Something to take note of here in regards to engines failing from overheating. I have a hard time finding a viable used radiator in yards. They all fail in the same place - the forward facing section of the top radiator tank where the hose is connected. If you go into a yard and you're looking for a radiator, check this place for a crack in the plastic tank. This happens as a result of the coolant level not being maintained and the radiator inlet being bombarded with steam and hot air instead of cycling coolant. The plastic becomes stressed and loses it's integrity, then cracks. If you want your radiator to last (and your engine...) check your coolant levels in the radiator and overflow tank regularly. The hardest part about this is actually getting air trapped in the cooling system out. I have deleted the coolant feed into the throttle body which has eliminated the highest point in coolant circulation (this is where air is going to be trapped) I ended up undoing the upper radiator mounts and tilting the radiator so the radiator cap end was higher than the radiator inlet, then topped up the coolant (or in my case demineralised water) The small amount of air still in the system would be purged out into the overflow tank once the engine had reached peak operating temperature. As posted previously, I've removed the thermostat and so far it's not experiencing any issues. I am considering getting a complete thermostat manifold and modifying it by grinding out the seat where the thermostat plunger restricts coolant into the the thermostat housing. This will increase the volume of coolant passing through and may improve efficiency (well, theoretically...) I'm thinking about adding the oil cooler for the power steering as well. I have a big OEM transmission cooler from a Mitsubishi that would do the job. Just have to find a good place to mount it
