Well i know the cooling systems in these cars has usually been able to keep them pretty cool, at least until the W/P goes out. If you're looking for the most performance and cooling effecientcy (spelling) the get yourself an electric water pump. It'l free up some horsepower and will provide constant flow in the motor just like stock. As for the radiator it'* probably good enough to handle anything for he time being, it'* still brand new. I'm not sure how many cooling fans your car has, it may be two but that could have only been on the heavier duty cars like the ssei or something. The real answer for yourself is pop the hood and look.

your rad has more than enough cooling capacity for you. If you want your car to run cooler get a 180* tstat and save yourself some money. The electric WP isnt a very rewarding mod for what you have done to your car so far, I wouldnt worry about it.

This all brings me to a question, And I have wondered this for a long time...

The 87-91 Bonneville with Heavy Duty cooling had a second fan... But was the radiator the same as a regular bonneville( These are all 2 core if memory serves )...

So with the HD cooling, did the bonnie get a 3 core radiator?

I'm also wondering the same for the 92-93 Bonneville with the tow package and or Supercharged... Were these 2 or 3 core radiators..?

I think that a 92-93 with the HD cooling with the trans cooler or the SC with the trans cooler had the 3 core rad. I rermeber seeing 2 different part numbers for the 92-93 Rad

My friend with a GA ( 86 ) had to get a new radiator about 2 years back... we had on heck of a time finding the correct radiator for it... we keept telling everyone that their listing was wrong, and the car had a 3 core... After may tries we finally got the right one, a 3 core to match the factory one he was replacing..

If you are looking for better cooling, go to

www.evanscooling.com

Just adding their coolant is good enough, if you want to really go nuts, they have radiators, fans, smaller coolant pump pulleys, thermostats...the whole 9 yards.

can you just switch to that? I thought even going from green to red was bad because of parts/seals being coated with the old coolant.

I switched to the red stuff in 1998... I still use it and have had no issues... Had a water pump replaced at 80,000 ish miles... Turned out that GM used an Autozone unit... It failed right after the warranty was up... I replaced it 4 years ago... No further issues.. I rarely ever add any coolant at all...
