Hi Guys,
Apologies if this question has been answered before, I have been looking for an 80 for a while and finally found a 93 with factory lockers and 165,000 documented miles. I am a complete noob when it comes to these trucks but I am learning through the articles on this site. I took the truck to the Toyota dealer today to get the coolant flushed, I figured they would know the correct type. The dealer flushed and filled with the red type. Is it ok to use the red type in a 93 LC? I thought the 93 came from factory with the original green type but I'm not sure if it's ok to run the red type for this year.
If any of you guys have an opinion on this or information to back it up I sure would appreciate your input.

Hi. I'm not an expert but I have a 94 which experienced overheating problems back in July while I was visiting my son down in Washington DC which caused me to do a roadside removal of the thermostat along with a new thermostat install a few days later. Altogether I wound up adding 2 and a half gallons of the orange antifreeze from a local auto parts store. Several months later and I've been through blistering heat and bone chilling fredges. So far all has been fine. System seems to work perfectly and coolant still looks clean.
According to the 1993 owner's manual, it just calls out for ethylene-glycol type coolant. This is available in both green and red / orange. My understanding is they are both ethylene-glycol based, but with different corrosion inhibitors. You should be just fine. However, I don't think you are suppose to mix the two.
Red is the only coolant color I've seen put into my 80 series by a Toyota dealership or sold to me at the parts counter. AFAIK there are a few different Toyota "Red" coolants but IME the dealership has a chart to refer to when installing or selling coolant.
"Red" was the factory fill. Toyota has never used green as a factory fill. Orange is GM Dexcool, I would not run that.

Green is fine and if you choose to run it you should flush the entire system, including the engine block and both heater cores.

The key is not mixing coolant types.
Thanks for the quick responses guys, I appreciate the help! I need to find the FSM for the 93 although I'm not sure where to get a downloadable version. There are a lot of bogus sites out there claiming to have it at cost. I don't mind paying for it as long as its from a reputable source.
Thanks for the link Kernal!
