Why does the Toyota MR2 have a coolant system?
The MR2, in common with many other mid-engined cars, has a more complex coolant system than front-engined cars. This is primarily because the engine is in the middle and the radiator is at the front. Hence there is quite a lot of piping, and the system needs to be bled correctly to prevent airlocks and subsequent overheating.
What should the torque be on a Toyota MR2?

What should I do if my car coolant is bubbling?
Potential radiator damage. The fix: When flushing the radiator and cooling system, make sure you run the engine with the pressure cap off for 15 minutes after refilling the system. This will bleed any air from the radiator and cooling system before you replace the pressure cap. Read our comprehensive guide on how to do a coolant flush.
