uprated sprint radiators

[tangocharlie1]

Can anybody tell me the main difference, between the standard sprint radiator and the "uprated one" i have been told i have a uprated one, is there any external difference or markings (PART NO.) which would make it possible to identify the one i have. thanks guys <!--EZCODE EMOTICON START : --><img src=http://www.ezboard.com/intl/aenglish/im ... ohwell.gif ALT=":"><!--EZCODE EMOTICON END-->

In a nutshell.....no!<br>
<br>
Basically you need to count the rows and fin density within the core to determine which you have.<br>
<br>
Some folk think an 1850 rad is a standard Sprint one and the Sprint one is therefore uprated!! I have even heard contemporary recored rads which utilise composite matrix cores (worse performing) as uprated!<br>

this rad and overheating business,can a larger rad off a stag or similer size engine not be made to fit.<br>
a friend of mine used an extra heater matrix alongside the rad on an mg engined mini and it worked!<!--EZCODE EMOTICON START :eek --><img src=http://www.ezboard.com/intl/aenglish/im ... ns/eek.gif ALT=":eek"><!--EZCODE EMOTICON END-->

Yes, the bigger the rad, the more surface area and the higher the heat rejection.<br>
<br>
The other option would be a rad made out of a metal with a higher thermal conductivity like the ally ones used on most Jap cars these days but watch out as some modern rads may have a much higher water and air resistance which may affect the pump performance and airflow through the rad (why some modern cars have multiple fans I guess).<br>
<br>
Mines supposedly uprated and works slightly better than the standard rad, I cant remember how many extra rows there are but its quite significant, about 5 i think.

On the topic of rads, are all the rad mouning points in the same place? i have a 1500 which due to a lack of antifreeze before my ownership had a rotted rad i was given a 1300 one to keep me going and want something bigger as the temp gauge wonders up when i cruise at speed, was thinking about an 1850 rad, Many thanks

The 1850 rad is totally different in design and flows side to side and has 3 hoses. IIRC the 1300/1500 one flows vertically and has only 2....One from a Herald or Spit may be more likely?<br>

Using a Sprint or 1850 radiator is possible on a 1500. The bodyshell has all the right mounting points.<br>
<br>
I used an MG Midget thermostat housing with the water filler plug in it and used the third pipe from the "cold" tank of the rad as the link to the expansion tank. Works a treat!<br>
