The 2010 Jaguar XF premium 5.0 model has had coolant-related problems.

[JaguarLover22]

I was uncertain whether to include this in the introduction; but, I will go with presenting the following information. The 2010 XF model has been in my possession for almost three and a half years. I own a vehicle with an approximate mileage of 90,000 miles, indicating that I have been use it as a primary means of transportation on a regular basis, but this has changed in recent times. Approximately two years ago, I experienced the activation of the coolant indicator shortly after an oil change. As a novice individual and with this being my first experience with a V8 vehicle, I reside in close proximity, around 20 minutes away, from the dealership located in Carmel. Consequently, I opted to drive the vehicle to the aforementioned dealership. Engaging in such an action might be considered very unfavorable. The replacement of the water pump, hoses, coolant tank, and timing belt is necessary, incurring an approximate cost of $4,000. Fortunately, the engine remained undamaged. Whenever a light or any other indicator illuminates, I promptly arrange for the vehicle to be towed to the authorized dealership. Subsequently, subsequent events have been rather favorable. I dare to assert that the subject matter is very remarkable. In mid-February of the current year, the routine annual oil change was arranged and successfully carried out. In early April, the coolant light becomes illuminated. According to current information, it has been indicated that the rate of coolant depletion has somewhat increased, occurring about every 2 to 3 months. This phenomenon is attributed to the advancing age of the vehicle and the resulting heightened workload imposed on the engine. It is possible to get that particular item after the vehicle has reached a mileage of 90,000. However, subsequent to having the coolant replenished, a week later the indicator light reappeared. Currently, my acquaintance's vehicle has remained stationary in the garage without being operated or activated subsequent to the reoccurrence of the illuminated indicator. Upon activating the vehicle, I proceeded to initiate the opening of the hood. The experiment was conducted for a duration of around five minutes, during which no observable leakage was detected in the vicinity of the tank. Furthermore, no anomalous occurrences were noted, other for the personal need of a vehicle cleaning. Upon visual inspection of the coolant tank, it seems that there may be a filtration process occurring whereby the coolant is entering the tank from the upper portion. I am uncertain about how to articulate my observations, but I intend to get coolant on my next visit. However, I am undecided as to whether I should book an appointment and inquire about the possibility of a comprehensive inspection. Once again, a photograph was captured in order to ascertain if the occurrence of the flashing light was maybe an error. Throughout the whole duration that the automobile was operational, the low coolant indicator remained off. The current coolant level seems to be much lower compared to its previous state when it was filled. If my understanding is correct, the coolant level should ideally be positioned just below the line corresponding to the cold air filter. I am interested in knowing if other individuals have had any concerns about the rapid consumption of coolant, or whether there may be an underlying problem that is not readily apparent to me or above my current level of expertise. Thank you for any assistance provided.

Following an extended period of cold-soaking, it is recommended to use a cooling system pressure tester to provide pressure of 1 bar to the system. Observe the tester gauge in order to ascertain if the pressure exhibits a decline throughout a span of about one to two minutes. If such a situation arises, it is advisable to conduct an inspection for potential leaks and afterwards arrange for their rectification.

Presented below is an illustration of a cooling system pressure tester that is now available for purchase on the online marketplace platform, eBay.

Has the engine been subjected to an episode of overheating?

[JaguarLover22]

Apologies, esteemed individual. I was uncertain about how to respond since I am new to the platform. No, to the best of my knowledge, there is no evidence to support that claim. Is there an indicator light that would be activated in such a situation? If an individual has never done so. Furthermore, in the event that you are referring to the revolutions per minute (rpm) reaching its maximum limit, I sometimes use the sport mode when driving on the highway. However, I have not experienced any instances of stalling or excessive over-revving that deviate from the expected norms. I was reminded that towards the conclusion of December, subsequent to the Christmas holiday, I endeavored to get an appointment prior to February for the purpose of expediting my oil change. This urgency arose due to the persistent illumination of the check engine light. Upon doing an analysis, I have determined that the diagnostic trouble codes retrieved from the system are P0171 and P0174, indicating a condition of low fuel mixture. Upon contacting the dealership, I was informed that it would be OK to use the vehicle until my planned appointment, provided that the check engine light remained consistently on. This concession was made due to the unavailability of an earlier appointment slot. In February, an examination was conducted during the oil change procedure, revealing that a hose had become detached, therefore causing the identified problem. Uncertain about the potential relevance of the provided information.

I really hope that your assertion about the alteration of the timing belt is erroneous.
Does your vehicle use chains instead of belts?

Conducting a cold pressure test is considered the most effective method for identifying the issue.
The completed work amounted to a total value of $4,000. However, it is necessary to provide a comprehensive record of all tasks performed, including the corresponding component numbers.
At the mileage of 90,000, some maintenance tasks are required, nevertheless, the engine will not use coolant unless there is a leakage. Engines that are functioning correctly do not deplete coolant.

According to recommended maintenance guidelines, it is advisable to do a coolant change and replace the spark plugs when the vehicle reaches a mileage of 90,000 miles. It is advisable to do regular inspections of timing chains and tensioners. Additionally, have you encountered any auditory indications of timing chain noises? Numerous instances may be found via doing a thorough search. Additionally, it is likely that the SC snout is producing a clunking sound. Therefore, please include the repair of the SC snout and ensure that the SC oil is changed during the snout replacement process. This is an opportune moment to engage in the activity.

If the vehicle in question were under my ownership, I would choose to replace the two cooling components made of plastic, which are known to be susceptible to failure, with the more durable aluminum alternatives that are now accessible and designed to endure indefinitely.
Has the water pump undergone replacement?

[JaguarLover22]

During the discussion, the topic of replacing the engine drive belt arose, with the suggestion that it be done while the components were already disassembled, considering its certain need for replacement in the future. A pressure check was conducted in February to assess the presence of a potential coolant tank leak, yielding no conclusive findings. I have scheduled an appointment for an inspection next week; I anticipate that this arrangement will be beneficial.

Indeed, you are referring to the drive belt or serpentine belt, which is indeed in need of replacement.

It is commendable that you have acquired the most recent iteration of the water pump (identified by the part number concluding with 3909) and have also replaced the front plastic pipes. The coolant tank does not seem to be included in the repair bill. Leaks may occur in metal cooling pipes, however their frequency is very low as compared to plastic cooling pipes.
I would strongly advise opting for aftermarket Aluminum components. However, considering that you have just incurred expenses for the current components, it would be prudent to diligently monitor the levels of coolant and oil.

The image provided does not depict the presence of the two prominent black plastic front pipes. I trust that the Jaguar sent to you was equipped with the revised plastic components with seamless integration. Are you referring to the products that have large, thick welded seams that are prone to leakage?

To determine if the SC snout produces a clunk sound. To disengage the radio when the vehicle is in idle, proceed by opening the driver's door. Please proceed to deactivate the engine and attentively monitor for any auditory indications such as a clatter or clunking noise during the engine's cessation of operation.

[JaguarLover22]

Regrettably. Regrettably. I have discovered. The loss of hope is pervasive. The replacement of the engine necessitates an expenditure of $28,731.39.

[JaguarLover22]

Could you please provide me with any guidance or recommendations? Alternatively, is it possible that my companion cannot be salvaged until the engine is replaced?

[veroguittar]

It seems that the vehicle has had instances of overheating, maybe on many occasions. The user's statement suggests that their post may perhaps convey a similar sentiment. The user persisted in operating the vehicle subsequent to the activation of the coolant indicator.
What is the frequency at which fluid levels are typically monitored?

There are no recommendations available since it is not feasible to operate an all-aluminum engine under conditions of overheating. This phenomenon is seen on a daily basis as well. I recently traveled to the subsequent exit or I recently completed a little journey to my residence. When the vehicle reaches an elevated temperature, it is imperative to promptly cease operation. It is essential to refrain from operating the vehicle under all circumstances, even if it is situated in the center of the interstate. Instead, it is advised to promptly turn off the vehicle and safely maneuver it to the side of the road, afterwards arranging for its towing to an appropriate location.

Given the magnitude of this issue, it might be prudent to consider retesting it under the supervision of an alternative evaluator. It is essential to refrain from disclosing the current situation to the subsequent location. You need an impartial evaluation conducted by an individual devoid of any preexisting biases or preconceptions on the potential issues at hand. The test kits now available are rather inexpensive, and it is highly advisable to actively engage in the testing process by doing the tests independently.

Engaging in this process will enable you to make a better educated choice and acquire knowledge about your vehicle.
