Hot on the gas
2013 3.5 ecoboost, truck is new to me. Towed car hauler first time yesterday, truck as far as power did great, but under load pulling small uphill grade temp would rise very quickly. Crest hill and temp would drop back to normal very quickly. This would repeat every grade at times as far as pegged in the right of H but then right back down. Pulled over on first time to check under hood temp back to normal within 30 seconds. Limped home,allowed to cool,checked fluids,both engine temp fan and ac fan working ok. Radiator and inner cooler appeared clear. Any thoughts or experience highly appreciated.

- Fuel octane. *(owner's manual excerpt) "Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow."
. - Clean the MAP sensors. The EcoBoost has 3 MAP sensors ....
- How many miles are on the spark plugs? *If unknown or over 60,000 miles consider replacing them.
. - Consider installing FoMoCo's desert transmission cooler......
(owner's manual) Don't have one -OR- would like a digital, searchable desktop document?
