Title: COOLANT HEAD TANK CAP
Post by ColinE on Apr 14^th, 2007, 5:54pm

Hi Guys
Before I destroy it, when I took the cap off just the screw cap came off leaving a section in the top of the tank, I take it the cap should be fixed to this so the whole lot comes out, any thoughts please.
Does any one have a spare cap I could purchase, I think I need to get a cap before trying to remove this, is it just a push fit into the tank, then tightened with the cap, I have had a dig at it, it does not seem to want to move. Thanks

Colin

hi there

sounds like the pressure relief valve has been left behind. :-/ it''s a push then screw fit.

i'd go for a new one as there was a design change during production.

On this subject, does anyone have details of the pressure caps for the various models.

I have a 1996 Cosworth and a 1995 2L 16V. I suspect that the caps have been replaced and they do not have the correct pressure ratings.

Hi Guys
Got a new cap this morning the Ford dealer had it in stock, the two numbers on the invoice are F 1029727
504101 Cap Ass £8.80 + vat 10.34.
Broke the old one getting it out, there were two O rings on it, it appeared the top one had stretched and buckled
back on its self cause the cap to jam up, the new one only has one O ring at the bottom, hope that is correct.
I asked the guy if he wanted the chassis no, he told me the year was gooig enough.
Hope this may help some one, I have smeared silicon grease round the new cap before fitting it.
