Well wasnt going to update this thread but im going to attempt fate, as the project should be kept up to date good or bad. So heres a quote from another of my threads explaining my problems.

 

 

Hello all I'm going to keep this as brief as possible but explain everything I can so here goes bare with me...

 

First the car in question is a NA 5 speed.

 

During Dragon ball the car suffered with over heating when going over 60-65mph causing increased pressure in the rad hoses and vacuming of the top rad hose when it cooled down. This also caused the water to be pumped into the expansion tank causing it to fill to the brim along with it pumping air into the tank too. I had to keep speeds low and heater on to keep temperature at half.

 

While I was on DB I got a new rad cap from another member and after 30mins driving it soon became apparent this had not solved my issue.

 

So on return I had the water tested fro HC's and it came up zero so this would suggested the head gasket is fine(this has now been done a few times to be sure), so we removed the thermostat to see if the problem stopped but everything continued.

 

After talking with the garage my viscous fan was not working at full efficiency + having spoke to keron he suggested it could be water pump issues. So it had a new OEM water pump, new OEM thermostat and second hand, but fully functioning viscous fan/clutch. Still no improvement.

 

So next we check the heater matrix by removing the top hoses at the back of the bulk head and pored water into them and it flowed nicely so this has me thinking this is not the issue.

 

We also flushed the system through many times to remove blockages and all seemed fine.

 

Next we tried to bleed the systeme again by jacking the front up as high as possible this seemed to work and lots of air came out then all of a sudden the car coughed, and idle started to bounce by about 200rpm and when taking up the road it was missing.

 

Took the car back asap and left still for about 30mins and fired it up to move into my drive for the night and the miss had gone and idle was now fine.

 

The next day I put another brand new OEM rad cap on, and result!! when driving, even heavily the cars temperature stayed bang on! No expansion tank issues, vacuming etc all good, temp nice and steady.

 

Now this is where the fun begins...

 

I took the car away on Sunday and all was well, until I pulled onto the Motorway, ten mins in at 70mph the temp started to rise, pulled off to check the expansion tank and all was fine under there, but car was still getting hot. I drove the car the whole trip and as long as its under 60mph the car seems fine, temp good, expansion tanks good etc but as soon as i get near 80mph or go up a long steep hill the temp goes up.

 

Im now stumped as to what it can be, as the problem is now allot better as the expansion tank is fine, the coolant levels are staying nice, no vacuming, but the temp only goes up and high speed or when the engine is under load,

 

The only thing i can think of is to get a new rad, an other ideas at all guys?

 

I'm getting a bit sick of this now.

 

Following from this I have gone and bought a new rad which is on its way as we speak, and is going to be fitted saturday. So wish me luck guys...

Well im glad that I wasted my Sunday doing the rad. The piece of rubbish doesn't fit at all, all the fittings are out by miles.

 

So i will be sending it back again and getting a SRD, wifbitz or OEM one now.

 

Got a picture of the bay stripped down before all the fitting fun kicked off, then i wasnt in the mood to snap pictures.

this is the ebay "cheap" one ?

 

Thats correct, even though I have been told they are the same as the traders ones, after this I'm sceptical. This is the first mechanical part I have bought which has not been OEM and sure enough no end of problems. Should have known best really, I was just attracted by its shiny finish.

Really? But you love bling and an oem one will actually be more monies!

 

I thought this too but Chris Wilson has sorted me out an amazingly cheap price, plus fed up with the non genuine fitment issues.

 

Feel free to drop me a pm, of the price of yours for me to consider.
