leak from what looks like the thermostat on the rad (On the right as i look in the bonnet).

Is this the common leak ive read about and what normally needs replacing Im hoping to get the bits before I start the job.

I'd advise to do the lot, as you can gurantee you will damage another seal taking it apart or putting it back together, or it will just leak from anoter seal instead.

Hi there have a leak from what looks like the thermostat on the rad

The thermostat is not on the radiator' date=' it's on the bottom right hand side of the engine block as you look from the front. It should have 2 or 3 plugs/connectors going to it (depending on air-con)

If it is as pic above then yes very common leak, replace the lot as suggested

If it's not as in the pic above and actually on the right hand side of the Radiator, then I guess it's the Fan switch

Discovered at lunch a little get of water coming from behind the top of the fan housing.

Now worried I have a small leak on the rad.

Went to price up a rad change at my local garage and they have suggested Wynn's "Cooling system stop leak".

They swear by it and say it doesn't clog the system.

I'm not sure about this but may try it on my 306 with a leaking rad first.

Just wondered if anyone had used the stuff

Or alternatively anyone got a spare rad or know what price I can expect to pay for one.

my motto is never cover a problem up, fix it. you can pick 2nd hand rads up cheaply enough providing you know it's a sound unit, or you can get one from GSF presumably, which you get 10% discount as a premium member.

Found somewhere doing them delivered for about £65

And my local garage will fit it for £35/hour plus vat so its tempting

If you've got the money, and you care about the car then fix it properly.

The radweld might fix it for a while but what if it blocks something else that it shouldn't. or it starts leaking more when you need the car most.

just my opinion mate, but good luck with it

I paid 90ish from gsf and fitted myself. not a hard job, whip the bumper off and that 50% of the job done. Good luck mate

Well had the rad fitted on Friday.

what a relief not having to constantly having to check the coolant level.

have done about 300 miles mostly motorway with some back roads in Cumbria including racing a TDI until the gf shouted for me to stop

Well to the point £130 alll in and it's the best £130 I ever spent on a car.

Just the ABS to diagnose now oh yeah and the Chains to change next weekend.

lol
