Vitara 8V nearly overheating

<< < (2/4) > >>

Evilgoat:
See up. Sure someone else will come up with an idea.

LP32:
Update: Did the water top up when I got back yesterday and have taken it for a run tonight, only 5-6 miles but gave it some pain and it was at temp, no heater on and no overheating and after turning off no bubbling sound? could it be a sticking stat? re the rad being hot yesterday it could just have just been warm? never realy took much notice I was just thinking how the RAC would get there to fix it

Might be. Off the top of my head I dont remeber where the stat is (must be old age as I was under the bonnet this afternoon). Might be worth taking it out and checking it, dropping a new one in if its not too many pennies. Problems with fuel and ignition can cause overheating too.

StuartL:
Get the hose pipe on the radiator.  As I found out the radiator can conceal quite a lot of crud you can't see when it's on the Vit.

Get a low pressure hose, take the rad grille off, hold the hose close to the rad and slowly work your way across it.

If you feel confident (or have an infra-red thermometer) you can deduce where the cooling system is failing by following the water heat patterns around the radiator, water pump, manifolds etc.

I've just been through all of this, if you need a hand just let me know!

LP32:
Thanks for the response. after the initial problem I can't make it happen again so have changed the stat anyway. If I do get a repeat I guess the next step will be the rad. I can get hold of a IR thermometer so might just have a play anyway, when you did this how much variation did you get when it was running OK. Thanks
