Hi folks , summer is here and it’s raining roll on the drought !
At work I have been asked to make a detailed diagram with explanations of a typical cooling system. So , with that in mind , what better car to base it on but the Stag ,and get paid to do my hobby . When this is finished I will post it for discussion with the expectation that between us we can establish correctly and conclusively :-
Where the coolant flows .
What and how the components should operate .
Short comings in the system .
And last but not least what improvements can be made to update the system to cope with the car’s age and todays driving ..
In starting this project I realised that to complete the full system I think it would help to include the head gasket , and the cylinder head with details of where and what goes wrong and what areas to pay special attention to in order to reduce the risk of further problems .
I am therefore appealing to to all of you out there that have replaced you own head gasket or have had someone do it and know the answers , to contribute your gasket \ cylinder head details so they can be collated into “ USUAL FAULTS” . Hopefully one or two of the garages that advertise in the mag could also give their findings . I hope this will give a more accurate idea of our system in its completeness .
I would like to know :-
A / age by registration --- this will give an idea of engine modle
B / engine number --- this will give an idea of engine spec.
C / mk 1 or 2 inlet manifold --- mk2’s have the thermostat with the stat bye pass disc attached to the
bottom of it .
D / did the head gasket lift off or was it well stuck – to the point that most of the gasket had to be
scraped off the faces .
E / did the gasket have any obvious blow or burn through areas – if so where abouts ?
F / if you records show , how long ago , in both time and mileage when were the gaskets last replaced ?
THE CYLINDER HEAD
G / did it have any loose or moved valve seats – if so which cylinder number /s and which valve .
H / did it have any loose or moved valve guides – if so which cylinder number /s and which valve .
To start this off my head gasket of a few months back was :-
A / K reg Jan 1972
B / engine no --- LF10186 HE BW
C / mk1 manifold
D / the head gaskets were not stuck at all , they looked as if they could be used again .
E / the gaskets had no obvious blown area .
F / the gaskets were last replaced in Sept 1978 , 25156 miles ago .
G / all valve seats were sound
H / no 6 exhaust guide had moved and was replaced with an over size guide .
Many thanks to all and especially those that contribute .
