What do you add when coolant is low?
If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water. When the coolant rises to the cold fill line, replace the cap and tighten it until you feel it click.
Why does my Jaguar XK8 have a low coolant level?
If the level doesn’t change with RPM and the stream is bubble free then the header tank filler cap may be faulty allowing pressurized coolant to blow past when hot and into the expansion vessel. This lost coolant won’t draw back into the engine when it contracts and cools – hence the lower level.
What’s the low coolant level on a 1998 XJ?
1997 MY-ON XK8 Range 1998 MY-ON V8 XJ Series 001001-ON 812256-ON MODEL VIN Low Coolant Level – Warning Lamp Illuminated Issue: When a new vehicle is factory-filled with antifreeze solution, small pockets of air may remain trapped in the cooling system.
Can a Jaguar XK8 run with the header cap off?
When the engine is run with the header tank cap off there are no bubbles but, regardless of everything, after 5 or so miles, the light comes on, I release the pressure and it goes off. I then can drive for 20 plus miles with no problem.
Why does my Jaguar XK8 go off after 5 miles?
It’s been pressure tested and there is no indication of water in the oil or oil in the water. When the engine is run with the header tank cap off there are no bubbles but, regardless of everything, after 5 or so miles, the light comes on, I release the pressure and it goes off.

How often does the XK cooling system need to be replaced?
To maintain the long term reliability of the XK cooling system, it must be periodically flushed, the thermostat must be replaced, and new coolant must be added. This document gives some information on coolant type and flush interval, and pictorially shows the step by step coolant flush and thermostat replacement procedure.
When did XK coolant version 1.1 come out?
July 9, 2010 – Version 1.1 Removed references to specific forums. Removed some “opinions” on coolant type that have lost some credibility. Made a bunch of clarifications. General Information I will give my opinions on coolant type and flush interval below.
What’s the cooling system on a 2000 XKR?
The procedure and pictures are from my own 2000 XKR. The procedure for other XKRs is the same, as far as I know. However, XK8s have a substantially different cooling system due to the absence of the supercharger intercooler. I have marked steps that should be omitted when flushing a normally aspirated XK8 engine with a (***).
