Ohk i have noticed a very small leak where the thermostat bolts to the head, i was wondering if there is a new gasket that you can get for it as my guess is that it has had it?! It leaks from the top of the housing!

not sure what your question is but each time the gasket needs replacing its a good idea to allways replace the thermostat at the same time cos they can sometimes fail to open after a few years.

I have seen this before, its a Porous casting ( or its badly corroded), so you'll have to replace it. Make sure you use a new thermostat seal.

Im not talking bout the Thermostat houseing as such, but the whole square block that bolts to the side of the Head, The bit that you bolt the lid of the thermostat (for lack of a better word) well that bit bolts to the head and it is leaking coolant very slowly and i was wondering if there is a gasket between it and the head?

Yes, ford have replaced the original gasket for a metal one.
When i asked if sealant is needed with it they advised i used a special aluminium paste which was $40 
Its red, smells like cherry and only cures when it reacts with the metal gasket, all the excess that gets squeezed out remains soft & runny. I used the above and doesnt leak anymore. |

Yes there is a gasket avaliable and doesnt have to be from Ford, infact you can make your own out of a weeties packet (smear some grease on the face of the housing face and press onto the brown side of the weeties packet and cut out) then along with some permatex sealant or silastic and maybe a draw file on the thermostat housing face to square it off it will be as good as new without leaks. I know cause it worked on mine and im sure thousands of others before.

yeah its true cardboard works. i used a carboard milk carton and selastic (form-a-gasket). it works well didnt have any problems.

Hi There
In theory a card gasket and RTV / Silastic should work. But I tried twice with this method and a small, persistent leak remained. I went to Ford and got the metal gasket ( about $5 ), and with a little RTV / Silastic on either side, the leak stopped. Whilst the card gasket MAY work for you, I would really recommend getting the metal one to be sure. Good Luck |

If the two mating surfaces are clean, dry and true ( flat ), then you should be OK. Just make sure you let the sealant set for the recommended length of time before starting engine / topping up coolant etc. Good Luck Last edited by gutza on Fri Nov 23, 2007 3:08 pm, edited 1 time in total. |

I got my gasket from REPCO for about $1.50
Silastic or Aviation Gasket Goo would work just fine.

I got a card gasket from Repco and made sure the surfaces were clean and true etc. Used some silastic and damn, a couple of days later, it was leaking again. For some unknown reason the card / silastic solution seems to work OK on some cars and not others. For those of you who haven't seen the Ford metal gasket.... There is a small ridge which runs around the outside of the inner hole of the gasket. This small ridge, I imagine, is compressed when things are tightened up, which may explain its better sealing abilities ??? |

Be sure not to over tighten the bolts as it will distort the mating surface and may lead to leaks towards the centre of the housing gasket.

I use Loctite 515 in a tube. Its an anerobic sealant, it means it only cures when NO oxygen is present, so what squeezes out the sides won't cure.
