Thread: Fuel Cooler Removal Td5

Salt - not good....

Interestingly the avg max temp for your region is only recorded at 33°c

Aside from your high humidity, I wouldn't say that's particularly high... Hence why your fuel runs the temps it does.

Unsealed roads likely help as little reflected heat...

Over here it's regularly over 40°c in summer and reflected heat from roads at over 60°c.

I took some temperature readings with K type touch temperature probe
Td5 running/idling highway and city driving for 2-3 hours
Ambinet temp 36c
Engine Coolant temp ECT at sensor 92c
Coolant temp at fuel cooler inlet 67c
Fuel entering fuel cooler 83c
Fuel leaving cooler 78c
Fuel filter near fuel tank 78c

Conclusion:
Fuel cooler cooling as name indicates
Fuel cooler is bypassed when fuel is cold.
Engine/head/injectors heat fuel till cooler is needed.

That temp is took from our airport, that is located in front of the sea, hence there is always lots of breeze, you always feel good temp around our airport. Why in the hell they put that sensor in there? nobody knows, but I feel this can be a tourist thing not to show so ...

I work in logistics, we check everyday temp inside the warehouse and out of the warehouse (sun reflect). For noon, have never seen under 37°C unless it's raining. In hot months (may, june) we can see 42 inside, 46 outside (affected by sun). This, joining our high humidity, make you want to die when going into my Defender (55° inside in a sunny day).

Is that a normal temp you show? my car is using a/c all the time in very heavy traffic (like the one in the photo) and never goes over 90, doesn´t matter what I'm towing or what the temp in the outside is. Sorry, I was talking about oil cooler but was confused by fuel cooler (that I can see works). The oil analysis (every oil change I do one, they are for free) didn't show change in TBN, calcium or moly after the new piece. OK, they show some change, but sometimes up sometimes down, so nothing significant. Each oil cooler costs USD 700 here in Colombia, so USD 4000 (due to workshop expenses plus new oil, filters and cleaning) is a crazy thing for a bad quality part. That connector costed me 60 dollars and I'm sure it's going to last the engine life (hope didn't cut part of its life, but I have an Euro 3 waiting for a chance to be used).

Also, Texaco Longlife coolant here costs a hand + an arm and is almost not existent in most of the country, and living in a country where my car can get me to really dangerous places (due to guerilla) I don't want to be thinking in a piece that can fail any time and let me in the middle of nothing... In South Africa they do a really good looking stainless steel cooler with a low price, maybe I'm buying one of these to maintain car design, I'm still thinking about it. They have same problem with salt in there....

Happy Days.

Lets not get confused here...

theres things that engineers want to do and things that the bean counting idiots and ergonomicists will let them do. Trust me, taint the same.

I'm surprised this discussion is still going on, If amateur engineers want to change a system, just remember, it must be signed off by a real engineer, and ethics say, don't try to sell it on, without that. Enough said. Bob

So true mate.

Happy Days.
