I know over the past few days its been lovely and hot out. But my water temperature after the engine has warmed up is constantly between 90 to 97 degrees ( regardless of the weather ). Having seen some recent posts I am begining to realise that maybe, this is a little on the hot side.

So I thought its high time I checked the coolant level. Now according to the handbook it clearly shows the aluminium bottle ( as indicated in yellow ) and it should have a blue cap. As you will see mine has a brass top. But there is a plastic bottle ( Orange arrow ) with a blue cap and when I undo it. It smells like coolant. Where should I be adding water if needed?

They are both coolant, remove the brass top and make sure that water bottle is full, then open the blue cap on the expansion bottle, if i remember rightly you only want 1-2 inches in the bottom of that to allow for expansion without pissing steam up out the vents and temporarily blinding your view of the traffic in front.

also check both fans are coming on.

The long tank is not the expansion tank. The expansion tank is the one with the blue cap on it. The long tank should be full, the expansion tanks should have no more than an inch or so of water in it. It will reject anymore than that.

I don't know why I said there is a plastic bottle with a blue top. Because clearly its a aluminium bottle.The heat must be getting to me!wobble

As for the temperature, both fans are working. Maybe I need a new thermostat?

Anyway, Cheers Guys, thats put my mind at rest.

If she goes one fan, two fans, no fans she is working. 90 - 97 in this heat sounds fine. The indicated temperature isn't going to be all that accurate anyway.

Temps seems fine. Also, did you have your AC switched on as this will up the temp a few degrees.

Cheers. Lee.

I drove my Tuscan in the heat yesterday, as soon as I drove into built up area 30mph zone the temperature rises from low to mid 80s to 90 - 91. If I have to stop then the temp goes to 92 hitting 94 tops and fans kick in and its not till you get on move again over 30 mph that the temps really start to fall back down.

Its especially noticeable after giving the car a blast and then hitting slow moving traffic. Your temps sound about right.

This has caused me some serious head scratching which has involved replacing every coolant part and using a vaccuum pruge tool to refill the coolant to avoid any airlocks. I came to the conclusion that its not a volkswagen and you can get some serious temps under the bonnet. As long as both fans kick in and dont stay on forever its probably running fine..
