For as cheap as you can find an OEM replacement. I would say no. However that really depends on what they would charge.

Re: LT5 Cooling and Radiators
So is it even worth cleaning the radiator fins at all or just replace it since you have it out?

Re: LT5 Cooling and Radiators
Are these available anywhere or discontinued?
Im a little of dropping it on the pavement to get anything out as the plastic on the ends is joined somehow to the aluminum and I don't want to risk cracking any joints considering its been heat cycled throusands of times over 20 years. I will be pulling it out for sure and im fairly certain with 75k miles it wont be clean as new. I don't have any cooling isues besides the one hot day we had where I was parked with the a/c on I noticed the temp right at the warning zone. As soon as I turned the ac off it dropped and as I got on the road and to 40-50mph it dropped really fast. I am going to take a guess that based on what Ive seen one side of the rad will be jammed up very well most likely ahead of the primary fan. Ill be doing a spray soap clean and garden hose approach with no pressure and a soft bristle brush I purchased last night to try and get gunk out between the fins without bending anything. I shall report back !! |

Re: LT5 Cooling and Radiators
My opinion only, maybe not the post you're hoping to hear...
I didn't weigh them when I swapped. but my opinion is the difference in weight is nothing any of us would ever notice. I mean, you could toss them both in the air pretty easily. A tiny fraction of the weight of the car. However, I suppose it's possible a 4 core radiator might hold more coolant, and therefore might add a little weight, but again, negligible. I was wishy-washy about changing mine, weighing the pros and cons, and eventually decided if people like Marc Haibeck recommends the Dewitt, might as well do it and (hopefully) solve all cooling issues and never worry about it again. I will say, though, that even though the Dewitt is considered a "drop in", it still required some extra work to get it in. I'll elaborate if you want to hear. |

Re: LT5 Cooling and Radiators
U may find that the fins bend even using a soft bristle brush. It doesn't take much.

Re: LT5 Cooling and Radiators
Maybe but it is exceedingly difficult without bending the fins. I would not even attempt it unless money was a crush. After 25 years it's time for a new radiator

No idea on the T-Stat. I said tap not drop. Your talking about A 20-25 yo radiator and you are correct the plastic ends tend to swell over the years. Just order a OEM replacement they are fairly cheap.

I have ideas of running coolant under the car and putting a rad where the spare tire is and directing air to cool it from there ! Would take a good 20+ lbs of a rad and coolant at the nose end and put it over the rear wheels or close ! |
