I have had a 2004 Xtype for two years: last year the radiator sprang a fast leak and this year the ‘return to reservoir’ hose started to leak.
I wonder if this is a sign of combustion pressures getting into the cooling circulation by means of a gasket leak?
How could I check the pressure, if this is a possibility?

 

Welcome aboard Andrew.

 

Welcome to the Forums.

The members in the X Type (X400) Tech Section will have answers.

Might pay to mention what engine, transmission it has.

Plastic and cooling systems, not a good match, and 10 years seems to be average before issues start.

Good luck.

 

Thank you for your message: it is a 2.5 litre petrol V6 with manual transmission and orange coolant added to the water: enough for UK Midlands Winters (-10C {14F}).

 

Welcome to the forums Andrew,

Good to have you with us.

I'd eliminate the simpler (and cheaper!) possibilities of sticking thermostat or failing water pump before going to the level of gasket failure but a cylinder compression test and a cooling system pressure test together should give a you better idea. Once a Jaguar starts needing cooling system components replacing, it's usually the start of a full hose set etc.

I can see you've already found your way to the X-Type forum so there's no need for a link to it from me. The 'HOW TO' thread at the top is a good place to start for information on regular issues. You can also use the UK & Eire Region forum by following this link https://www.jaguarforums.com/forum/uk-eire-68/ to find other members in your region.

Hello, Andrew,
Any radiator is under pressure if only from the water being hot. 16 years isn't a bad life time for the modern Plastic radiators. One might expect to be replacing such Plastic parts before now actually, so you're just about right on schedule.
