The pressure inside the coolant system can become higher due to compression gases escaping from the compression chambers into the coolant system.When this happens the coolant system can sometimes keep the radiator hoses hard all night.

I'd be inclined to put a 76deg C 'stat in the bottom - but I think the top stat will still be redundant - unless, of course, you have done something clever to the lower 'stat.

Toyota 120 Prado 1KZ-TE cracked cylinder head As a result of overheating. If your lower 'stat is stopping the flow from the radiator, your top 80deg C 'stat won't make any difference as it will open way before the lower one. Toyota 1KZ-TE Engine Land Cruiser Hilux 4Runner Turbo Diesel Motor 3.0L 4X4. Presumably the system relies on thermosyphon to let cool coolant replace hot coolant at the bottom of the block.

The problem seems to be that the top gets too hot under sudden loads and the bottom doesn't get hot enough to open the 'stat. On the standard set-up there is no restriction to the flow at the top and the lower 'stat is 82deg C. You have an 80deg thermostat in the top and a modified thermostat in the bottom, how has the lower 'stat been modified? ive got 2 temp gauges also modified my toyota gauge to read quickly with new resistors, ive noticed the temp rise up to 90ish from 75 deg C in the head where the factory temp sender is and the aftermarket temp probe in the top hose outlet on 80-82deg C and not move, under quick excelleration high loads ie up hills in 5th towing, could the coolant be that much different?

Now in aussie land the only thing you can get for headgaskets is spray on copper coat, I am wondering if I should get the hylomer blue jointing paste from the UK and use that on both sides of another toyota gasket? Im hoping I dont have a new cracked head, and its just a compression leak around the back of the engine - noticed it was discouloured when the new head went on, it does chugg a bit on one cylinder now on 1st startup for the dayīobMurphy ive read your posts on the coolant flow, I was starting to think if the lower bypass thermostat works perfectly wouldnt it be causing a hot spot in the back part of the engine when the thermostat opens and full flow is acheived, closeing the internal gallery? I was wondering if I had another cracked head if this was the case as my bottom thermostat is in position to keep the bypass closed (wouldnt think it would be totally sealed shut)and allow the top thermostat to control the temp of the block

Hey guys, Im in aussie land, did a conversion on my old 4runner with a 2004 1kzte, came with a cracked head that developed 2 months after install, have since fitted a complete assembled kiwi heads head and a genuine gasket, a 55mm monster alloy radiator, mechanical injection pump, lpg, w2a intercooler, 3inch zorst for some decent horsepower, and it goes really well, problem now if head/block gets over 90deg, (has a 80 deg top thermostat setup - lower thermostat with bypass modified), it starts to pressurize radiator which then leads it to run warm with less coolant in the system, takes around 1200klm to use 3 litres, Have been using water/water wetter instead.
