weather conditions were mid-80's and humid. my 92 dx hatch /B18C1 was cruising for about 1 hour at a constant speed of 75mph. i decied to speed up to go with the flow of traffic. as i appoached 90mph the temp gauge shot up from being a little under the half way mark upto the hot mark but not in the red

So I decided to pull over and check to see if the radiator was in good condition and it was. no leaks, fan works or any signs of malfunction. i did notice that the overflow tank was two inches higher from where i usually keep it. i continued to drive watching the gauge incerase with my speed. i came into a heavy rainstorm and to my suprise the gauages were fixed. there was no more fluctuaition. later that day i drove back home and there was no problem at all.

the only thing i can think of is a clog in the hoses or my radiator is going KA-put. maybe it's time to buy a del sol dual core, any thoughts

 

Prolly your thermostat.

 

You have a 11 year old stock single core radiator that's about 1/4" thick and half the size it should be with a motor that's turning over 4000 rpm consistantly at highway speeds. If you have a hot day, it's not going to be hard to overheat it. The Del Sol radiator isn't a bad choice, I just went all out and got a fluidyne for mine and never had another problem.

 

Stock single core just doesn't cut it on a B series motor under hard driving conditions.

I bought a PWR for my baby.

 

:werd:

i agree with you both, yes it is 11 years old and cannot take too much abuse. in your opinion. would a del sol one have these problems too? i think the del sol dual core is $100.00 from autozone. how much and where is the best price to get a fludyine?

thanks for the tips

 

Del Sol would be a vast improvement.

A better radiator (Fluidyne, C&N, PWR) varies with size (1/2 size, full size), but would typically be at least $300.

 

Yeah, as they said, the stock single core isn't gonna cut it running at a constant load on a hot day for that B-series.

The del sol dual core is the best bang for the buck radiator :thumbup:

Spend $100 now on the radiator to prevent premature failure of your motor.

 

thanks doods

 

a fluidyne in my opinion would be overkill if your motor is not heavily modded,...if you go to autozone and ask for a del sol radiator that is dual core you can get it for about a hundred bucks PLUS a warranty

 

Good tips guys... I think I am in need to upgrade my radiator... I think the Del Sol is the quick fix for now. :goodjob:
