Hey everyone, I have a hopefully quick questions about my radiator.
Last night I noticed some steam once I parked at night coming from the front of my radiator. The steam did not smell sweet and I was not driving through any rain, precip, puddles etc. BUT, sometimes I can smell sweet coolant but I figure it is stuff still burning off. I lost about 2 bottle fulls late this summer when my cap went twice causing it to overflow. I can still visually see the antifreeze on a few portions of my engine bay (ONLY from when it exploded, I have a visual memory and when I check these spots they are not from a leak)
I have not seen any leaks and inspected for cracked hoses but all are well. Also, my coolant level has been steady. The only thing I can think of is that with me using my heat more and more now, I am circulating air potentially through the system and maybe I need to burp it again?
Thoughts? Or because it was about 34 degrees when I was driving, there is just a chance it was steam from a hot engine like steam from your breath.

My engine just recently started up the same issue. Smoke coming from the front right portion of the radiator. Almost by my battery. I cannot find any leaks, but the coolant smell is strong. When I first noticed it there was coolant around my fan. It slowly went away after a couple days, and I thought it had overflowed and burnt off the coolant, but yesterday it started smoking again. I'm curious to see what kind of answer you get. I was going to pull my radiator but I'm not sure it needs to be pulled.
As long as your coolant temperature is staying around 200, you shouldn't have to burp it again.
Any antifreeze that was on the engine from late summer should have burned off long ago.
I think you probably have a small leak and you just haven't found it yet.....keep looking as small leaks can turn into very big leaks quickly and then you'll have bigger fish to fry. For leaks, I usually get the vehicle up on a hoist and get a very good light on it and perform a thorough inspection for clues of leakage.
You have an 88 which has a "heater control valve". They can start to leak when they fail and they fail pretty frequently. I would start by inspecting that valve very closely.
And watch the coolant level closely until you find it.
