2004 Holden Barina thermostat Sign In

Hello,

Tomorrow I'll be helping a friend out by changing out her faulty thermostat on her

2004 Holden Barina XC04B SED

I just wanted to see if anyone here has experience with this particular job in order to be ahead of any potential complications.

Any advice would be very much appreciated.

Regards,
Kev

This car isn't sold to the US where this site is based so can only go on generalities.


Thermostats are usually under a cover at engine end of upper radiator hose. No clue how difficult it is on this to get to?


First thing though is verify it's needed. Why are you or anyone so sure it's bad now?

Hi,

Thanks for getting back to me. The engine is over heating with no signs of cooling system leaks and a full reservoir of coolant. I ran the engine until it was hot and felt the difference in temperature of the hoses on either side on the thermostat, with the hose after the thermostat remaining cool while before it got quite hot I can only assume that it isn't opening. I have changed out a thermostat before on a honda civic with no problems, but as that had a rubber gasket and the Barina appears to have a sealant applied to it I was hoping to get advice on what sealants were commonly used on thermostat housings and how they are best applied.

Thanks for your time,
Kev

OK - From the US it's hard to get an image or diagram of the exact layout or any specific procedures still.


You are noticing a cool upper hose while engine is running warm or hot so that's a fair clue. Do know than a lot of vehicles are VERY hard to fill cooling systems completely especially ones with the pressure cap on the recovery tank and nothing on the radiator itself which could be very low and you don't know it if that type. Hot air might even pass some and doesn't feel anything like hot coolant - liquid.
As for gasket types or sealers + products used: Paper/cardboard like ones I would just smear some grease on them. It could be a rubber ring only a type that could benefit from a sealer product sold here my choice would be Permatex Gasket Maker + Sealer by name. I would only use the very least amount and let fully dry before installation.


Best benefit is if you are back there again it will remove without any gasket scraping which can both be a real pest or in doing so harm alloys. Most original gaskets do NOT use a sealer unless there's a specific reason for just an ordinary thermostat.


If no cap to radiator on this at all try to figure out if coolant is 100% full, no air now and that from a cold start feel the upper hose with no pressure for some time. Whether it warms or not if pressure is building up fast or not at all there's more to check out as to why.


Some other reasons an upper hose or radiator may not get warm/hot could be a very failed water pump. If suspect you should feel warm heater hoses even with a stuck thermostat with request for max heat. If not, either low on coolant or not pumping.


There are other reasons for overheating that are NOT a thermostat but this might be. While there a great time to flush out whole cooling system for new correct antifreeze and water mix.


The part to always watch out for is that it's really full and knowing it. It would quit overheating, heater would work fine and never reach a hot warning by gauge or light. Fan(s) would come on as designed by car maker which may be over the boiling point as pressure systems do NOT boil at higher temps while pressurized.


All of this in short: Make sure it's full when finished and quits overheating to know that was the whole issue and not more involved,
