Re: The long road to V6 turbo AW11

So I put the AW away for a bit as I was getting sick of it. And I started work on the Rav mud buggy.
Glad I did because I guess I needed time to clear my head. I couldn't figure out why a reasonably new water pump would just stop pumping. And I was dreading the job anyway So I started further investigation. 1st point. 3VZ uses a bypass thermostat. So removing that probably only makes things worse. I tested the old one in boiling water and it seemed fine. But for peace of mind fitted a new one anyway. I also discovered with the cap off water quickly overflows out of the engine. And also the bleed on the top of the radiator has suction when the engine is running. Stop the engine and water pours out.
So, I started to wonder if there was a blockage somewhere? What area could block that easy? And why? The radiator perhaps? So I disconnected the hose from the engine to the radiator.... Perhaps it was this?!!
I couldn't have imagined this happening either though to be fair!
This is an inner lining of my radiator hose. The one that blew off. I refitted it in the car in a very awkward and hard to see spot. (Between the alternator and fire wall) Instead of removing the full section. I regret this now!
So it seems the inner lining came loose and blocked the end of the hose joiner!
Now, I probably should have replaced this hose. But its Sunday and I did managed to trim that end down okay. So far so good! No overheating. (Yes that may also bite me in the arse later, watch this space)
But fingers crossed I can go back on to mods now rather than repairs!!!
