Got a quick couple of questions

1. is there a higher rated water pump out there for the 7mgte or is the stock one sufficient.

2. Is it safe to use a higher pressure rated rad cap (blitz)? What i have read from Reg is that only the factory one should be used.

3. does many people run additives to there cooling system (redline water wetter)?

All a high pressure cap is going to do for you is raise the boiling point of your coolant, but you shouldn't be running that high of a temperature also. It puts extra strain on old rubber hoses, but if you have hoses in good shape you can run a high pressure cap. Just for S&G I put a 18psi cap on my car for a few weeks, didn't notice any change in temperature, EGT's, or anything. I went back to the stock pressure cap.
