air to oil coolers
i hope this doesnt post twice i tried earlier but it didnt come up ill try to say the same thing
this is my first post on here
a little bit of info for you all, my personal truck has the water/oil cooler on it with a homemade coolant filter.
i rarely see delta above 8* from start up to towing usually during normal driving its between 0-5*.
i also have two trucks that i take care of that have two different air/oil coolers on them, one looks like its a homemade system with a thermostat, but im sure its a purchased product knowing the owner.
the other is from a very repuitable company with the cold weather kit
i am not going to mention any names as i dont want to offend any one here and the post is only info i have gathered in real world use
i have had a chance to drive these trucks for a week each both work very well, the complaint i am getting is the trucks are slow when cold (not missing or stumbling)less than120*ect
what i found on both compared to mine is that on startup the ect and the eot
are within 1*on start while warming there is a great deal of delta compared to my water/oil system so now i know it takes longer for thier trucks to warm the oil and i have something to tell them.
after finding this info i have a couple of questions for the gurus on here
1. do the aftermarket companies rely on the block to warm the oil on startup that is being warmed by the coolant?
2. if so then it raises the question do these engines need a cooler at all, based onthe warm up theory it should do an equally go job cooling?
3. we all know startup is the hardest time on the engine so if the engines are taking longer to warm is there more damage?
water/oil coolers are nothing new they are used in aircraft, f1,and many industrial applications because of its consistancy and they have unlimited money
let me know your thoughts and if anyone else wants to monitor there warm up times it would be interesting to see how it differs in different climates we are in ontario canada its been around 0*here 32f for the americans
i know there are some very smart people on here thats why i joined this site
