Towing with Spartan 250 issues and questions

[Redram99]

So I have been towing with my spartan on 250. Mileage and drivability has been great. I used to run on the standard 210 but the mileage is much better on the 250. I have been getting about 13mpg.

Also, even with the 250 tune the egt, water and oil tems stay much cooler than the stock no dpf tune.

The other day I was towing and had some issues!!
1)my lower intercooler boot blew off and I lost the clamp. I tried to reattach with some zap straps but they would not hold. I ended up using the hose clamp off my sewer hose on the travel trailer and limped it to town.

2)while operating on the improv hose clamp, I decided to run stock no dpf to try and reduce the strain on the system. While pulling a hill my engine water temp spiked to 228deg but my oil never exceeded 210. The fan cut in and then the water temp dropped back to 215 quickly.(this occured over a 1 min period). I have noticed that my oil is typically 8-12deg hotter than my water when towing. I did not boil over or puke and everything seems to be running ok now. It was almost as if the thermostat stuck closed for a second but the fan kicking on contradicts that. Typically my water temp never exceeds 212.

- I thought i read somehere your oil and water temp should be within 6 deg of each other.

- is there a kit or some way to fix the intercooler boots from coming off?

Tranny temp stayed about 175 deg and increased to a max of 185 deg on the hills.
Outside temp was about 80 deg.

I have to say I am amazed there was no diff in tranny temp between the 250 tune or stock no dpf. Also EGT's are easily managable as well.

Thanks Spartan.

Spartan is amazing tuning.

Just read my message... Sorry to Ramble!!!

More than 8 degrees typically isn't good, but my guess is that your EGR coolers might have flash boiled causing the ECT to get really high. The fact that you didn't puke is a good sign.

As for the boots, I recommend DieselSite boots. I have them and they are great quality in my opinion.

[Redram99]

Is it typically the lower boot that blows off or do the others come off as well?

[08stroker250]

Typically the lower boot.

I blew the upper off several times & I'm stock!

DieselSite has a full kit to replace all 4 boots. It's like $160 or so. I bought it for my truck and haven't looked back.

Thanks for the info! So far the hair spray trick is hold up but I would rather have it fixed right! Sorry for the hi jack!!!

when you put your new boots on. Take the time to clean the IC tubes. A good degreaser and elbow grease will make all the difference in the world to prevent the boots from coming off in the future.

On my last trip i tightened up the clamps a bit prior to leaving. I ran that 2200 mile round rip at an average of 25-35psi and none even moved at bit. But I do like the idea of the aftermarket hoses.
BTW towing 10k with 90 plus ambient temps my oil and coolant never went above the 190's.
