Running hot, Rubbing & Steering!

Re: Running hot, Rubbing & Steering!

The viva rad is definetly adequate when it's working properly - I've proved this driving to the south of France with a fully loaded trailer!

I'm now thinking that the running hot may be just down to the rad - the car did the same when it was being Dyno'd the other day when front wheels weren't in the equation. The mechanic also didn't think the steering was to bad all though some bits needed greasing.

Hopefully I should get the new rad soon and then we'll see. Now, the Dyno brings me onto another thread...

Re: Running hot, Rubbing & Steering!

I think without doubt on of the most important things is to make sure all the air goes THROUGH the rad. and not round it. My electric fan is on the engine side , between the rad and the steering rack. Keep it to the top of the rad. as this is the hottest part and will benifit most from any cooling help. Having said all that, our fan seldom cuts in except in slow speed,heavy traffic situations.Perhaps these pics. may help.

The Austin 1800 rad is a four row radiator which has more cooling capacity than a thin one.

Success! I hope. It's not very warm up north today but my car seems to be running at normal temperature even at motorway speeds (well, Marlin Roadster motorway speeds!)and without any additional cooling from the electric fan.

I took my old viva rad to a local specialist who, once he had seen it, wanted ?120 to recore it with 3 cores. However he let me look through his stock and I found a new old stock Austin Maxi unit which has 3 cores with much closer fins and is 3" taller and 2" narrower than the old unit. He was confident that this rad would cool my engine and for ?40 I took a chance.

Fitting was relatively easy but took a few hours due to needing to remove the bonnet, nose and light bar in order to take out the old rad. I had to modify the rad brackets and fit a new top hose using convoluted hose from Partco as the top inlet was at the other side of the new rad. The bottom hose was still able to reach the bottom outlet even though the new rad sits level with the bottom of the chassis crossmember.

Now, what's the next job on my list?

How did you go on Chris?

Re: Running hot, Rubbing & Steering!

Did pads (again) this time with new anti-rattle shims, made it worse. This was sort of good in a way as it finally showed up the actual culprit which was the brake calliper intermittently sticking.

This is being changed at the moment so hopefully that will it?at last!
