Hi, just wondering how often the coolant should be changed for the V6 engine GTVs? and what's the procedure (novice here)?
I think there are some hex drain screws for the heads on the V6. I dont know where either though.A relatively simple job really, just a shame there's not an engine block plug to allow you to fully drain the system (unless someone knows otherwise?)
Not sure about coolant amount, but thermostat is on RH side of engine, between the intake hose and a black plastic box with cables it. You’ll see the coolant hoses going in.Thanks for the info. Few more questions before i get stuck in....
Mine is 2001 and was orginally a 3.0 V6...but then had a replacement engine from a 147 GTA - so now has a 3.2 V6. I have no idea if the radiator would have been changed though.
Sounds like I should be using red/pink coolant then?
How much coolant should be used?
Where is the thermostat located?
How do you work out the amount of coolant you need? And where do you get de-ionised water from? So once drained, no clean water from the tap?Blue antifreeze should be changed every 3 years and red every 5 years. On my Twinnie (same radiator I think) I removed the blanking plug on the rear left of the radiator draining as much coolant as possible. I refilled with clean water, ran til the fans kicked in and allowed to cool then repeated a couple more times. Work out how much undiluted antifreeze you need and add that topping up with de-ionised water. Check after a day or so and top up if needed.
The handbook should give you the coolant capacity. Antifreeze can be bought ready mixed or concentrate. The ready mixed is fine for topping up but no good after draining as a fair bit of water will remain in the engine block after flushing. The concentrate needs diluting 50:50 so equal amounts of coolant and de-ionised water. For my Twinnie the capacity is 8.4 litres so after flushing, I added 4.2 litres of concentrate and topped up. You should get de-ionised water at any car spares place, even Halfords or even some petrol stations.How do you work out the amount of coolant you need? And where do you get de-ionised water from?
