Suspend the thermostats in a pan of water on the stove and bring them to a boil. Do not let them contact the bottom of the pan. If the thermostats are not visibly wide open by the time the water boils, replace them. Their usual failure mode is to open only slightly, which will cause overheating under power more than at idle. 3.
When did the cooling system change on a Jaguar?
Somewhere around 1988 — possibly coinciding with the introduction of long-life phosphate-free coolant — Jaguar went from the overdesigned drain cock to no drain cock at all. On later cars, it is necessary to disconnect the lower radiator hose to drain the coolant. Wearing a tux is not recommended.
How does a Jaguar XJ-S radiator work?
RADIATOR: The XJ-S radiator is a side-flow radiator divided into a top third and a bottom two-thirds. The coolant coming from the left bank, via the left side thermostat, enters at the top left and flows left-to-right through the top third (it cannot go directly down to the outlet because there is an internal baffle in the radiator).
