Hi,=20
This isn=E2=80=99t the usual one ....=E2=80=9Dmy car always runs hot; what=
=E2=80=99s the cure?=E2=80=9D etc=20
No, this is my very own original.....=20
Background:-=20
1) The car, MkII BT7, has never had overheating issues before today.=20
2) It has a new, 12 month, modern design radiator.=20
3) It has the correct type(original design) Smiths sleeved thermostat. (5 y=
ears old +/-).=20
4) The waterpump was in the car when I bought the car +/- 25 yrs ago.=20
Today=E2=80=99s symptoms:-=20
1) I took it out to the pub today and, on returning, I noticed that there w=
as HEAT and then that the gauge was off the scale.=20
2) There was plenty of coolant in the rad and it didn=E2=80=99t seem overly=
hot.=20
3) I didn=E2=80=99t have much time, but I got the impression that the rad w=
as not blowing steam or making more of a =E2=80=9Ccooling-off noise=E2=80=
=9D than usual.=20
4) I also got the impression that the engine was hotter than the rad.=20
Is this typical of a failed water pump?=20
How can one differentiate between thermostat issues and waterpump issues?=
=20
Any ideas?=20
