Hi Guys Again

Just a quick question I want to ask.

I brought a new 3 core radiator for my VL Commodore (mine is auto).
I had a cracked head for the second time so partner re bulid my motor. So he read get a 3 core. So got 3 core but just that the temp goes half way. Im worried about that, as before it wouldn't go that high. Has coolant in it and have replaced the themostat in it. But still runs half way. I brought the radator and partner put it in the car. He says it doesn't get hot, put hands on the hoses and doesn't get hot. Only been in the past 2 weeks!

Worry or not?

has the system been bled properly?? If there is air in the cooling system it will read high temps, & can cause damage.

Some motors can run a bit warm when just been rebuilt(tight clearences) and should get better as it's run in more.
Also when you've done 500km throw out the oil 4 sum nice clean stuff and oil filter too!!:thumbsup:

if you dont force water in until it flows out of both bleeder bolt holes the head will crack again

Did he use an aftermarket thermostat?

Get it checked by a radiator place, mine runs on half, and got it checked and it is at 85 degrees.

Standard temp gauge will move quite lot when there is only a few degerees difference.

nothing to worry about, genuine thermostats run at about a 1/4 on the temp guage whereas the aftermarket ones (eg dayco) will run at about 1/2. just make sure the cooling system has been bled properly
